Q:- Regression testing through manual or automation?
A:- Regression testing process definitely comes always under testing life cycle during further implementation. Regression process should never be missed after some updates/implementation and changes.
Regression testing can be performed by manually and automation techniques. Process takes so much time to perform regression through manual technique but it depends on “units” so there is no way to ignore completely manual technique but automation techniques should also be included there in flow to complete test cycle to save reputation tasks.
By using “automation technique” there is way to ignore passing the values time by time to verify the modules. We can use the test scripts what we have created previously. Scripts can be written before executing test cases or with some techniques written cases can be recorded after execution for saving further same execution times.
