Answer / rahul

Regression testing is to test whether changed functinality
has not regressed,impacted anything in the existing
functionality

Approach for regression testing:

1. Carry out the impact analysis (Change and the impacted
areas around the change)

2. Select all the major test cases with the maximum
functional coverage. You may draw a traceability matrix to
identify the coverage.

3. Prepare a regression pack with the maximum test
coverage. 100% regression testing is ideally not possible.
Focus on the major functionality and impacted areas around
the change.

4. carry out the regression testing
