Regression Testing:
"It is a type of testing in which one will perform testing on already tested functionality again and again."
Usually we can do it in two scenarios
1. When ever raised the defects to developers team and next build is released to testing department..we will test the defect functionality as well as the related functionalities once again.
2.When ever some new features are added to the application, and next build is released, then all the related features of those new features will be tested once again
Even random functionality testing also falls under Regression testing..
Note : Regression Testing starts from 2nd build and continues up to the last build.
But where in Retesting :
Here one will perform testing on the same functionality again and again with multiple sets of values in order to come to a conclusion whether it is working fine or not.
Resting will start from 1st build and continues up to the last build.
