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 the existing functionalities of a software application. Already executed test cases are partially or fully 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 or adding new features to the code.

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
the existing functionalities of a software application. Already executed test cases are partially or fully
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
or adding new features to the code.
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
Basically, software regression testing ensures that the change hasn’t affected any existing functionality
Regression testing includes the test cases of a
smoke test and covers only the core
functionalities
Requirement Specification (SRS) or functional
specification
performing smoke tests
regression tests
relatively low
quite high
confirm whether to reject or accept a build
Regression tests are not accountable for
rejecting or accepting a build
It is a surface-level testing where the system’s
stability is verified
rationality is verified
regression test
testing phase
This testing method is scripted or documented This testing method is neither scripted nor
documented
required to conduct the testing
There is a lot of effort, time, and resources
required to conduct the testing.
It is an acceptance type of testing where the
build is validated so that further testing is
prevented If it doesn’t pass
It is not an acceptance type of testing, and the
functionalities are tested.
