Sanity testing is a subset of regression testing, focusing on specific areas of the application to ensure they still work after changes.
Smoke testing is a preliminary testing to check if the build is stable enough for further testing, covering basic functionalities.
Sanity testing is usually performed after smoke testing to ensure critical functionalities are working properly.
Smoke testing is done to verify if the critical functionalities of the application are working fine.
