QA Tester Mock Interview Questions & Prep Guide

1

What's the difference between manual testing and automated testing, and when would you use each?

Reference answer

Manual testing is best for exploratory testing, usability checks, and scenarios that change frequently. It's where human intuition and creativity shine. I use manual testing for new features, edge cases I haven't thought of yet, and anything that requires a user's perspective. Automated testing is powerful for repetitive tests that run the same way every time—regression suites, smoke tests, data-driven scenarios. The ROI makes sense when you're running the same test multiple times. In my last role, we automated our checkout flow regression tests because we ran them before every release. That freed up my team to do more exploratory testing on new payment methods instead of clicking through the same scenarios manually. I think the sweet spot is using automation to handle the repetitive heavy lifting and reserving manual testing for the high-value, high-risk areas where judgment matters.

2

What are the different types of software testing?

Reference answer

Software testing includes manual, automation, functional, and non-functional testing. Specific types comprise unit, integration, system, acceptance, regression, load, and security testing. Each of these types has its purpose and ensures different aspects of software functionality and performance meet specified requirements before release.

3

How do you perform visual testing?

Reference answer

Visual testing can be performed manually, where testers visually inspect the application for UI inconsistencies. However, this method can be time-consuming and prone to human error. Many testers use Image Comparison techniques: they capture baseline screenshots of UI elements and compare them with new screenshots to detect unexpected changes. Even so, this approach may generate false positives. Using visual regression testing tools helps reduce false positives and improves efficiency.

4

How do you define test strategy for a new product?

Reference answer

By aligning risks, timelines, and business goals.

5

What is Static Testing?

Reference answer

Static Testing involves reviewing the documents to identify the defects in the early stages of SDLC. In static testing, we do code reviews, walkthroughs, peer reviews, and static analysis of a source code by using tools like StyleCop, ESLint, etc.

6

How do you integrate automation into CI/CD pipelines?

Reference answer

The goal of integration automation into CI/CD pipelines is to ensure continuous validation of code changes. Typically, smoke tests are executed on every build to catch critical failures early, while larger regression suites run at later stages. Also, proper reporting and alerting mechanisms are essential to address failures rapidly without blocking delivery.

7

What is Walk Through?

Reference answer

A walkthrough is an informal meeting conducts to learn, gain understanding, and find defects. The author leads the meeting and clarifies the queries raised by the peers in the meeting.

8

What is Concurrency Testing?

Reference answer

Concurrency testing means accessing the application at the same time by multiple users to ensure the stability of the system. This is mainly used to identify deadlock issues.

9

What is the lifecycle of a Quality Assurance Process?

Reference answer

Every process in Quality Assurance involves the PDCA (Plan Do Check Act) cycle, often known as the Deming cycle. The following are the phases of this cycle: - Plan: The organisation should plan and develop process-related objectives, as well as the methods necessary to provide a high-quality final product. Here, Quality Assurance ensures that the planning made takes into consideration the quality of the product. - Do: This phase involves process development and testing, as well as "doing" changes to processes. Here, Quality Assurance ensures that the processes followed during development maintain the quality of the product. - Check: In this phase, processes are monitored, modified, and checked to see if they achieve the intended goals. Here, Quality Assurance ensures that the processes are checked thoroughly so that no defects might be missed. - Act: In this phase, a Quality Assurance tester should take the steps that are required to improve the processes. These stages are done to guarantee that the organization's procedures are assessed and improved on a regular basis.

10

What is White Box Testing?

Reference answer

White Box Testing is also called as Glass Box, Clear Box, and Structural Testing. It is based on applications internal code structure. In white-box testing, an internal perspective of the system, as well as programming skills, are used to design test cases. This testing usually was done at the unit level. Various white-box testing techniques are: - Statement Coverage - Decision Coverage - Condition Coverage - Multiple Condition Coverage

11

What is STLC (Software Testing Lifecycle)?

Reference answer

STLC (Software Testing Life Cycle) identifies what test activities to carry out and when to accomplish those test activities. Even though testing differs between Organizations, there is a testing life cycle.

12

What are common QA challenges in Agile projects?

Reference answer

- Changing requirements - Short test cycles - Integration with DevOps - Continuous Testing challenges

13

What is the difference between project risk and product risk?

Reference answer

Project risk refers to potential adverse events or conditions that could threaten the successful completion of a project. These risks are often related to project management aspects such as timelines, resource availability, budget constraints, and stakeholder engagement. For example, a project risk could be the risk of delays due to supply chain disruptions or the risk of budget overruns due to unexpected costs. Product risk, on the other hand, pertains to factors that could affect the quality or performance of the product being developed. This includes risks associated with design flaws, faulty development processes, integration issues, or unmet user requirements. A common product risk is the possibility of introducing bugs that may cause the software to malfunction in a production environment. In summary, while project risks are predominantly concerned with the execution and management of the project, product risks are focused on the end deliverable's quality and performance. Both types of risks must be carefully identified, assessed, and mitigated to ensure successful project completion and a high-quality product.

14

How would you test a login page?

Reference answer

Test valid and invalid credentials, empty fields, error messages, and session behavior.

15

What is Test Case?

Reference answer

Test cases are the set of positive and negative executable steps of a test scenario which has a set of pre-conditions, test data, expected result, post-conditions and actual results.

16

Explain the different test levels and give examples.

Reference answer

Test levels refer to the stages in the testing process where tests are conducted. The primary test levels are:Unit Testing: Testing individual components or modules of the software. Example: Testing a single function in a codebase to ensure it returns the correct output. Integration Testing: Testing the interaction between integrated modules or services. Example: Testing API interactions between a web application and a database. System Testing: Testing the entire system as a whole to ensure it meets the specified requirements. Example: Conducting end-to-end testing of an e-commerce application to validate the user journey from product search to checkout. Acceptance Testing: Testing the system's compliance with business requirements and readiness for deployment. Example: User Acceptance Testing (UAT) where end-users test the application to confirm it meets their needs and expectations.

17

What is defect cascading in Software testing?

Reference answer

In software testing, defect cascading is the scenario in which one defect leads to the occurrence of several other defects in a program. If a defect goes unnoticed during testing or if it doesn't get reported, it has the potential to trigger other problems. The result is that multiple defects arise during the later stages of the production process.

18

What is a test scenario?

Reference answer

A test scenario is a high-level description of a test case from a real user's perspective. It describes the overall flow of the testing process, including the various conditions and variables that need to be tested.

19

You need to establish that the person will work well in the team. How do you evaluate a candidate's ability to work in a team environment during an interview?

Reference answer

The best approach is to present scenarios and ask the candidate what they think. For example: 'It's 4pm Friday afternoon and Bob, a developer, has agreed to work back to fix a high-severity bug. We need a tester to validate the fix and you're the only one available but you had a dinner arrangement. What would you propose?' This evaluates whether the candidate is useless ('Sorry, I can't miss dinner'), thinks outside constraints ('Are there really no other testers available?', 'Can I validate it on Saturday morning?', 'Can Bob work some other time on the weekend?'), or is adaptable ('I could put off dinner just this once').

20

Tell me about a time you missed a bug. How did you handle it?

Reference answer

Use the STAR method to compose your answer. Describe the situation you were in when you missed the bug, the tasks you were responsible for, the role you played, the actions you took to resolve the missed bug, and the results of your actions. Take this opportunity to exhibit self-awareness around past work-related mistakes and confidence in being able to handle them.

21

What is the difference between alpha and beta testing?

