Different between smoke and sanity testing?

Question

Accepted Answer

Smoke testing is a subset of regression testing, while sanity testing is a subset of acceptance testing.

Smoke testing is done to check if the software build is stable enough for further testing.
Sanity testing is done to check if specific functionalities are working correctly after changes.
Smoke testing is usually done before sanity testing.
Smoke testing is a shallow and wide approach, while sanity testing is a deep and narrow approach.
Example: Smoke testing may involve checking if the application launches without crashing, while sanity testing may involve checking if a specific feature like login functionality works after a code change.
