suresh Explanation of Difference between Smoke Testing and Sanity Testing
Smoke testing and sanity testing are two crucial testing techniques in software testing, often used at different stages of the testing process. Here is a breakdown of the key differences between smoke testing and sanity testing:
- Smoke Testing:
- Sanity Testing:
Smoke testing, also known as build verification testing, is a preliminary round of testing conducted to check whether the software build is stable enough for more in-depth testing. It involves running a set of basic tests on the software after a new build or version is created to ensure that critical functionalities work correctly and the build is suitable for further testing. The main purpose of smoke testing is to identify major issues early in the development cycle.
Sanity testing, also called subset testing, is a focused and narrow regression testing technique that verifies specific sections of the software functionality after changes are made. It is performed on stable builds to ensure that the modifications have not affected the existing functionalities and features. The goal of sanity testing is to validate that the new features or changes introduced are working as expected without impacting the core functions of the software.
In summary, smoke testing is done to validate the stability of a new build, while sanity testing is performed to verify specific areas of functionality after modifications. Both testing techniques play distinct roles in ensuring the overall quality and reliability of the software product.