Reference answer

Alpha and beta testing are both types of acceptance testing, but they differ in terms of who performs them and the environment in which they are carried out: - Alpha Testing: - Conducted by internal testers, such as developers, QA team members, or employees from within the organization. - Performed in a controlled environment and often before the product is released to external users. - Focuses on identifying major bugs, issues, and performance problems that could affect the product's release. It is more rigorous and involves checking all features of the application. - Alpha testing typically occurs during the development phase just before the software is ready for beta testing. - Beta Testing: - Conducted by external users or a selected group of real users outside the development team. - Performed in a real-world environment to gather user feedback and identify any remaining issues that were missed during alpha testing. - Beta testing is usually the final phase of testing before a product is released to the public. - The goal of beta testing is to get feedback on usability, performance, and stability from a broader group of users. In summary, alpha testing is done internally by the team before release, while beta testing is done by real users in the target market before finalizing the product.

22

You find two defects: one high-severity, one high-priority. Which do you test first?

Reference answer

If there are two such defects, I would test the high-priority defect first, as it is a business-critical issue for stakeholders. However, the one with high severity should also be taken quickly, as it may impact the core functionality. Tip: For such questions, clearly explain the trade-offs.

23

What is regression testing and why is it important?

Reference answer

Regression testing is re-running old tests after changes to make sure nothing broke like checking that a new feature didn't mess up existing ones. For example, if you add a search bar to an e-commerce app, you'd retest adding items to the cart to ensure it still works. It's crucial because software updates can introduce sneaky bugs, and it keeps the product stable over time. Automation helps make this faster for big projects.

24

What are the Benefits of Acceptance Testing?

Reference answer

Acceptance testing is based on user requirements and function processing. It is also known as User Acceptance Testing (UAT). It is a process that verifies if a solution is conforming to specified requirements and user requirements or not. It is done by the customer before accepting the final product. Some of the benefits of user acceptance testing are: - It increases the satisfaction of the customer as they test the application itself. - Reduces the risk of defects being identified in the production. - This will help end-users to gain skills and confidence while using the new system prior to going live. - It improves the requirement definition document as the client tests the requirement definition according to his needs. - The information gathered through acceptance testing is used by the stakeholders to better understand the requirements of the targeted audience.

25

How Do You Prioritize Your Work When Faced with Multiple Tasks?

Reference answer

Prioritization is based on business needs, severity, and deadlines. The most critical issues with high impact on users are prioritized first. Proper communication with stakeholders also ensures alignment on what tasks need immediate attention.

26

How do you perform load testing and stress testing, and why are these types of testing important for applications with high user traffic?

Reference answer

Load testing assesses system performance under expected load, while stress testing evaluates performance under extreme conditions. Both are vital for ensuring application scalability and stability.

27

What does the term "quality audit" mean?

Reference answer

A quality audit refers to the systematic evaluation of the quality control system's effectiveness. You can think of a quality audit as a test of how well quality is maintained throughout the development process.

28

What is Test Scenario?

Reference answer

Test Scenario is a detailed document that covers end to end functionality of a software application that can be tested. It is also known as Test Possibility or Test Condition. In this, the testers need to put themselves in the place of the user as they test the software application from the user's point of view. Read More - Test Scenario.

29

What do you mean by monkey testing in the context of quality assurance?

Reference answer

Monkey testing is a software testing technique in which the tester inserts any random inputs into the software application without using predefined test cases and observes the software program's behaviour to see if it crashes. The goal of monkey testing is to use experimental ways to uncover faults and problems in software applications. Monkey testing is a sort of black-box testing that involves supplying random inputs to a system in order to check its behaviour, such as whether it is crashing or not. Monkey testing does not necessitate the creation of test cases. It can also be automated, in the sense that we can develop programs or scripts to produce random inputs in order to test the system's behaviour. When undertaking stress or load testing, this technique comes in handy. Monkeys are divided into two categories: - Smart Monkeys: The smart monkeys are those who have a basic understanding of the application. They know which of an application's pages will redirect to which page. They also know whether the inputs they're giving are valid or not. If they discover an error, they are wise enough to report it as a bug. They are also aware of the menus and buttons. - Dumb Monkeys: Dumb Monkeys are individuals who are completely unaware of the application. They have no idea where an application's pages will reroute. They give random inputs and are unaware of the application's beginning and finish points. Despite the fact that they have no knowledge of the application, they discover bugs such as environmental failure or hardware failure. They also have limited knowledge of an application's functioning and user interface.

30

Explain the role of testing in software development?

Reference answer

Software testing comes into play at different times in different software development methodologies. There are two main methodologies in software development, namely Waterfall and Agile. In a traditional waterfall software development model, requirements are gathered first. Then a specification document is created based on the document, which drives the design and development of the software. Finally, the testers conduct the testing at the end of the software development life cycle once the complete software system is built. An agile software development model works in small iterations. You test the software in parallel as it is getting built. The developers build a small functionality according to the requirements. The testers test it and get customer feedback, which drives future development.

31

What are the three different testing approaches?

Reference answer

Testing approaches can be broken down into white box, black box, and grey box testing. White box testing focuses on the code structure and is usually done by testers with coding skills. Black box testing instead relies on specifications and requirements. Grey box testing involves testers who have a relatively small degree of knowledge about the software. Look for your interviewee to understand the nuances of these different testing approaches and common scenarios where each would be applicable.

32

What is the Page Object Model (POM) in Selenium?

Reference answer

POM is a design pattern where each webpage is represented as a class, and elements are defined within it to improve maintainability and reusability.

33

What is Installation Testing?

Reference answer

It is to check whether the application is successfully installed and it is working as expected after installation.

34

What is Selenium?

Reference answer

Selenium is an open-source tool for automating web applications. It supports multiple browsers and programming languages like Java, Python, and C#.

35

How do you handle defect triage meetings?

Reference answer

I explain the impact clearly and align the severity with business risk.

36

What is the difference between AI-assisted testing, autonomous testing, and agentic QA?

Reference answer

Example Answer: Think of it as a spectrum of autonomy. AI-assisted testing is where most teams are today: AI helps with individual tasks like suggesting test cases or identifying duplicates, but a human manages the overall process. Autonomous testing goes further, with AI systems that can execute and maintain tests with minimal human intervention, including self-healing when the application changes. Agentic QA is the most advanced end of the spectrum: goal-directed AI agents that handle the full testing lifecycle (from requirements analysis through execution through maintenance) in a continuous loop, with humans setting objectives and reviewing outcomes rather than managing each step.

37

Explain test scenarios, test scripts, and test cases in software testing.

Reference answer

- Test Case: Test Cases are a series of actions executed during software development to verify a particular feature or function. A test case consists of test steps, test data, preconditions, and postconditions designed to verify a specific requirement. - Test Scenario: Usually, a test scenario consists of a set of test cases covering the end-to-end functionality of a software application. A test scenario provides a high-level overview of what needs to be tested. - Test Scripts: When it comes to software testing, a test script refers to the set of instructions that will be followed in order to verify that the system under test performs as expected. The document outlines each step to be taken and the expected results.

38

Can you explain the difference between manual testing and automated testing, and when is each approach appropriate?

Reference answer

Manual testing involves human testers executing test cases, while automated testing uses scripts or tools to perform tests. Manual testing is suitable for exploratory, usability, and ad-hoc testing, while automated testing is efficient for repetitive and regression testing.

39

What are common automation testing tools?

Reference answer

Common automation testing tools include Selenium, JUnit, TestNG, Postman, and Jenkins. These tools facilitate writing scripts for repetitive tasks, enable automated regression tests, and streamline continuous integration, helping to identify defects earlier and improve overall product quality.

40

How do you prioritize multiple tasks?

Reference answer

To prioritize multiple tasks:Assess Urgency and Importance: Use frameworks like the Eisenhower Matrix to determine which tasks are urgent and important. Set Clear Deadlines: Assign deadlines based on project timelines and priorities. Communicate: Regularly communicate with stakeholders to understand their priorities and adjust my tasks accordingly. Break Down Tasks: Break down larger tasks into smaller, manageable steps and prioritize them accordingly. Use Tools: Utilize project management tools like Jira or Trello to track and prioritize tasks effectively.

