Website Testing Interview Questions and Answers for 2 years experience

Website Testing Interview Questions & Answers
  1. What is the difference between Verification and Validation?

    • Answer: Verification checks if we are building the product right (following specifications), while validation checks if we are building the right product (meeting user needs and requirements).
  2. Explain the different types of software testing.

    • Answer: There are many types, including Unit, Integration, System, Acceptance (UAT), Regression, Functional, Non-functional (Performance, Security, Usability, etc.), Smoke, Sanity, and more. Each focuses on a different aspect of the software.
  3. What is the difference between black box testing and white box testing?

    • Answer: Black box testing is done without knowledge of the internal code, focusing on inputs and outputs. White box testing involves examining the internal code structure and logic.
  4. What is a test case? Provide an example.

    • Answer: A test case is a set of steps to test a specific functionality. Example: For a login form, a test case might be: 1. Enter correct username, 2. Enter correct password, 3. Click login, 4. Verify successful login and redirection to the home page.
  5. What is a test plan?

    • Answer: A test plan is a document that outlines the testing strategy, scope, objectives, schedule, resources, and deliverables for a software testing project.
  6. What is a test suite?

    • Answer: A test suite is a collection of test cases related to a specific module or feature.
  7. Explain the software development lifecycle (SDLC).

    • Answer: SDLC is a structured process for planning, creating, testing, and deploying software. Common models include Waterfall, Agile (Scrum, Kanban), and DevOps.
  8. What is Agile testing?

    • Answer: Agile testing is a testing approach that aligns with Agile development methodologies, emphasizing continuous testing, collaboration, and rapid feedback loops.
  9. What are the different levels of testing?

    • Answer: Unit, Integration, System, Acceptance (UAT).
  10. Describe your experience with bug reporting.

    • Answer: [Candidate should describe their process, including tools used, details included in bug reports (steps to reproduce, expected vs. actual results, screenshots, severity, priority), and communication with developers.]
  11. What is a bug life cycle?

    • Answer: The bug life cycle describes the stages a bug goes through, from its discovery to its resolution and closure. This typically includes stages like New, Assigned, Open, Resolved, Retest, Verified, Closed, and Reopened.
  12. What testing tools are you familiar with?

    • Answer: [Candidate should list tools they've used, e.g., Selenium, JMeter, Postman, Browser developer tools, etc. and briefly describe their experience with each.]
  13. How do you prioritize test cases?

    • Answer: Prioritization is based on risk, criticality, business impact, and dependencies. High-risk areas and critical functionalities are tested first.
  14. Explain the concept of test-driven development (TDD).

    • Answer: TDD involves writing tests *before* writing the code. The tests define the desired functionality, and the code is written to pass the tests.
  15. What is regression testing?

    • Answer: Regression testing is performed after code changes to ensure that new code hasn't introduced bugs or broken existing functionality.
  16. What is smoke testing?

    • Answer: Smoke testing is a preliminary test to verify that the critical functionalities of a build are working correctly before more extensive testing.
  17. What is sanity testing?

    • Answer: Sanity testing is a quick check to ensure that a specific functionality is working as expected after a minor code change or bug fix.
  18. What is performance testing? What are its different types?

    • Answer: Performance testing evaluates the responsiveness, stability, scalability, and resource usage of a website under various load conditions. Types include Load Testing, Stress Testing, Endurance Testing, Spike Testing.

    • Answer: The terms are often used interchangeably. A defect is a flaw in the software, while a bug is often a specific instance of that flaw that causes unexpected behavior.
  21. What is usability testing?

    • Answer: Usability testing evaluates how easy and user-friendly a website is for its intended users.
  22. How do you ensure test coverage?

    • Answer: Through careful planning and designing test cases that cover all aspects of the application, including various inputs, edge cases, and user scenarios. Tools can help track test coverage.
  23. What is security testing? What are some common vulnerabilities?

    • Answer: Security testing identifies vulnerabilities in a website to prevent unauthorized access or data breaches. Common vulnerabilities include SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF).
