1. True or False: Regression tests should be run only when a critical bug is discovered.

Explanation

Regression tests should be run regularly, not just when a critical bug is found. They ensure that new code changes do not negatively impact existing functionality. Regular testing helps identify issues early in the development process, maintaining software quality and reliability throughout its lifecycle.

2. Which regression testing selection technique prioritizes high-risk areas?

Explanation

Risk-based selection focuses on identifying and prioritizing areas of the software that are most susceptible to failure or have the highest impact on the system. By concentrating testing efforts on these high-risk areas, this technique aims to optimize resource allocation and enhance the overall quality of the software while minimizing potential risks.

Submit

3. What is the main challenge of regression testing?

Explanation

Regression testing often involves re-running extensive test suites to ensure that new changes haven't introduced defects. The main challenge lies in managing these large suites effectively, as they can become time-consuming and resource-intensive, making it difficult to maintain test coverage while ensuring timely feedback on software quality.

Submit

4. True or False: Regression testing is only necessary for bug fixes, not feature additions.

Explanation

Regression testing is essential not only for bug fixes but also for feature additions. When new features are introduced, they can inadvertently affect existing functionality. Therefore, regression testing ensures that previously working parts of the software remain functional and that the new features integrate smoothly without introducing new issues.

Submit

5. Which tool is commonly used for automated regression testing in web applications?

Explanation

Selenium is a widely used open-source tool for automated testing of web applications. It allows testers to write scripts in various programming languages to simulate user interactions with the web interface, making it ideal for regression testing. Its ability to automate browser actions ensures consistent testing across different environments.

Submit

6. In regression testing, what does impact analysis help identify?

Explanation

Impact analysis in regression testing helps determine which test cases need to be executed based on recent code changes. By identifying affected areas, it ensures that testing efforts are focused on relevant parts of the application, thereby improving efficiency and effectiveness in validating that the changes do not introduce new defects.

Submit

7. True or False: Regression tests must be designed to verify only new functionality.

Submit

8. What is a key advantage of test case prioritization in regression testing?

Submit

9. Which practice ensures regression test effectiveness over time?

Submit

10. What is the primary objective of regression testing?

Explanation

Regression testing primarily aims to ensure that recent code modifications have not adversely affected the existing features of the software. By re-evaluating previously tested functionalities, it helps maintain software stability and reliability after updates or bug fixes. This process is crucial for delivering a seamless user experience and preserving the integrity of the application.

Submit

11. Which regression testing technique selects test cases based on code coverage?

Explanation

Coverage-based selection focuses on selecting test cases that ensure all parts of the code are tested. By analyzing code coverage metrics, this technique identifies which areas of the code have been executed by existing tests and targets those that require additional testing, thereby enhancing the effectiveness of regression testing.

Submit

12. True or False: Regression testing should only be performed after major code releases.

Explanation

Regression testing should be performed not only after major code releases but also after minor changes, bug fixes, or any updates to ensure that new code does not negatively impact existing functionality. Regular regression testing helps maintain software quality and stability throughout the development lifecycle.

Submit

13. What does RTS stand for in regression testing?

Explanation

Regression Test Selection refers to the process of identifying a subset of test cases to execute after changes in software, ensuring that existing functionalities remain unaffected. This approach optimizes testing efforts by focusing on relevant tests, thus improving efficiency and reducing the time and resources needed for regression testing.

Submit

14. Which of the following is a benefit of automated regression testing?

Explanation

Automated regression testing streamlines the testing process by allowing tests to be executed quickly and consistently. This efficiency reduces the time and resources required for repeated test executions, enabling teams to focus on more complex testing tasks and accelerating the overall development cycle.

Submit

15. In regression testing, what is a test suite?

Explanation

In regression testing, a test suite refers to a comprehensive set of test cases designed to evaluate the functionality of a software application. It ensures that new code changes do not adversely affect existing features, allowing for systematic verification and validation of the software's performance and reliability.