41

What is Exploratory Testing?

Reference answer

Exploratory Testing is an informal testing approach where testers explore the application without predefined test cases.

42

Differentiate between Test Plan and Test Strategy.

Reference answer

- Test Plan: A test plan is a document that illustrates the test procedure, destinations, timetable, estimation, and expectations, as well as the assets needed for testing. It motivates us to determine the effort required to approve the kind of application being tested. The test plan serves as a diagram to guide software testing exercises as a well-defined method that the test manager closely monitors and controls. Test plan id, highlights to be tested, test systems, testing assignments, highlights pass or bomb criteria, test expectations, duties, and timeline, and so on are all included in the test plan. - Test Strategy: In software testing, a test strategy is a collection of guiding principles that specifies the test design and control how the software testing process is carried out. The Test Strategy's goal is to give a systematic method to software testing so that quality, traceability, reliability, and better planning may be assured. The following table lists the differences between Test Plan and Test Strategy: | Test Plan | Test Strategy | |---|---| | A software project test plan is a document that specifies the scope, purpose, approach, and emphasis of a software testing process. | A test strategy is a set of rules that describes how to develop tests and outlines how they should be carried out. | | Test plan elements include the following: | Following are the components of a test strategy : | | The specifications of the testing process are described in the test plan. | The general approaches are described in the test strategy. | | A testing manager or lead executes a test plan that specifies how to test when to test, who will test, and what to test. | The project manager implements a test strategy. It specifies which approach to use and which module to test. | | Changes to the test plan are possible once it has been created. | It is impossible to alter the test strategy once it has been created. | | Test planning is done to identify risks by determining potential issues and dependencies. | This is a long-term approach. You can use information that isn't specific to a project to create a test strategy. | | A test plan can exist individually. | Test strategy is frequently found as an element of a test plan in smaller projects. | | It is established at the project level. | It is configured at the organisational level and can be utilised across different projects. |

43

What is a Use Case and what does it include?

Reference answer

A Use Case is a document that describes the user action and system response for a particular functionality. It includes cover page, Revision History, Table of Contents, Flow of Events (normal flow and alternative flow), Exceptions, Special Requirements, Pre-conditions and Post-conditions.

44

How do you ensure that you have covered everything during your testing process?

Reference answer

To ensure that I've covered everything during my testing process, I use traceability matrices, which map test cases to requirements. This helps me ensure that all requirements are covered by at least one test case. Furthermore, I organize my test cases into functional areas and different types of testing, which also helps ensure coverage.

45

What is the difference between verification and validation in QA?

Reference answer

Verification ensures that the product is built according to the requirements and design specifications (Are we building the product right?). Validation ensures that the product meets the user's needs and requirements (Are we building the right product?).

46

How would you test a payment gateway integration?

Reference answer

I'd test successful payments using different methods like cards, UPI, and net banking. Then failure cases like insufficient funds, expired card, wrong CVV, network timeout, and duplicate payment on double click. I'd verify refund flow (full and partial), transaction ID mapping, and reconciliation with order amount. Security testing includes PCI-DSS checks, no card data stored, HTTPS, and tokenization. I would use sandbox/test card numbers and also test idempotency for repeated requests.

47

What is a Test Script?

Reference answer

Test scripts system under test. - These are the programs that run tests on the software product/ application. - The tester has to write and run test scripts to validate if the application's outcome meets the business requirements. Read More - Test scripts.

48

What is severity vs priority?

Reference answer

Severity shows impact. Priority shows urgency of fixing the issue.

49

What is the importance of creating test cases?

Reference answer

Test cases serve as a blueprint for testing and help ensure that all aspects of the software are thoroughly tested. They help to identify any defects in the software and ensure that the software meets the specified requirements. Test cases also serve as a reference for regression testing and help to track the progress of testing.

50

What are the criteria for deciding what to automate?

Reference answer

Automate repetitive tests (like regression), stable features that won't change soon, high-risk areas (e.g., login security), and things that need to run often in CI/CD. Avoid automating if it's exploratory, UI-heavy without stable elements, or if setup time outweighs benefits. Look at ROI — does it save time long-term?

51

What are test management tools?

Reference answer

Test management tools help organize and manage the testing process. They provide features for:Test Planning: Creating test plans, defining scope, and scheduling. Test Case Management: Writing, organizing, and maintaining test cases. Test Execution: Running test cases and tracking execution status. Defect Management: Logging and tracking defects. Reporting and Analytics: Generating reports and metrics on testing activities. Collaboration: Facilitating communication among testing teams and stakeholders. Popular test management tools include Jira, TestRail, Quality Center, and Zephyr.

52

What is user acceptance testing (UAT)?

Reference answer

UAT is the final phase of testing where the software is tested by the end users to ensure it meets their requirements and works as expected in real-world scenarios.

53

How would you test a signup flow?

Reference answer

Verify field validations, password rules, email confirmation, and success messages.

54

What is non-functional testing?

Reference answer

Non-functional testing tests the system's non-functional requirements, which refer to an attribute or quality of the system explicitly requested by the client. These include performance, security, scalability, and usability. Non-functional testing comes after functional testing. It tests the general characteristics unrelated to the functional requirements of the software. Non-functional testing ensures that the software is secure, scalable, high-performance, and won't crash under heavy load.

55

What is the difference between QA and QC?

Reference answer

Quality Assurance focuses on preventing defects by improving development and testing processes. It involves activities like defining standards, designing testing strategies, and improving workflows. Quality Control, on the other hand, focuses on identifying defects in the product itself and mainly involves executing test cases, validating functionality, and reporting issues. In simple terms, QA improves the process while QC verifies the product.

56

Can you describe and give me your thoughts on The Testing Pyramid?

Reference answer

Here, I'm really just looking for familiarity with some of the basic concepts we use as QA engineers. I want to know that the candidate understands that all work environments will be a blend of unit, integration, and e2e tests.

57

What is a Cause-effect Graph?

Reference answer

Cause-effect Graph is a black box testing technique that is used to represent the relationship between a given outcome and all the factors that influence the outcome. It is based on the collection of requirements and used to determine the minimum possible test cases that can cover a minimum test area of the software. The main advantage of this testing technique is that it reduces the test execution time and cost. Read More - Cause-effect Graph

58

What is a 'traceability matrix'?

Reference answer

A 'traceability matrix' is a document that testers use to track and confirm the development process of specific components. It helps businesses compare the components of the system and provides facts about the project's completion requirements. Features include identifiers in the top row and identifications in the left columns.

59

What is performance testing?

Reference answer

Performance testing is a type of testing that evaluates how well a system performs under various conditions. It focuses on assessing the responsiveness, stability, and speed of the application, especially under expected and peak load conditions. Types of performance testing include: - Load Testing: Measures the system's performance under normal and expected loads to ensure it can handle typical user activity. - Stress Testing: Tests the system's behavior under extreme conditions, such as a high number of concurrent users or heavy data input, to see how it responds under stress. - Scalability Testing: Evaluates how well the application can handle an increasing number of users or transactions over time. - Endurance Testing: Measures how the system performs over an extended period under a sustained load to detect issues like memory leaks.

60

Compare manual testing vs automated testing. Should QA teams move to automation?

