What is Regression Testing ? Why do Regression Testing ?
Why all the testcase execuation in each time of Regression
testing ?

Answer Posted / meghana

Regression testing is to test the already tested
application when the developer modifies the code to check
whether the change of code has not created errors elsewhere
in the application.

Usually regression testing is done with automation tools.
Automating the regression testing is very time saving for
the organization.

Regression testing is perfomed for the older code to check
the application for errors. After that regression testing
is performed for the older and newer code together to test
for any errors.
