Retest is the process of checking whether the reported bugs are been fixed or not by the development team.
Purpose: To identify whether the given bugs /issues/ defects are fixed or not.
REGRESSION TESTING:
Regression Testing: Testing conducted for the purpose of evaluating whether or not a change to the system (all CM items) has introduced a new failure
Purpose: To identify whether on fixation of the issues / bugs / defects new issues get introduced into the system.
Thanks for the post on this mostly used topic. In my opinion:
ReplyDeleteRegression Testing is the execution of all or a select set of test cases which have passed on the previous build or release of the application under test in order to validate that the original features and functions are still working as they were previously. These tests normally will not have already been executed against the current build or release as normally only the new features and functions are tested prior to regression testing.
Retesting is the execution of one or a set of test cases which previously failed due to a suspected defect in the software which now is documented as being remedied.
