What is sanity and regression

Question

Accepted Answer

Sanity and regression testing are types of software testing used to ensure the stability and functionality of a product.

Sanity testing is a narrow and focused testing approach to quickly determine if the software is ready for further testing.
Regression testing is the process of retesting the unchanged parts of the software after modifications to ensure that no new bugs have been introduced.
Sanity testing is usually performed before regression testing to check critical functionalities.
Regression testing is more comprehensive and covers a wider range of test cases.
Examples: Sanity testing can include checking if the login functionality works after a new build. Regression testing can involve running all test cases after a code change to ensure no new bugs.
