1. What is Agile Testing?

Agile Testing is a software testing process that follows the principles of Agile development. Unlike the traditional testing process, testing in Agile is integrated into the development cycle and conducted continuously to ensure quality. It emphasizes collaboration, flexibility, and rapid feedback, allowing teams to adapt to changing requirements quickly.

2. How is Agile Testing different from traditional testing?

Agile Testing focuses on early defect detection, continuous testing, and collaboration with stakeholders. Traditional testing often happens after the development phase, while Agile Testing occurs throughout the development lifecycle. Agile Testing also prioritizes working software over comprehensive documentation, unlike traditional methods.

3. What are the principles of Agile Testing?

Key principles include:

• Continuous feedback.
• Delivering working software frequently.
• Involving cross-functional teams.
• Emphasizing customer satisfaction.
• Encouraging simplicity and adaptability.

4. Explain the role of a tester in an Agile team.

In Agile, a tester is an integral part of the development team. They:

• Collaborate with developers and product owners to define acceptance criteria.
• Conduct exploratory and automated testing.
• Provide feedback on product quality.
• Ensure that testing aligns with user stories and sprint goals.

5. What are user stories, and how are they used in Agile Testing?

User stories are short, simple descriptions of a feature from the end-user perspective. Testers use them to derive test cases and acceptance criteria, ensuring that the delivered functionality meets user expectations.

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

TDD is a software development approach where test cases are written before the actual code. In TDD:

1. Write a test case.
2. Run the test and ensure it fails (as no code has been written yet).
3. Write the minimum code to make the test pass.
4. Refactor the code while keeping the test passing.

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

BDD extends TDD by writing test cases in a natural language that non-technical stakeholders can understand. It uses tools like Cucumber and SpecFlow, focusing on defining behaviors of the system rather than specific implementations.

8. What tools are commonly used in Agile Testing?

Popular Agile Testing tools include:

• Automation Testing: Selenium, Appium.
• Test Management: JIRA, TestRail.
• Continuous Integration/Continuous Deployment (CI/CD): Jenkins, CircleCI.
• BDD Tools: Cucumber, SpecFlow.

9. What is the Agile Testing Quadrant?

The Agile Testing Quadrant categorizes testing into four types:

1. Q1: Technology-facing tests that support the team (unit tests).
2. Q2: Business-facing tests that support the team (functional tests).
3. Q3: Business-facing tests that critique the product (user acceptance tests).
4. Q4: Technology-facing tests that critique the product (performance and security tests).

10. What is the purpose of continuous integration in Agile?

Continuous Integration (CI) ensures that code changes are automatically tested and integrated into the main codebase. Benefits include:

• Early detection of defects.
• Reduced integration risk.
• Faster delivery of working software.

11. What is a sprint, and how does it relate to Agile Testing?

A sprint is a time-boxed iteration in Agile where specific work items are completed. Agile Testing is performed continuously during the sprint to validate the functionality delivered in that iteration.

12. What is Exploratory Testing, and why is it important in Agile?

Exploratory Testing involves simultaneous learning, test design, and execution. It’s crucial in Agile as it allows testers to:

• Quickly adapt to changes.
• Identify edge cases and unexpected issues.
• Provide rapid feedback.

13. What are acceptance criteria, and why are they important?

Acceptance criteria are predefined conditions a software product must satisfy to be accepted by stakeholders. They guide testers in understanding what to validate and ensure alignment with user expectations.

14. What is the role of automation in Agile Testing?

Automation accelerates testing by enabling repetitive tasks to be performed quickly and accurately. In Agile, automation supports:

• Regression testing.
• CI/CD pipelines.
• Consistent feedback loops.

15. What challenges might you face in Agile Testing?

Common challenges include:

• Evolving requirements.
• Short development cycles.
• Limited documentation.
• Dependency on continuous collaboration.

16. What is the difference between ‘done’ and ‘done-done’ in Agile?

‘Done’ indicates that a feature is completed from a development perspective. ‘Done-done’ signifies that the feature has been developed, tested, reviewed, and is ready for release.

17. How do you handle changing requirements in Agile Testing?

Changing requirements are managed through:

• Close collaboration with stakeholders.
• Maintaining flexibility in test planning.
• Using exploratory and risk-based testing techniques.

18. What is a burndown chart, and how is it useful?

A burndown chart visualizes the amount of work remaining in a sprint. It helps teams track progress and identify if they are on track to meet their goals.

19. What is pair testing?

Pair testing involves two team members, often a developer and a tester, working together on the same testing activity. This collaboration enhances creativity, identifies defects early, and improves communication.

20. What are the benefits of Agile Testing?

Key benefits include:

• Faster defect detection and resolution.
• Enhanced collaboration between teams.
• Improved product quality and user satisfaction.

21. What is a spike in Agile?

A spike is a time-boxed activity to explore a specific problem or solution. Testers may use spikes to investigate testing strategies, tools, or complex scenarios.

22. How do you prioritize testing tasks in Agile?

Testing tasks are prioritized based on:

• Business value.
• Risk.
• Dependencies.
• Sprint goals.

23. What is regression testing in Agile?

Regression testing ensures that new changes do not adversely affect existing functionality. It’s performed frequently due to Agile’s iterative nature.

24. What is the role of a product owner in Agile Testing?

The product owner defines acceptance criteria, prioritizes the backlog, and provides feedback on testing outcomes to ensure the product meets business needs.

25. How do you ensure test coverage in Agile?

Ensuring test coverage involves:

• Writing tests for all acceptance criteria.
• Using automated tests for regression.
• Conducting exploratory testing for edge cases.

26. What is the velocity in Agile?

Velocity measures the amount of work a team completes during a sprint. It helps predict the team’s capacity for future iterations.

27. What are the types of testing commonly used in Agile?

Common types include:

• Unit testing.
• Integration testing.
• Functional testing.
• Regression testing.
• Performance testing.
• Security testing.

28. What is the role of feedback in Agile Testing?

Feedback ensures that testing aligns with user expectations and requirements. It helps improve product quality and enables continuous improvement.

29. What is the ‘Definition of Ready’ in Agile?

The Definition of Ready (DoR) is a checklist that ensures a user story is sufficiently detailed and understood before work begins. It helps improve productivity and reduce rework.

30. How do you measure the success of Agile Testing?

Success is measured by:

• Meeting sprint goals.
• Low defect leakage rates.
• High team collaboration and satisfaction.
• Delivering a high-quality product on time.
