Regression testing

Did a new build break an existing function? Repeat testing after changes for managing risk relate to product enhancement.

A regression test is performded when the tester wishes to see the progress of the testing processs by performing identical tests before and after a bug has been fixed. A regression test allows the tester to compare expeted test results with the actual results.

Regression testing's primary objective is to ensure that all bugfree features stay that way. In addition, bugs which have been fixed once should not turn up again in subsequent program versions.

Regression testing: After every software modification or before next release, we repeat all test cases to check if fixed bugs are not show up again and new and existing functions are all working correctly.

Regression testing is used to confirm that fixed bugs have, in fact, been fixed and that new bugs have not been introduced in the process, and that festures that were proven correctly functional are intact. Depending on the size of a project, cycles of regression testing may be perform once per milestone or once per build. Some bug regression testing may also be performed during each accceptance test cycle, forcusing on only the most important bugs. Regression tests can be automated.
