In quality assurance, sanity testing is a sort of regression testing. Sanity testing's major goal is to ensure that the proposed changes or functionality functions as planned. To save time and money, the testing team will reject the software product if the sanity test fails.
Sanity testing determines whether new module additions to an existing software build are stable enough to proceed to the next stage of testing. Also known as Surface Level Testing, this is required to quickly assess the quality of software regressions.
The main goal of sanity testing is to look for inaccurate results or problems that aren't present in component methods. Also, make certain that the newly introduced features do not interfere with the functionality of existing ones.
Sanity testing is a technique used by the test team to run some fundamental tests on software. Sanity testing is conducted after minor code or functionality modifications whenever a new build is obtained to ensure that bugs have been fixed. After extensive regression testing, sanity testing is performed.
Sanity checks are a crucial (though often overlooked) aspect of the data wrangling process. Because your final analysis is only as good as your data, it's well worth your time to double-check the accuracy and completeness of your data. A brief sanity check can help with correct analysis.
