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:
