Sanity testing is a narrow and focused testing to ensure basic functionality, while smoke testing is a broader and shallow testing to check major functionalities.

Smoke testing is performed to verify if the major functionalities of the software are working fine.
Sanity testing is a subset of regression testing, focusing on specific areas of the software.
Smoke testing is a subset of acceptance testing, ensuring the software is stable enough for further testing.
Sanity testing is usually performed by testers, while smoke testing can be performed by both developers and testers.