Reference answer

| Aspect | Manual Testing | Automated Testing | |---|---|---| | Definition | Testers manually perform the actions in the application. Tests are typically written in text editors, Xray, test management tools, or spreadsheets. | Testers define the interaction steps, then write automation scripts to execute them. Scripts can run on-demand or on schedule. | | Cost | Lower upfront cost; depends on human testers. Difficult to scale. | Investment in developers/automation engineers and tools (automation frameworks, CI, test management, defect tracking). | | Test Coverage | Low | High | | Reusability | Test content cannot be reused easily. | Test content is highly reusable, including: | | Types of Testing | Exploratory testing Usability testing Ad hoc testing | Regression testing Integration testing Data-driven testing Performance testing | | Tester | Business stakeholders Manual test engineers | Developers or automation engineers | If testing is repetitive and requires frequent regression cycles, teams should consider automation. Manual testing still adds value for exploratory or ad-hoc scenarios. The decision depends on project type, goals, and complexity. Here is a guide to move from manual testing to automation. It's also worth noting that this question is evolving. In 2026, the conversation is shifting from "manual vs. automated" to "manual vs. automated vs. agentic QA," where AI agents handle test generation, execution, and maintenance autonomously while humans focus on strategy and judgment.

61

What is a Use case?

Reference answer

A use case is a detailed description of how a user interacts with a system to achieve a specific goal. It includes the steps a user takes, the system's responses, and the flow of events. Use cases help in understanding the system's functional requirements and are used as a basis for creating test cases. They provide a clear picture of how the system should behave from the user's perspective.

62

Explain risk in the context of quality assurance. What are the five dimensions of risk?

Reference answer

When it comes to software testing, Risks are potential issues that could jeopardise the project stakeholders' goals. It's the likelihood of a bad or unfavourable result. A risk is something that has not yet occurred and may never occur; it is a potential concern. The likelihood of a risk becoming an outcome is proportional to the degree of risk linked with the potential for negative consequences. Most people, for example, are expected to have a cold at some point in their lives, frequently multiple times. A healthy person, on the other hand, is spared any major effects. As a result, this individual's overall risk of catching a cold is low. On the other hand, for an elderly person with breathing issues, the risk of catching a cold is significant. As a result, the overall chance of catching a cold in his instance is significant. Following are the five dimensions of risks: - Schedule: Unrealistic schedules, the omission of important activities when drafting a schedule, and other factors could stymie project completion on time. If testing is done from a remote place, an unstable communication link can be regarded as a possible danger. - Client: Ambiguous requirements description, lack of clarity on issues, frequent changes to requirements, and other factors could lead to chaos throughout project execution. - Human Resources: Insufficient resources with the required skill level are not available for the project; Resource attrition - Appropriate training schedules for resources must be designed to balance the knowledge level with resources quitting. Underestimating the training effort could have a negative influence on project completion. - System Resources: The inability to obtain or the delay in obtaining all key computer resources, such as hardware and software tools, or software licences, will have a negative impact. - Quality: A combination of issues such as a shortage of resources, a tight delivery timetable, and frequent changes to requirements will have an impact on the product tested quality.

63

What is Continuous Testing?

Reference answer

Continuous Testing is the automated execution of tests in the CI/CD pipeline.

64

Explain how you would handle testing in a DevOps environment.

Reference answer

Testing in a DevOps environment involves continuous collaboration between development, operations, and QA teams. The goal is to ensure software quality while enabling frequent and reliable releases. Here's how testing is typically handled in a DevOps setting: - Automation: Automation is a core principle in DevOps, and automated tests should be integrated into the continuous integration/continuous deployment (CI/CD) pipeline. This includes unit tests, integration tests, regression tests, and performance tests. - Shift-Left Testing: Testing should be done early and often throughout the development process, not just at the end. This is known as "shift-left testing," where tests are integrated into the early stages of the development cycle, allowing developers to run unit tests and integration tests during the build phase. - CI/CD Integration: Test automation should be part of the CI/CD pipeline. Tests are executed automatically whenever code is committed or merged into the repository. This ensures that quality is maintained with every change, and issues are detected early. - Test Environments: Maintain consistent and reliable test environments using containerization technologies like Docker or Kubernetes to ensure that tests are executed in the same environment as production, minimizing discrepancies due to environment differences. - Continuous Monitoring: In a DevOps environment, monitoring is not limited to production. Test results, logs, and metrics should be monitored continuously to detect issues early in the process. Automated tests are run frequently in the pipeline, and failure alerts are sent to developers for quick resolution. - Collaboration and Communication: QA, development, and operations teams need to work closely together in a DevOps setup. This includes regular communication regarding test progress, bugs, and deployment schedules. A shared responsibility for quality ensures that issues are resolved quickly and efficiently. - Performance and Load Testing: Performance tests should be integrated into the DevOps pipeline, especially for load testing, stress testing, and scalability testing. These can be automated and run on-demand to ensure that new changes do not degrade system performance. - Continuous Testing: Testing is a continuous process in DevOps, and it is done with every commit, every pull request, and every deployment. Continuous testing tools like Jenkins, Travis CI, CircleCI, and GitLab CI can help automate and manage testing across various stages of the pipeline. By integrating testing throughout the DevOps lifecycle, you can maintain high-quality standards while promoting faster and more reliable software delivery.

65

What is the difference between a Standalone application, Client-Server application and Web application?

Reference answer

Standalone application: Standalone applications follow one-tier architecture. Presentation, Business, and Database layer are in one system for a single user. Client-Server Application: Client-server applications follow two-tier architecture. Presentation and Business layer are in a client system and Database layer on another server. It works majorly in Intranet. Web Application: Web server applications follow three-tier or n-tier architecture. The presentation layer is in a client system, a Business layer is in an application server and Database layer is in a Database server. It works both in Intranet and Internet.

66

What is Alpha and Beta Testing?

Reference answer

- Alpha Testing: Done in a development environment before release. - Beta Testing: Done by end users in a real-world setting.

67

Tell me about a time you found a bug that turned out to be a feature or user misunderstanding.

Reference answer

Early in a project, I reported that a user couldn't export data to PDF. I thought it was clearly a bug until the product manager asked me a few clarifying questions. Turned out, the feature wasn't supposed to be in that version yet—it was planned for next quarter. I'd misread the requirements document. Instead of just closing the bug ticket and feeling stupid, I asked the PM how I could have caught that earlier. She suggested I attend the product planning meetings, which I now do. It was a small hiccup, but it taught me to ask questions about what I'm testing before diving in.

What are the different HTTP status codes that a server can return?

Reference answer

An HTTP status code is a three-digit number that indicates the status of an incoming HTTP request, that is, if the request has been completed or not. A server can send the following five types of responses for an HTTP request. - Information (100 - 199): These status codes provide a temporary response. The response consists of the status line and optional headers and terminates by an empty line. - Success (200 - 299): Indicate that the incoming HTTP request was successfully received, understood, and accepted. - Redirect (300 - 399): These status codes indicate further actions the client should take to satisfy the HTTP request. It can mean that the requested resource may have moved temporarily or permanently. It can also redirect the client to another URL. - A client error (400 - 499): Indicate a problem with the client who initiated the HTTP request. - Server error (500 - 599): The 5XX status code indicates a problem on the server while processing the request.

What is a test execution?

Reference answer

Test execution refers to the process of running a test case or a set of test cases on the application or system being tested. This process involves the following steps: - Test Setup: Preparing the testing environment and ensuring that all necessary resources, data, and configurations are available for testing. - Running the Test: Performing the actions defined in the test cases, either manually or through automation tools, while observing the system's behavior. - Capturing Results: Documenting the actual results during test execution and comparing them with the expected results to determine if the test passed or failed. - Reporting Issues: If discrepancies are found between expected and actual results, defects are logged for further analysis and fixing. Test execution is a critical part of the testing lifecycle, as it involves validating the functionality and performance of the application based on the test cases designed earlier.

76

What is Agile testing?

Reference answer

Agile testing is a testing process that follows Agile methodologies, focusing on continuous testing and feedback throughout the development lifecycle, rather than testing only at the end.

