What is a Regression Suite?
A regression suite is a collection of test cases that are executed to verify that recent changes or enhancements in software do not adversely affect the existing functionalities. In the context of Functional Testing, the regression suite focuses on ensuring that new code does not introduce new bugs in previously tested features. This is crucial during Software Testing as it helps in maintaining the integrity of the application as it evolves.
Typically, a regression suite includes both automated and manual test cases. Automated tests are particularly beneficial because they can quickly execute the same tests across different builds, saving time and minimizing human error. Manual tests may be included for areas requiring human discretion or complex verification.
The development of a regression suite often occurs after the initial software release and evolves over time with each software update. It is considered a best practice in Software Development to continuously add new test cases to the regression suite that cover newly developed features, thus ensuring comprehensive testing coverage.
In summary, a regression suite plays an essential role in ensuring the stability and reliability of software, making it a fundamental aspect of any effective testing strategy in the field of Technology.
