Regression Testing in Tessy

Regression testing is the repetitive running of already successfully completed test cases. The intention of regression testing is to verify that modifications and enhancements to a test object do not break the already successfully completed tests.

Regression testing should be done e.g. after:

• The test object was changed to remedy a failed test case.
• The test object was optimized, e.g. for speed, or for maintainability.
• Another version of the compiler is used.
• The test object was enhanced.

Tessy is especially well-suited for regression testing:

• Tessy can automatically adapt existing test cases to modified test objects.
• Tessy can run tests without user interaction (batch test).
• Tessy can restore test cases related to former software versions.
