Smoke Testing vs Sanity Testing in QA Testing

Smoke testing and sanity testing are both essential testing techniques in QA testing, but they serve different purposes.

Smoke Testing:

Smoke testing, also known as build verification testing, is performed to check if the critical functionalities of the software are working fine after each build. It is a preliminary test conducted to ensure that the software is stable enough for further testing.

Sanity Testing:

Sanity testing is a subset of regression testing and focuses on testing specific functionalities to ensure that new functionality or bug fixes have not adversely affected the existing functionalities of the software. It is performed after smoke testing to verify the sanity of the application.

Differences:

• Smoke testing is performed to check the stability of the system after each build, while sanity testing is conducted to ensure the sanity of specific functionalities.
• Smoke testing is a high-level test, while sanity testing is a focused test.
• Smoke testing is a subset of acceptance testing, while sanity testing is a subset of regression testing.