77

What is Positive and Negative Testing?

Reference answer

Positive Testing: It is to determine what system supposed to do. It helps to check whether the application is justifying the requirements or not. Negative Testing: It is to determine what system not supposed to do. It helps to find the defects from the software.

Differentiate between Quality Assurance and Testing.

Reference answer

Software Testing: Software testing is a method of investigating a system to see how it works according to product requirements and customer expectations and identify potential flaws. To test the product, find bugs, and see if they've been fixed, a variety of methods are utilised. Customers can use testing to check if the generated product satisfies their expectations in terms of design, compatibility, and functionality, among other things. Validating the product against specifications and client requirements, as well as detecting and reporting flaws, are all part of the testing process. To detect software flaws, it uses a variety of testing methodologies such as functional, non-functional, and acceptability testing. Furthermore, before the product is released to the client, the purpose of software testing is to ensure that any found faults are entirely corrected with no side effects. The following table lists the differences between Quality Assurance and Testing: | Quality Assurance | Testing | |---|---| | It is a subset of the Software Development Lifecycle (SDLC). | It is a subset of Quality Control (QC). | | It is process-oriented. | It is product-oriented. | | It is preventive in nature (tries to prevent defects from being present in the product). | It is corrective in nature (tries to correct defects present in the product). | | Quality Assurance is done to prevent defects in the product. | Testing is done to find and fix defects in the product. | | Quality Assurance ensures that the processes and procedures followed by the team are in place. | Testing confirms that the product conforms to the specifications required. | | In Quality Assurance, the focus is on the processes that operate on the product. | In Testing, the focus is on the end product itself. | | It is a proactive process (a proactive strategy focuses on preventing problems from arising). | It is a reactive process (a reactive approach focuses on reacting to events after they have occurred). | | Quality Assurance needs to be implemented by the whole team. | In Testing, only the testing team is concerned. |

93

How important is it for QA to take part in development planning sessions?

Reference answer

QA teams can work in many ways. Some are part of a larger development team, where data center operations gets together with programmers for regular meetings (or for beer). Others are used to communicating largely among themselves. Similarly, some QA teams come in long after the application design process is complete, while others get involved from Day One. That isn't to suggest that one process is better than another, but both the interviewer and manager should know what the other person expects and desires. A candidate who forgoes planning sessions in favor of some much-needed bug hunting might be focused on the task at hand—and nothing else. Is that good or bad? The answer is up to you. One QA tester may expect to be part of sprint/development planning sessions to better understand the context of each task, and thus to assess each feature's risks and complexity. Another might feel that it'd be more productive to invite goats to a Zoom meeting. As you know, planning sessions are a good way to get in front of theoretical problems before they become actual problems. We hope your interviewee knows it too.

94

What are some challenges you've faced in automation testing?

Reference answer

Challenges in automation testing are common, and they can include: - Flaky Tests: Automation tests can be unstable, leading to false positives or negatives due to factors like timing issues or dependencies on external systems. - High Initial Setup Time: Setting up automated testing frameworks and writing test scripts can be time-consuming, especially for complex applications. - Test Maintenance: As the application evolves, maintaining automated tests to keep them aligned with changing code or user interfaces can be a significant effort. - Handling Dynamic Elements: Websites with dynamic content (e.g., AJAX or SPAs) can be difficult to automate, as elements might not be present at the time of execution. - Resource Constraints: Running automated tests requires hardware and software resources. If resources are not sufficient or tests are not optimized, they can take a long time to execute. - Limited Scope: Some types of tests (e.g., exploratory or usability testing) are difficult to automate. Test automation is most effective for repetitive tasks, but complex scenarios often require manual intervention. - Tool Limitations: Sometimes, the testing tools used may not be suitable for the application's tech stack or the required type of testing, leading to limitations in automation coverage.

95

What is the Page Object Model (POM) in Selenium?

Regular reviews with stakeholders and team members help ensure completeness and alignment with project goals.

98

What is Quality Assurance(QA)?

Reference answer

Software Quality Assurance is a process that works parallel to Software Development. It focuses on improving the process of development of software so that problems can be prevented before they become major issues. Software Quality Assurance is a kind of Umbrella activity that is applied throughout the software process. The five major quality assurance functions are- - Technology Transfer: This involves getting the product design document as well as trial and error data and its evaluation. - Documentation: This function controls the distribution and archiving of the documents. For incorporating any change in the document, a proper change control procedure needs to be adopted. - Validation: In this function, the validation master plan for the system, and approval of test criteria for validating the product and process are also set. - Assuring Quality Products: This function aims at checking and assuring the quality of the software product. - Quality Improvement Plans: In this function, quality improvement plans are generated to check whether the software product meets the requirements. Read More - Quality Assurance (QA).

What are latent and masked defects?

Reference answer

| Term | Definition | |---|---| | Latent Defect | Latent defects are hidden defects, software flaws, that have not yet been detected, and cannot be found until a specific task is performed. | | Masked Defect | Masked defects are defects that cannot be discovered yet as they are hidden behind another portion of defected code. Only once this defect is detected, can the masked defect be identified. |

101

What is a risk-based testing approach?

Reference answer

Risk-based testing (RBT) is an approach to testing where test efforts are focused on areas of the software that pose the highest risk. The primary goal of RBT is to identify the most critical areas of the application that, if they failed, would result in the highest business impact. The approach is structured as follows: - Risk Identification: Identify potential risks, including functional, technical, and business-related risks. This could involve potential security issues, high-value user transactions, or critical features. - Risk Assessment: Assess each risk in terms of probability (likelihood of occurrence) and impact (severity of consequences if it occurs). A risk matrix is often used to categorize risks (e.g., low, medium, high). - Prioritization: Focus testing efforts on high-probability and high-impact risks. For example, critical features that are frequently used by customers or have been problematic in previous releases should be prioritized. - Test Execution: Test the areas that are considered high risk first, and allocate more testing resources to them. As lower-risk areas may not need exhaustive testing, they are allocated fewer resources. Risk-based testing helps ensure that the most critical functionality is tested thoroughly, improving the chances of finding defects that would have the greatest impact on the project or business.

102

What is Canary Testing and when do you perform it?

Reference answer

Canary Testing is a technique used to release a new software feature or update to a small group of users before rolling it out to everyone. This helps identify any potential issues or risks in a controlled environment. It is performed when you want to minimize the impact of possible defects and ensure the update works smoothly for a broader audience.

103

What are the key components of a good test case?

Reference answer

A good test case should include the following components:Test Case ID: A unique identifier for the test case. Title: A brief and descriptive title. Description: A detailed explanation of what the test case is verifying. Preconditions: Any setup or conditions that must be met before executing the test. Test Steps: Step-by-step instructions on how to perform the test. Expected Results: The expected outcome of each step. Actual Results: The actual outcome when the test is executed. Status: Indicates whether the test passed, failed, or is blocked. Comments: Additional information or observations about the test.

107

How do you prioritize your testing tasks?

Reference answer

In my role at Nubank, I use a risk-based approach to prioritize testing tasks. I assess which features are critical to user experience and pose the highest risk if they fail. I utilize tools like JIRA to manage my tasks and keep track of progress. During a recent release, I identified a potential issue in the mobile app that could affect user transactions. By communicating with the development team, we prioritized testing this feature, allowing us to resolve it before the launch, ensuring a smooth user experience.

108

What is a use case?

Reference answer

Use cases are another central element of the QA process, so it's good to have a solid answer ready for this question. A use case refers to a document that outlines an action the user takes and how the system responds. It's used to examine how a specific element of application functions.

109

Can you explain what is meant by 'boundary value analysis'?

