regression testing (redirected from Treegression)

regression testing

In software development, testing a program that has been modified in order to ensure that additional bugs have not been introduced. When a program is enhanced, testing is often done only on the new features. However, adding source code to a program often introduces errors in other routines, and many of the old and stable functions must be retested along with the new ones. Regression testing is one of the most important aspects of software testing and is often overlooked or given scant attention.

regression testing - Part of the test phase of software development where, as new modules are integrated into the system and the added functionality is tested, previously tested functionality is re-tested to assure that no new module has corrupted the system.
