Explain confirmation testing and regression testing

Question

Define the term confirmation testing and regression testing?

Answer 1

If we solve a fault in a present application we will use confirmation testing which is used to test that if the defect is removed or not. It's very likely that additional part of the application is affected because of this defect or changes to the application. Hence to make sure that no extra part of application is affected we could use regression testing.

Regression testing is applied for regression faults. Regression defects are the defects which occur while the functionality that was formerly working normally has stopped running. This is most likely because of alteration prepared in the program or the environment. To expose such type of defect regression testing is performed.
