Difference between smoke testing and sanity

Question

Accepted Answer

Smoke testing is a preliminary test to check if the software build is stable, while sanity testing is a subset of regression testing to verify specific functionalities.

Smoke testing is done to ensure the critical functionalities of the software are working fine after a build, while sanity testing is done to verify specific functionalities or components.
Smoke testing is a shallow and wide approach to testing, covering all major features, while sanity testing is a narrow and deep approach focusing on specific areas.
Smoke testing is usually performed before detailed testing, while sanity testing is performed after regression testing to ensure the specific changes made are working as expected.
Example: In a web application, smoke testing may involve checking if the login functionality works, while sanity testing may focus on verifying the search functionality after a code change.
