agile tester Interview Questions and Answers

1. What is Agile testing?

   • Answer: Agile testing is a software testing approach that aligns with the principles of agile software development. It emphasizes iterative development, close collaboration between testers and developers, continuous feedback, and adaptability to changing requirements. It's about testing throughout the development lifecycle, not just at the end.

2. Explain the difference between Agile and Waterfall testing.

   • Answer: Waterfall testing is a sequential process where testing happens after development is complete. Agile testing is iterative and integrated throughout the development process. Agile emphasizes continuous feedback and adaptation, while Waterfall follows a rigid, pre-planned sequence.

3. What are the key principles of Agile testing?

   • Answer: Key principles include continuous testing, close collaboration with developers, early and frequent feedback, customer involvement, adaptability to change, simplicity, and focus on delivering value.

4. What are some popular Agile methodologies?

5. Describe your experience with Scrum.

   • Answer: (This requires a personalized answer based on your experience. Example: "In my previous role, we used Scrum. I participated in daily stand-ups, sprint planning, sprint reviews, and sprint retrospectives. I was responsible for [specific tasks and contributions within the Scrum framework].")

6. What is a Sprint in Scrum?

   • Answer: A Sprint is a time-boxed iteration in Scrum, typically lasting 2-4 weeks, during which a potentially shippable product increment is created.

7. What is a Product Backlog?

   • Answer: The Product Backlog is an ordered list of all features, requirements, enhancements, and bug fixes that are needed for a product.

8. What is a Sprint Backlog?

   • Answer: The Sprint Backlog is the subset of the Product Backlog that the development team commits to completing during a specific Sprint.

9. What is the role of a tester in an Agile team?

   • Answer: The Agile tester is a collaborative team member responsible for ensuring quality throughout the development lifecycle. They actively participate in planning, testing, providing feedback, and collaborating with developers to identify and resolve defects quickly.

10. How do you handle changing requirements in an Agile project?

    • Answer: Agile embraces change. I would work with the Product Owner and the team to understand the impact of the changes, prioritize them, and adjust the Sprint backlog accordingly. I would also update the test cases and test plans to reflect the new requirements.

11. What testing techniques do you use in Agile?

    • Answer: (This requires a personalized answer. Example: "I utilize a variety of techniques including unit testing, integration testing, system testing, regression testing, user acceptance testing (UAT), exploratory testing, and test-driven development (TDD). The specific techniques used depend on the project and its needs.")

12. Explain Test-Driven Development (TDD).

    • Answer: TDD is a software development approach where test cases are written *before* the code. This ensures that the code meets the specified requirements and helps to catch bugs early in the development process.

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

    • Answer: BDD is an extension of TDD that emphasizes collaboration between developers, testers, and business stakeholders. It uses a common language (often Gherkin) to define acceptance criteria and ensures everyone understands the desired behavior of the software.

14. What is Acceptance Test-Driven Development (ATDD)?

    • Answer: ATDD is a collaborative approach where acceptance criteria are defined as tests *before* development starts. These tests serve as a contract between the development team and the stakeholders, ensuring that the software meets their expectations.

15. How do you prioritize testing activities in an Agile environment?

    • Answer: Prioritization is based on risk, business value, and dependencies. High-risk areas and features with the highest business value are tested first. Testing activities are aligned with the sprint goals and the overall product roadmap.

16. How do you manage defects in an Agile project?

    • Answer: Defects are tracked using a defect tracking system (e.g., Jira). They are prioritized, assigned to developers, and monitored for resolution. Regular communication with the development team ensures timely fixes and prevents regressions.

17. What metrics do you use to measure the success of Agile testing?

    • Answer: Metrics include defect density, defect escape rate, test coverage, sprint velocity, and customer satisfaction. These metrics help assess the effectiveness of the testing process and identify areas for improvement.

18. How do you handle conflicts with developers in an Agile team?

    • Answer: Conflicts are addressed through open communication and collaboration. I would try to understand the developer's perspective, find common ground, and work together to find a solution that benefits the team and the product.
