What is the name of the testing that determines if a change caused issues in unchanged parts of the system?

• A. Compatibility Testing
• B. Regression Testing
• C. Artifact Testing
• D. Beta Testing

Answer: (B)

Regression testing is essential in software development and IT security to ensure that recent changes, such as updates or bug fixes, do not negatively affect the existing functionality of the system. This type of testing focuses on verifying that previously developed and tested software still performs after a change has been made. The objective of regression testing is to identify any unintended side effects caused by modifications, thus providing confidence that the system remains stable and operational. This process typically involves re-running previously completed tests, particularly those that could be impacted by the modifications. In contrast, compatibility testing focuses on determining how well the software performs in different environments, such as various hardware configurations or operating systems, to ensure it can operate in diverse situations. Artifact testing, on the other hand, generally refers to evaluating the outputs of development processes, while beta testing involves releasing a version of software to a limited audience outside the development team to gather feedback on its performance and functionality. Therefore, regression testing is the most appropriate term when discussing testing that checks for issues resulting from changes in software.
