Regression Test Approach
When a particular problem is identified, the programs will be debugged and the fix will be done to the program. To make sure that the fix works, the program will be tested again for that criteria. Regression test will make sure that one fix does not create some other problems in that program or in any other interface. So, a set of related test cases may have to be repeated again, to make sure that nothing else is affected by a particular fix. How this is going to be carried out must be elaborated in this section. In some companies, whenever there is a fix in one unit, all unit test cases for that unit will be repeated, to achieve a higher level of quality.
