Continuous testing is very important to make sure that the incremental software product works as per the requirements and nothing gets broken. In many of the organizations, the user interface is formed quite late for testing through the user interface and hence product testing comes quite late during the SDLC. The risk of putting a bad,
and potentially insecure, product on the market is greater than the cost to test it.
Hence API testing is one of the best mechanism for the quick turnaround and providing the feedback to the developers on their code. A bad product released to the end users is catastrophic. API testing is one of the most challenging parts of the chain of software because QA team has to create an interface or framework to test both individual functionalities and a series or chain of functionalities, discovering how they work together from end
to end. It is essential to test the APIs to make sure that:
It is doing what it is expected to do
It is able to sustain the load
It is able to recover in all types of weird interations done by the users
It works across devices, browsers, and operating systems
