2. Explain the difference between functional and non-functional testing.

Sample Answer:

Functional Testing

• Verifies the correctness of a software application’s functionality according to requirements.
• Focuses on testing individual features, modules, and the overall system behavior.
• Examples: Unit testing, integration testing, system testing

Non-Functional Testing

• Evaluates the performance, reliability, usability, security, and other non-functional aspects of the application.
• Focuses on ensuring that the application meets quality standards and user expectations.

3. Discuss the role of test automation in quality assurance.

Sample Answer:

• Speed and efficiency: Automates repetitive and time-consuming test cases, freeing up manual resources for more complex tasks.
• Consistency and accuracy: Executes test cases consistently, reducing human error and improving test coverage.
• Improved regression testing: Automates regression testing, ensuring that new features do not introduce defects into existing functionality.
• Data-driven testing: Allows for testing with multiple sets of data, expanding test coverage and scenarios.
• Continuous integration: Integrates automated testing into development pipelines, providing fast feedback and early defect detection.

4. Describe the principles of agile testing.

Sample Answer:

• Collaboration: Involves testers and developers throughout the development lifecycle.

• Collaboration with development team: Describe how you collaborate with developers to resolve defects and communicate updates.
• Quality metrics tracking: Explain how you use bug tracking tools to monitor quality metrics, such as defect density and time to resolution.

7. Explain the concept of equivalence partitioning and boundary value analysis.

Sample Answer:

Equivalence Partitioning

• Divides the input domain into equivalence classes where all values within a class are expected to behave similarly.
• One test case is designed to represent each equivalence class.

Boundary Value Analysis

• Focuses on testing the boundaries of input domains, including minimum, maximum, and extreme values.
