Difference between Smoke Testing and Regression Testing
What is Smoke testing?
The testing method determines the stability of a deployed software build. It provides a sort of confirmation to the QA team to carry on with different levels of testing. A minimal set of tests are run on each build to test software functionalities. This testing method ensures that there are no show-stoppers in the build during the testing process. It is also known as “Build verification testing.”
What is Regression testing?
It is a testing method that ensures the new changes introduced in the code do not alter or modify theexisting functionalities ofa software application. Already executedtest casesare partially orfully selected and then re-executed to ensure that the existing functionalities are working as expected. The objective is to ensure that the existing functionalities are working fine despite making changes oradding new featuresto thecode.
Following are the differences between smoke testing and regression testing:
Smoke testing Regression testing
In simple terms, smoke testing meaning it verifies the crucial features and build the stability
Regression testing includes the test cases of a smoke test and covers only the core functionalities
Developers and testers are responsible for performing smoketests
The cost involved in conducting the testing is relatively low
The testing process is conducted quickly to confirm whethertoreject oraccept abuild
It is a surface-level testing where the system’s stability isverified
This testing method is always followed by a regressiontest
Basically, software regression testing ensures that the change hasn’t affected any existing functionality
The test cases are obtained from Software Requirement Specification (SRS) or functional specification
Testers are responsible for performing regressiontests
The cost involved in conducting the testing is quitehigh
Regression tests are not accountable for rejecting oraccepting abuild
It is a deep-level testing where the system’s rationality isverified
Thistesting method isperformedthroughout the testing phase
Thistesting methodisscriptedordocumented This testing method is neither scripted nor documented
There is not much effort, resources, and time requiredtoconduct thetesting
It is an acceptance type of testing where the build is validated so that further testing is prevented If it doesn’t pass
There is a lot of effort, time, and resources requiredtoconduct thetesting.
It is not an acceptance type of testing, and the functionalities aretested.
