Question { Wipro, 25525 }

Difference between re testing and regression testing, smoke
and sanity testing

Answer

In re testing we will test the application once again by
giving different input data.
In regression testing we will test the new build and we will
also test the dependent functionality.
Smoke testing is done before the deployment of application
into test environment here they will test the basic
functionality of the application.
Sanity test is the first test conducted by the tester to
validate the basic functions are working as per the
requirement or not. If sanity testing fails we cannot
cotinue testing.
