WHAT IS sanity testing? What is Smoke testing?

Question

Accepted Answer

Sanity testing is a narrow and focused testing to quickly determine if a new functionality is working as expected. Smoke testing is a preliminary testing to check if the software build is stable enough for further testing.

Sanity testing is a subset of regression testing and focuses on specific areas of the application.
It is usually performed after major changes in the code or functionality to quickly verify that the new changes have not adversely affected the existing functionality.
For example, after fixing a critical bug, sanity testing can be done to ensure that the bug fix did not introduce any new issues.
Smoke testing is a preliminary testing to check if the software build is stable enough for further testing.
It is performed before more in-depth testing to ensure that the basic functionalities of the software are working correctly.
For example, after receiving a new software build, smoke testing can be done to check if the main features are working before proceeding with detailed testing.
