automation qa analyst Interview Questions and Answers

1. What is the difference between QA and testing?

   • Answer: QA (Quality Assurance) is a broader process encompassing all activities that ensure the quality of a software product throughout its lifecycle. Testing is a subset of QA, focusing specifically on verifying the software's functionality and identifying defects.

2. Explain the difference between black-box, white-box, and grey-box testing.

   • Answer: Black-box testing focuses on the functionality without knowing the internal code structure. White-box testing involves examining the internal code structure and logic. Grey-box testing combines elements of both, having partial knowledge of the internal workings.

3. What are the different levels of testing?

   • Answer: Common levels include unit testing (individual components), integration testing (interaction between components), system testing (entire system), acceptance testing (user validation), and regression testing (after code changes).

4. Describe the software development life cycle (SDLC) models you are familiar with.

   • Answer: Examples include Waterfall, Agile (Scrum, Kanban), DevOps, and Spiral. Each has different approaches to development and testing integration.

5. What is the difference between verification and validation?

   • Answer: Verification confirms that the software is being built correctly (following specifications). Validation confirms that the software is being built correctly (meeting requirements).

6. Explain different testing methodologies.

   • Answer: Examples include Agile testing, Waterfall testing, Model-Based Testing, Risk-Based Testing, and exploratory testing, each with its own approach to testing strategy and execution.

7. What are some common software testing types?

   • Answer: Functional testing (verifying features), performance testing (speed, scalability), security testing (vulnerabilities), usability testing (ease of use), compatibility testing (different browsers/devices).

8. What is Test-Driven Development (TDD)?

   • Answer: TDD is a software development approach where test cases are written *before* the code. This guides development and ensures testability.

9. What is Behavior-Driven Development (BDD)?

   • Answer: BDD is an extension of TDD that focuses on the behavior of the system from the perspective of the user or business stakeholder. It often uses tools like Cucumber.

10. What is a test plan? What does it include?

    • Answer: A test plan is a document detailing the scope, approach, resources, and schedule of software testing activities. It includes objectives, test strategy, test cases, timelines, and reporting procedures.

11. What is a test case? What are its key components?

    • Answer: A test case is a set of actions executed to verify a specific feature or functionality. Key components include test case ID, objective, steps, expected results, and actual results.

12. What is a test suite?

    • Answer: A test suite is a collection of related test cases organized for efficient execution.

13. What is a test script?

    • Answer: A test script is a set of instructions written in a scripting language (e.g., Python, JavaScript, Ruby) to automate the execution of test cases.

14. What is the difference between a bug and a defect?

    • Answer: The terms are often used interchangeably. A defect is a flaw in the software, while a bug is a defect that causes unexpected behavior. In essence, all bugs are defects, but not all defects are bugs.

15. What is a bug report/defect report? What information should it contain?

    • Answer: A bug report documents a software defect. It should include the steps to reproduce the issue, the expected behavior, the actual behavior, severity, priority, screenshots/logs, and environment details.
