One of the key points of developing the software is to ease the verification process, thus improving the quality of the system. For any change in the code, we should also be in a position to identify the impacted test cases and re-verify those sets of test cases, thus improving the predictability in the system. Writing the test case for the services is important for maintaining the quality and hygiene of the system.

There are multiple ways of testing the services. We will discuss two commonly used approaches—unit testing and integration testing.
