After a change is applied, the program is retested in selected areas to detect whether the change created new bugs or issues, or if the actual change achieved its intended purpose. Regression Testing refers to an in depth and through examination of software to ensure that recent code change has not adversely affected the existing features. Before applying a change, a program is tested. Sanity checks help to optimize testing time. Especially when you are dealing with systems that have serious impacts on customers. In my experience, you should conduct regression on a per sprint (generally two weeks) basis. Similar to smoke tests, regression tests should be implemented often, with every new build. 1.

Smoke tests are executed on the availability of the newly developed builds. Smoke Testing is the Surface Level Testing to verify stability of system. Unit Testing. Sanity check takes place after smoke testing, when the software build is already stable, and before regression when the QA team checks everything. Smoke Test is always followed by Regression Test. Sanity Testing Sanity testing is a software testing technique in which a particular functionality of the software is verified for its correctness instead of performing regression on the complete build. Means it is the verification of changes in software after bug fixes or changes in requirement.
