Sanity testing is a type of software testing executed on the stable build of an application with minor code changes. It is also known as surface-level testing. A sanity test is performed to ensure the application works as expected after the bug fixes or changes in the code.
In the Software Development Life Cycle, software testing is an integral part of ensuring the performance of the software application. It is performed to find any bug or error that could lead to the failure of the software application. Such failure could be costly for the organization as it could not provide the expected user experience. Hence, it is suggested to check everything before the release of the software application in the market.