Reference answer

Boundary Value Analysis is a testing technique used to identify errors at boundaries rather than finding those exist in the center of the input domain. It involves testing the boundary values of valid and invalid partitions. The rationale is that many faults are observed at the extreme ends of input domains.

110

Can Quality Assurance Professionals help resolve production issues?

Reference answer

Yes, Quality Assurance (QA) professionals can play a crucial role in resolving production issues. Their expertise in understanding the system's functionality, along with their planned approach to testing and problem-solving, equips them with the tools necessary to debug and troubleshoot production problems effectively. QA professionals can assist by performing root cause analysis to identify the underlying issues causing the problem. They can replicate the production environment to reproduce the issue, which helps in understanding its impact and scope. By working closely with developers, they facilitate a collaborative approach to bug fixing and ensuring that any fixes introduced do not unintentionally affect other parts of the system. Their involvement also ensures that comprehensive regression testing is performed before the issue is marked as resolved, thereby maintaining the overall integrity and stability of the production environment. This proactive involvement not only helps in quick resolution but also contributes to the implementation of preventative measures to avoid similar issues in the future.

111

What automation tools have you used and how do you select them?

113

What is the importance of version control in QA?

Reference answer

Version control is crucial in software quality assurance (QA) because it helps manage and track changes to the codebase, test scripts, and other artifacts throughout the software development lifecycle. The benefits of version control in QA include: - Tracking Changes: Version control systems (VCS) like Git, SVN, or Mercurial allow teams to track changes to both the source code and testing scripts. This ensures that testers are working with the correct version of the software and that changes are properly documented. - Collaboration: Multiple team members (developers, testers, and QA engineers) can work on the same project without conflict, as version control manages concurrent changes to files. - Rollback Capability: If an issue is introduced after changes, version control allows teams to roll back to a previous, stable version of the code or test scripts. - Audit Trail: Version control provides an audit trail of who made which changes, helping with accountability and traceability. - Parallel Development and Testing: Version control supports parallel development and testing on different features or modules, reducing the risk of conflicts and enabling better test coverage. Version control ensures that the QA team is always working with the most up-to-date and accurate versions of the software and testing artifacts.

114

Can you describe the different types of test coverage techniques?

Reference answer

Among the different types of test coverage techniques are: - Statement/Block Coverage: Measures how many statements in the source code have been successfully executed and tested. - Decision/Branch Coverage: This metric measures how many decision control structures were successfully executed and tested. - Path Coverage: This ensures that the tests are conducted on every possible route through a section of the code. - Function coverage: It measures how many functions in the source code have been executed and tested at least once.

115

What are test entry and exit criteria?

Reference answer

Entry criteria are conditions that must be met before testing starts, like approved requirements, deployed build, test environment ready, and test data prepared. Exit criteria define when testing can stop, like all critical test cases executed and no open blocker defects. They are defined in the test plan. If exit criteria are not met, risk must be documented and approved by stakeholders. This ensures controlled and structured testing process.

116

How would you prioritize testing when time is limited?

Reference answer

When time is constrained, testing needs to be risk-driven. The focus should be on areas that have the highest impact on users or business, such as critical workflows and recently updated areas. `Rather than testing the entire software, the preferred approach is to ensure that the most vulnerable and important parts are stable. For that, smoke testing and critical path validation usually take priority. Instead of testing everything, it's more effective to ensure the most important parts are stable. Smoke testing, critical path validation, and recent changes usually take priority.

117

What if the software is so buggy it can't really be tested at all?

Reference answer

If the software is so buggy, the first thing we need to do is to report the bugs and categorize them based on Severity. If the bugs are critical bugs then it severely affects schedules and indicates deeper problems in the software development process. So you need to let the manager know about the bugs with proper documentation as evidence.

118

How would you communicate with a client if they found an error in your status report?

Reference answer

Use the STAR method to describe a hypothetical situation in which a client notices a status report error, the tasks you'd be responsible for in this scenario, the actions you would take to resolve the error and communicate with the client, and the results you would anticipate. Take the opportunity to emphasize your communication and problem-solving skills, as well as your resilience when facing challenges.

119

Critical bug before release, fix needs 3 days – what do you do?

Reference answer

First, I assess impact: user count affected, data loss, or security risk. Then I inform stakeholders with clear severity and evidence. We evaluate options like delaying release, feature flagging, partial rollout, or releasing with hotfix plan. Risk should be documented and formally accepted by product/business. Monitoring and support team should be prepared if released with known issue.

120

The test summary report is typically presented to stakeholders, including project managers, developers, and other relevant parties.

133

How do you decide when to automate a test case versus performing it manually?

Reference answer

When deciding whether to automate a test case, I consider factors like repetition, complexity, and the likelihood of human error. Test cases that are repetitive, require extensive data input, or need to be run across multiple environments are strong candidates for automation. On the other hand, exploratory and usability tests are better suited for manual execution to assess user behavior and interface quality.

134

What is the difference between Dynamics 365 CRM and ERP modules?

Reference answer

Dynamics 365 CRM focuses on managing customer relationships, sales, marketing, and service. ERP modules handle internal operations such as finance, supply chain, inventory, and production.

The most critical aspect is thorough and comprehensive testing coverage to ensure that the software meets all its functional and non-functional requirements and that any potential bugs or defects are discovered and addressed before the software is released to the market.

141

What is the difference between verification and validation?

Reference answer

Verification and validation are both essential activities in software testing, but they focus on different aspects of the software: - Verification: Verification is the process of evaluating whether the software meets the specifications and whether it was built correctly. It is a static process that checks if the product is being developed according to the predefined requirements and standards. - Example activities: Reviews, inspections, and walkthroughs of documents, code, or design. - Key Question: "Are we building the product right?" - Validation: Validation, on the other hand, is the process of evaluating whether the software meets the user's needs and whether it performs as expected in real-world scenarios. It is a dynamic process that involves executing the application to check if it behaves correctly in the intended environment. - Example activities: Functional testing, system testing, acceptance testing. - Key Question: "Are we building the right product?" In simple terms, verification ensures that the software is being built correctly, while validation ensures that the software meets the user's needs and expectations.

142

What is the importance of Agile testing in the context of Agile development methodology?

Reference answer

Agile testing is essential in Agile development because it ensures continuous feedback and quality checks throughout the development lifecycle. Unlike traditional testing, which happens after development is complete, Agile testing occurs iteratively at every sprint. This allows teams to identify and address issues early, reducing the cost and effort of fixing defects.

143

What is Split Testing?

Reference answer

Refer A/B testing.

145

What is cross-browser testing?

Reference answer

Cross-browser testing ensures the application works correctly across different browsers and versions like Chrome, Firefox, Safari, and Edge. Challenges include CSS rendering differences, JavaScript engine behavior, and mobile browser variations. To manage this, define a browser support matrix based on user traffic. Tools like BrowserStack or Sauce Labs help test across combinations. Critical flows can be automated while layout issues are checked manually.

146

Write some common mistakes that lead to major issues.

Reference answer

Some common mistakes include: - Poor Scheduling - Underestimating - Ignoring small issues - Not following the exact process - Improper resource allocation

147

Define function and non-functional testing

Reference answer

Functional Testing: Functional testing is a type of black-box testing method that looks at the software's functional requirements, making sure it fulfils these and solves the end-user's problems. Non-Functional Testing: Non-functional testing focuses on qualities that have been specifically outlined by the client, such as performance or usability.

148

What is an Error?

Selenium consists of the following components: - Selenium Remote Control (RC). - Selenium Integrated Development Environment (IDE). - Selenium WebDriver. - Selenium Grid.

151

What are the principles of software testing?

