Pluses and Minuses of Retesting

Retesting slightly reminds regression testing but
still there is a set of differences between these
types of software quality checking. Retesting is
more like rechecking of the earlier reproducing
error. Hence its name.

• What Are the Goals of Retesting?
• Verification of specific bugs and mistakes.
• Confirmation for developers that the problem is
  really valid and reproducible.
• The whole module is checked in order to make sure
  in its correct operation.
• To assure of correct operation of a certain
  feature, system component or module or
  application.

• Like any other type of software testing,
  retesting possesses a range of advantages among
  which there are
• confirming the error removal
• improving the whole product quality
• quick verification
• installing the new environment is not required -
  the same data and conditions are used.
• But it is not so simple, one should not also
  forget about minuses of retesting.

5

• What Are the Disadvantages of Retesting?
• A new build is required for the fixed error
  verification.
• The test cases cannot be automated.
• Additional time is required for the failed test
  cases rechecking.
• The retesting test cases can be used only after
  the primary testing process was completed.

Retesting may be connected with any other type of
checking. Executing security testing, usability
control, performance testing, load checking or
compatibility testing, the specialist has
detected the bug. The developer has fixed this
bug. Thereafter, one should recheck whether
everything operates correctly and the error was
really removed.
