Sanity testing could also be a version of regression testing to form sure a specific section of the appliance remains working after a bug fix or a functionality improvement. this type of QA is different from smoke testing because it's usually focussed only on one or two functionalities whereas smoke testing is aimed toward all major functionalities. When the test fails, QA rejects the build and send it back to the developers for a fix.
Sanity testing doesn't use prewritten scripts and is usually done when a quick check is required to determine if the build is functional. A QA expert will identify the new features, functionality changes, or fixes then verify that the new implementation works needless to mention. The QA team also will confirm that the prevailing functionalities still work needless to mention. If the new and associated functional tests pass, the QA tester will approve the build as a pass.
Advantages:
The main advantage of sanity testing is that it reduces the time cost for detailed regression testing. because it's focused on a specific area, this type of QA provides a quick evaluation and minimizes unnecessary effort. this type of QA helps us to detect errors within the first stages of software development and helps minimize time wastage in development cycles. instead of expecting all of the testings to be completed, the developers depend on sanity testing to figure subsequent steps. If the test is successful, the event team can move onto the next task, and if the test fails the build goes back to the team for fixing. In most situations, regression testing follows a successful sanity test which goes to be used to identify additional bugs.
Challenges:
One of the difficulties of rational soundness testing is that it's consistently undocumented and unscripted then future references aren't conceivable. it would be difficult for a couple of testers, especially once they're a new therein project. this type of testing doesn't attend the design level of testing and it's difficult for the developer to identify and find a way to repair the problem. Also, sanity testing is concentrated only on certain functionalities which may miss issues with other functionalities.
Improvement:
To minimize the problems that arise because of testing not being scripted, an outsourced QA company can implement a simple way of documenting a sanity testing process. this may be done by creating a test run that uses a pool of existing test cases that can be derived from multiple modules. The results of these test cases are tracked to pass or fail the test, and this provides the developer and thus the tester a record of the testing that has been done.
