Smoke and Sanity testing help the QA team save time by quickly testing to make sure if an application is working properly or not. Also, it ensures that the product is eligible for further testing. Whereas Regression testing helps enhance the confidence about the software quality after a particular change. Especially, that the code changes are not affecting related areas.
Smoke Testing is done by both the dev team or by the QA team and can be taken as a subset of rigorous testing. Whereas both Sanity & Regression testing are done only by the QA team. Also, Sanity testing can be considered as a subset of acceptance testing.
Smoke testing is executed at the initial stage of SDLC, to check the core functionalities of an application. Whereas Sanity & Regression testing are done at the final stage of SDLC, to check the main functionalities of an application.
As per the requirement of testing & time availability, the QA team may have to execute Sanity, Smoke & Regression tests on their software build. In such cases, Smoke tests are executed first, followed by Sanity Testing & then based on time availability regression testing is planned.
In practice, all QA teams need to do Smoke, Sanity and Regression testing. All of these testing types have a pre-defined number of test cases that get executed multiple times. This repetitive execution also makes them an ideal candidate for test automation.
