When we perform sanity , smoke and regression testing

Question

Accepted Answer

Sanity, smoke, and regression testing are performed at different stages of software development to ensure quality and stability.

Sanity testing is performed after a small change or bug fix to ensure that the core functionality of the software is still intact.
Smoke testing is performed to check the basic functionality of the software after a build or release.
Regression testing is performed to ensure that the existing functionality of the software is not affected by new changes or updates.
Sanity and smoke testing are usually performed before regression testing.
Example: After fixing a critical bug, sanity testing is done to verify if the bug is resolved and the software is still functioning properly.
Example: Smoke testing is done before a major release to ensure that the basic features of the software are working as expected.
Example: Regression testing is done after adding new features to ensure that the existing functionality is not broken.