Reference answer

Software testing is governed by seven principles: - Absence of errors fallacy: Even if the software is 99% bug-free, it is unusable if it does not conform to the user's requirements. Software needs to be bug-free 99% of the time, and it must also meet all customer requirements. - Testing shows the presence of errors: Testing can verify the presence of defects in software, but it cannot guarantee that the software is defect-free. Testing can minimize the number of defects, but it can't remove them all. - Exhaustive testing is not possible: The software cannot be tested exhaustively, which means all possible test cases cannot be covered. Testing can only be done with a select few test cases, and it's assumed that the software will produce the right output in all cases. Taking the software through every test case will cost more, take more effort, etc., which makes it impractical. - Defect clustering: The majority of defects are typically found in a small number of modules in a project. According to the Pareto Principle, 80% of software defects arise from 20% of modules. - Pesticide Paradox: It is impossible to find new bugs by re-running the same test cases over and over again. Thus, updating or adding new test cases is necessary in order to find new bugs. - Early testing: Early testing is crucial to finding the defect in the software. In the early stages of SDLC, defects will be detected more easily and at a lower cost. Software testing should start at the initial phase of software development, which is the requirement analysis phase. - Testing is context-dependent: The testing approach varies depending on the software development context. Software needs to be tested differently depending on its type. For instance, an ed-tech site is tested differently than an Android app.

152

What is the software testing life cycle?

Reference answer

Similar to software development, testing has its life cycle. During the testing, a tester goes through the following activities. - Understand the requirements: Before testing software or a feature, the tester must first understand what it is supposed to do. If they don't know how the software is supposed to work, they can't test it effectively. - Test Planning and Case Development: Once the tester has a clear understanding of the requirements, they can create a test plan. It includes the scope of testing, i.e., part of software under test and objectives for testing. Various activities are involved in planning the test, such as creating documentation, estimating the time and efforts involved, deciding the tools and platforms, and the individuals who will be conducting the tests. - Prepare a test environment: The development happens in a development environment, i.e., on a developer's computer that might not represent the actual environment that the software will run in production. A tester prepares an environment with the test data that mimics the end user's environment. It assists with realistic testing of the software. - Generate the test data: Though it is impossible to do exhaustive testing of the software, the tester tries to use realistic test data to give them the confidence that the software will survive the real world if it passes the tests. - Test Execution: Once the tester has a complete understanding of the software and has a test environment set up with the test data, they execute the test. Here, execution means that the tester runs the software or the feature under test and verifies the output with the expected outcome. - Test Closure: At the end of the test execution, there can be two possible outcomes. First, the tester finds a bug in the part of the software under test. In this case, they create a test record/bug report. Second, the software works as expected. Both these events indicate the end of the test cycle.

153

Talk about how you approach flexibility in your testing efforts. What would you do if you needed to get a release out tomorrow and none of your regression testing was done?

Reference answer

Sometimes we have to face unrealistic deadlines, and I want to know how someone will respond to pressure and a ticking clock. I'd like to hear about how they would prioritize their testing efforts, and how they would communicate to management about their feelings of readiness for a release. I also want to know that if they feel that a release is unsafe, that they're willing to throw up a red flag and inform the rest of their team.

154

Describe your approach to testing an API. What would you test, and what tools would you use?

Reference answer

I'd test the happy path first—making valid requests and confirming the response is correct. Then I'd test negative scenarios: invalid data types, missing required fields, malformed requests. I'd verify that error responses are appropriate—404 for not found, 401 for unauthorized. I'd test boundary conditions: what happens with very large numbers, empty strings, null values? I'd use Postman or a similar tool to create a test collection with these scenarios. I'd also test performance—how fast does the API respond? Can it handle concurrent requests? For authentication, I'd verify that unauthorized users can't access endpoints they shouldn't. I'd test for injection attacks, especially if the API accepts user input. The nice thing about API testing is it's more stable than UI testing—there's no flaky element selectors. You're just verifying requests and responses, which is very repeatable.

155

What is Acceptance Testing?

Reference answer

It is also known as pre-production testing. This is done by the end-users along with the testers to validate the functionality of the application. After successful acceptance testing. Formal testing conducted to determine whether an application is developed as per the requirement. It allows the customer to accept or reject the application. Types of acceptance testing are Alpha, Beta & Gamma.

156

What are the principles of Software Testing?

Reference answer

- Testing shows defects. - Exhaustive testing is impossible. - Early testing saves time and cost. - Defects cluster together. - Pesticide Paradox (same tests lose effectiveness over time). - Testing depends on context. - Absence of errors is a fallacy.

157

What is Dynamic Testing?

Reference answer

Dynamic testing involves the execution of code. It validates the output with the expected outcome.

158

How do you go about learning a new product?

160

What is Test-Driven-Development?

Reference answer

Test-Driven-Development (TDD) is a popular software development technique, first introduced by Kent Beck in his book with the same name, published in 1999. In TDD, a developer working on a feature first writes a failing test, then writes just enough code to make that test pass. Once they have a passing test, they add another failing test and then write just enough code to pass the failing test. This cycle repeats until the developer has the fully working feature. If the code under the test has external dependencies such as database, files, or network, you can mock them to isolate the code. Benefits of TDD: - Writing tests first forces you to think about the feature you are trying to build, helping you produce better code. - As you always have a working set of tests at hand, a failing test indicates that the problem is with the code you just added, reducing the time spent in debugging. - Writing tests help the developer to clarify the requirements and specification. It's challenging to write good tests for a poor set of requirements. - It's tough to produce high-quality software unless you can test the software after each new change. You can never be sure that your new code didn't break the working software. TDD gives you the confidence to add new code, as you already have a test in place.

161

You need to ensure that a web application works seamlessly across multiple browsers. How would you approach this?

163

When would you choose manual testing over automation?

Reference answer

Go manual for ad-hoc or exploratory testing, where you need human intuition, like checking usability or visual bugs. It's also better for short-term projects, one-time tests, or when the UI changes a lot; automation scripts would break too often. Plus, if the team lacks coding skills or budget for tools, the manual testing keeps things simple.

164

What is Modification Request?

Reference answer

Modification request (MR) in software development is used by clients to change the existing functionality of a software.

165

What is accessibility testing?

Reference answer

Accessibility testing ensures that web applications are usable by people with disabilities, including visual, auditory, physical, and cognitive impairments.This type of testing checks for compliance with accessibility standards such as WCAG (Web Content Accessibility Guidelines).

Usually, this process will be carried out by domain experts. They perform testing just by exploring the functionalities of the application without having the knowledge of the requirements.

171

What is the purpose of smoke testing and sanity testing, and how do they differ from other types of testing?

Reference answer

Smoke testing ensures that the critical and basic functionalities of an application work after each build. Sanity testing verifies specific areas affected by code changes. They are quick checks before more extensive testing.

172

What is A/B testing?

Reference answer

A/B testing is the process of testing two or more different versions of your software with users to assess which performs better. It is a low-risk way of testing variations of a new or existing functionality. You can choose a part of your users to use feature A. The other group uses feature B. Then user feedback and response are evaluated using statistical testing to decide the final version of the feature. Typically, A/B testing is used to test the user experience of different interfaces. This allows the team to quickly gather feedback and test their initial hypothesis.

180

What steps do you take to stay updated with the latest testing methodologies, tools, and industry trends, and how do you apply this knowledge to your testing processes?

Reference answer

I regularly read testing blogs, attend webinars, and participate in workshops to keep my skills up-to-date and incorporate new approaches into my testing practices.

181

What is alpha testing?

Reference answer

Before you ship the software to the customers, the internal testing team performs alpha testing. Alpha testing is part of the user acceptance testing. Its goal is to identify bugs before the customers start using the software.

182

How do you handle conflicting priorities when managing multiple testing projects?

Reference answer

When managing conflicting priorities, I focus on clear communication, organization, and flexibility. I start by evaluating the criticality and urgency of each project, then create a schedule that allocates time and resources accordingly.

183

Can you describe your experience with Agile software development methodologies?

Reference answer

I have experience working in Agile environments, including Scrum and Kanban methodologies. I have participated in sprint planning, daily stand-up meetings, and retrospectives. I understand the importance of collaboration, frequent delivery, and continuous improvement in Agile software development.

184

How do you determine test coverage? What percentage is enough?

Reference answer

Coverage metrics can be misleading. A hundred percent code coverage looks great but doesn't guarantee quality. A line of code that gets hit might not cover all the branches it could take. What matters more is what you're covering. I focus on risk-based coverage: high-risk features like payment processing get thorough testing. Lower-risk features like styling details don't need as much attention. I also think about feature coverage—are the core user journeys tested? I aim for something like: the most critical features at 90%+ coverage, standard features at 70-80%, and nice-to-have features at 50%. That's usually enough to ship with confidence while being realistic about time constraints. I'll also look at past bugs: if a certain area has had lots of issues, I'll test it more thoroughly. The percentage is less important than being intentional about why you're testing what you're testing.

185

What are some of the most common testing mistakes that result in major issues?

Reference answer

Some of the most common mistakes that happen in Software Testing include: - Poor scheduling - Ignoring processes - Misallocation of resources - Turning a blind eye to small issues - Having unorganised documentation - Lack of communication Although these may not seem significant, these small mistakes can lead to major issues down the line. It's important to understand what impact errors can have on product quality and release time.

186

What are the key components of a test strategy?

Reference answer

A strong test strategy includes several critical components: objectives, scope, resources, testing environment, types of testing to be performed, tools and technologies, risks, and a clear timeline.

187

What is the importance of a test strategy?

Reference answer

A test strategy is a high-level document that outlines the approach and objectives of the testing process, providing a roadmap for the entire testing lifecycle. It is essential for the following reasons: - Clarifies Testing Objectives: The test strategy provides a clear understanding of the goals of testing, including which features and functionalities will be tested, the scope of testing, and what success looks like. - Guides the Team: It serves as a blueprint for all team members involved in the project, ensuring that everyone has a shared understanding of how testing will be conducted, what tools and techniques will be used, and what the timeline looks like. - Ensures Consistency: By defining testing standards, approaches, and processes, a test strategy ensures that testing is done consistently across all stages of the software development lifecycle. - Risk Mitigation: It helps in identifying potential risks, such as tight timelines, limited resources, or uncertain requirements, and recommends ways to mitigate these risks. - Facilitates Resource Allocation: A good test strategy helps allocate the necessary resources, including human resources, hardware, and software tools, ensuring that the testing process runs smoothly. - Quality Assurance: The test strategy ensures that the testing approach aligns with the project's overall quality goals and business objectives, and sets expectations for the level of quality to be achieved. The test strategy typically includes sections on test objectives, scope, testing types (manual, automated), resource requirements, risk assessment, tools, and timelines.

188

Advantages of manual testing?

Reference answer

Manual testing offers several advantages:Flexibility: Testers can easily adapt to changes in requirements and execute tests without waiting for automation scripts to be updated. Human Insight: Manual testing allows testers to use their intuition and experience to identify defects that automated scripts might miss. Exploratory Testing: It is well-suited for exploratory testing, where testers navigate through the application to uncover unexpected issues. Cost-Effective for Short-Term Projects: For small-scale or short-term projects, manual testing can be more cost-effective than investing in automation tools and scripts. Usability Testing: Manual testing is essential for evaluating the user experience and interface.

Security testing is a process to determine whether the system protects data and maintains functionality as intended.

191

What challenges have you faced in automation testing?

Reference answer

Automation testing can be challenging at times. For me, handling flaky tests and ensuring alignment with fast-paced development cycles are the top challenges. Handling these challenges involves using reusable components, continuous refactoring, better framework design, and close collaboration with development teams to improve testability from the beginning.

192

What is Code coverage?

Reference answer

Code coverage is different from Test coverage. Code coverage is about unit testing practices that must target all areas of the code at least once. It is usually done by developers or unit testers.

193

How do you ensure that test cases are comprehensive and cover all possible scenarios?

Reference answer

It's impossible to cover every scenario, but testers should aim to expand beyond the happy path, which tests the system under ideal conditions. In addition to standard cases, testers should include edge cases and negative scenarios, such as unusual inputs, unexpected user behavior, and invalid data. These areas are more likely to expose vulnerabilities that can improve overall test coverage.

194

What is HotFix?

Reference answer

A hotfix is a build aimed at resolving a severe issue found in production. At times, a build executed in the production evironment would have some critical errors and it would be rolled back. Now development team kept all their work aside and focus on fixing these errors immediately and release a new build to fix that in the production. This build is referred as a hotfix. Patches and hotfixes are two distinct types of software updates. Patches are available to the public, while hotfixes are not. Hotfixes are also known as quick-fix engineering updates (QFE updates)

195

What are some common challenges in test automation, and how do you overcome them?

Reference answer

Challenges include test maintenance, dynamic UI elements, and selecting appropriate test tools. Overcoming them involves robust scripting practices and regularly updating test scripts.

196

What testing methodologies are you familiar with?

Reference answer

I am familiar with both manual and automated testing methodologies. For instance, I use manual testing for exploratory testing when the user experience is critical, while I prefer automated testing for regression tests to save time and ensure consistency. In my last internship at a software company, I utilized Selenium for automated tests while performing manual tests for user interface components. Choosing the right methodology depends on the project's complexity and timeline.

197

What is performance testing?

Reference answer

Performance testing evaluates a system's responsiveness, scalability, stability, and speed under different workload conditions. It determines how the application behaves under normal and peak load, such as high traffic, large data volumes, or concurrent user interactions. The results help identify bottlenecks, optimize performance, and improve overall user experience.

198

How do you measure automation effectiveness?

Reference answer

Through failure rates, execution time, and defect detection.

199

You are assigned to test a web application that supports multiple languages. What aspects would you focus on?

Reference answer

Language and Localization Testing: - Verify the accuracy of translations for UI elements, notifications, and messages. - Test right-to-left (RTL) languages like Arabic. - Currency and Date Formats: - Validate currency symbols, number formats, and date displays for different regions. - Content Truncation: - Ensure longer translations do not overlap or break UI components. - Switching Languages: - Test seamless switching between languages without data loss or errors. - Cultural Sensitivity: - Verify that icons, colors, and content adhere to cultural norms.

200

How do you handle incomplete or unclear requirements?

Reference answer

Handling incomplete or unclear requirements is a common challenge in software testing. Here are several steps you can take to manage such situations: - Clarify with Stakeholders: The first step is to reach out to product owners, business analysts, or developers to clarify the unclear or missing requirements. Engaging directly with stakeholders can provide valuable context and clear up ambiguities. - Document Assumptions: If the requirements cannot be fully clarified, document any assumptions made in your test plan. This ensures transparency and helps stakeholders understand the basis of the tests. - Prioritize and Decompose: Break down the unclear requirements into smaller, more manageable parts and prioritize them. This can help you focus on the most critical parts of the software while waiting for further clarification. - Use Exploratory Testing: In cases where requirements are vague, exploratory testing can be helpful. It allows testers to actively explore the application and uncover issues even without complete requirements. - Feedback Loops: Establish a continuous feedback loop with developers and stakeholders. As testing progresses, unclear areas can be revisited, refined, and clarified based on testing insights. - Risk-Based Testing: Focus on high-risk areas of the application or functionalities that are critical to the business. Incomplete or unclear requirements are less impactful if testing concentrates on the most important aspects. By handling unclear or incomplete requirements with proactive communication, documentation, and testing strategies, QA teams can minimize the impact on the testing process and ensure software quality.
