agile qa tester Interview Questions and Answers

1. What is Agile methodology?

   • Answer: Agile is an iterative approach to software development emphasizing flexibility, collaboration, and customer satisfaction. It focuses on delivering working software in short cycles (sprints) rather than following a rigid plan.

2. Explain the Scrum framework.

   • Answer: Scrum is a popular Agile framework that uses short iterations called sprints (typically 2-4 weeks) to develop software. It involves roles like Product Owner, Scrum Master, and Development Team, and utilizes artifacts like Product Backlog, Sprint Backlog, and Increment.

3. What is the role of a QA tester in an Agile environment?

   • Answer: In Agile, QA testers are integrated into the development team, actively participating in sprint planning, daily stand-ups, and sprint reviews. They focus on continuous testing, providing immediate feedback, and ensuring quality throughout the development process.

4. How does Agile testing differ from traditional testing?

   • Answer: Agile testing is more collaborative and continuous, integrated throughout the development lifecycle, while traditional testing often happens in distinct phases. Agile emphasizes rapid feedback loops and adaptability, while traditional methods are more rigid and plan-driven.

5. What are some common Agile testing methodologies?

   • Answer: Some common Agile testing methodologies include Test-Driven Development (TDD), Behavior-Driven Development (BDD), Acceptance Test-Driven Development (ATDD), and Exploratory Testing.

6. Explain Test-Driven Development (TDD).

   • Answer: TDD is a development approach where tests are written *before* the code. This ensures that the code meets the requirements and helps in preventing bugs early in the development process.

7. Explain Behavior-Driven Development (BDD).

   • Answer: BDD focuses on defining software behavior from the perspective of stakeholders (customers, business analysts, etc.). It uses a shared language (e.g., Gherkin) to describe test cases, promoting better collaboration between developers, testers, and business stakeholders.

8. What is the difference between BDD and TDD?

   • Answer: While both BDD and TDD are Agile methodologies focusing on testing, TDD emphasizes technical aspects and unit testing, driven by developers. BDD focuses on business requirements and acceptance criteria, involving stakeholders and using a more human-readable language.

9. What is Exploratory Testing?

   • Answer: Exploratory testing is a simultaneous learning, test design, and test execution process. Testers learn about the software while testing it, adapting their approach based on their findings.

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