100 Application Tester Interview Questions and Answers

  1. What is the difference between Verification and Validation?

    • Answer: Verification is the process of evaluating whether a software product is built according to the specification. Validation is the process of evaluating whether the software product meets the user's needs and expectations. Verification answers "Are we building the product right?", while validation answers "Are we building the right product?"

  2. Explain the different levels of testing.

    • Answer: Testing levels typically include Unit Testing (individual components), Integration Testing (combining modules), System Testing (testing the entire system), and Acceptance Testing (user acceptance testing).

  3. What is a test case? Give an example.

    • Answer: A test case is a set of conditions or variables under which a tester will determine whether an application is working correctly. Example: Test Case ID: TC_Login_001; Test Case Name: Verify successful login; Preconditions: User account exists; Steps: 1. Enter valid username, 2. Enter valid password, 3. Click Login button; Expected Result: User successfully logs in and navigates to the home page.

  4. What is a test plan?

    • Answer: A test plan is a document that outlines the objectives, scope, approach, and schedule of software testing activities. It guides the entire testing process.

  5. What are different types of software testing?

    • Answer: There are many types, including Functional Testing (testing features), Non-Functional Testing (performance, security, usability), Black Box Testing (without internal knowledge), White Box Testing (with internal knowledge), Regression Testing (testing after changes), and more.

  6. Explain the difference between Black Box and White Box testing.

    • Answer: Black box testing is done without knowledge of the internal code structure, focusing on inputs and outputs. White box testing involves examining the internal code structure and logic to design test cases.

  7. What is a bug report? What information should it contain?

    • Answer: A bug report is a formal document detailing a software defect. It should include: Summary, Steps to Reproduce, Expected Result, Actual Result, Severity, Priority, Environment details, Screenshots/Videos.

  8. What is Test Driven Development (TDD)?

    • Answer: TDD is a software development approach where test cases are written *before* the code is implemented. The code is then written to pass the tests.

  9. What is Agile testing?

    • Answer: Agile testing is a testing practice that aligns with the Agile software development principles. It emphasizes iterative development, close collaboration with developers, and continuous testing throughout the development lifecycle.

  10. What is the difference between Alpha and Beta testing?

    • Answer: Alpha testing is performed by internal users (e.g., developers, testers) within the organization. Beta testing is performed by external users (e.g., customers) in a real-world environment.

  11. Describe your experience with different testing tools.

    • Answer: [This answer should be tailored to your experience. Mention specific tools like Selenium, JMeter, Appium, TestRail, Jira, etc., and describe your proficiency with each.]

  12. How do you handle conflicts with developers?

    • Answer: I believe in open and respectful communication. I'd aim to understand their perspective, present my findings clearly and professionally, and collaboratively work towards a solution that ensures the quality of the software.

  13. How do you prioritize bugs?

    • Answer: I prioritize bugs based on severity and priority. Severity refers to the impact on the system, while priority indicates the urgency of fixing the bug. Critical bugs affecting core functionality are prioritized higher than minor cosmetic issues.

  14. Explain your experience with performance testing.

    • Answer: [This answer should be tailored to your experience. Mention tools used, types of performance tests conducted, and metrics analyzed (e.g., response time, throughput, resource utilization).]

  15. How do you ensure test coverage?

    • Answer: I use various techniques to ensure sufficient test coverage, including requirement traceability matrices, risk-based testing, and code coverage analysis tools. The goal is to test all critical functionalities and edge cases.

  16. How do you stay updated with the latest testing trends and technologies?

    • Answer: I regularly read industry blogs, attend conferences and webinars, participate in online communities, and pursue relevant certifications to stay abreast of current trends in software testing.

  17. Describe your experience with automation testing.

    • Answer: [This answer should be tailored to your experience. Mention specific automation frameworks, languages used, and the types of tests automated. Explain your approach to test automation, including the selection of tests to automate.]

  18. What are some common challenges you face as a tester?

    • Answer: Common challenges include tight deadlines, unclear requirements, insufficient test environments, managing a large number of bugs, and balancing automation with manual testing.

  19. How do you deal with incomplete or ambiguous requirements?

    • Answer: I clarify ambiguous requirements by proactively engaging with stakeholders, asking clarifying questions, and documenting my understanding to ensure everyone is on the same page. I would also identify potential risks and document them.
