  • What is regression testing?

    DEFINITION: Partial retesting of a modified program to make sure that no new errors were introduced while making changes to the code (developing new or fixing existing one)
    • should be done for each new release (build)
    • we do not have enough time to retest software completely. Risk analysis is involved when we decide on which parts should be tested (partial retesting)
    • second (to release acceptance) most frequently executed test
    • very good candidate for automation


    AVOID:
    - after fixing a bug
    - after new feature was added
    - making sure the bug was fixed
    - not about manual/automated or black/white box
