Types of Defects

Defects that are detected by the tester are classified into categories by the nature of the defect. The following are the classification

Showstopper (X): The impact of the defect is severe and the system cannot go into the production environment without resolving the defect since an interim solution may not be available.

Critical (C): The impact of the defect is severe, however an interim solution is available. The defect should not hinder the test process in any way.

Non critical (N): All defects that are not in the X or C category are deemed to be in the N category. These are also the defects that could potentially be resolved via documentation and user training. These can be Graphic User Interface (GUI) defects are some minor field level observations.
