Was ist regression test?

Regression testing is a type of software testing that aims to ensure that new code changes do not negatively impact the existing functionality of the software. It involves re-running test cases that have previously been executed to check if any new bugs have been introduced or if any existing defects have resurfaced.

Regression testing is typically performed after new features have been added, bugs have been fixed, or code has been refactored. The goal is to confirm that the changes have not introduced any new issues and that the software continues to function as expected.

Regression testing can be carried out manually or automated using testing tools. Automated regression testing is often preferred as it saves time and resources and allows for more thorough testing of the software.

Some common techniques used in regression testing include re-execution of test cases, prioritization of test cases based on risk, and selective regression testing to focus on areas that are most likely to be affected by changes.

Overall, regression testing is an important part of the software development process as it helps maintain the quality and stability of the software over time.
