API Testing

At its most basic level, API testing is intended to reveal bugs: inconsistencies or deviations from the expected behaviour. Continuous testing is also very important to make sure it continues to work when the public has access to it. The risk of putting a bad, and potentially insecure, product on the market is greater than the cost to test it.

API testing is one of the most challenging parts of the chain of software and QA testing because it works to assure that our digital lives run in an increasingly seamless and efficient manner. While developers tend to test only the functionalities they are working on, testers are in charge of testing both individual functionalities and a series or chain of functionalities, discovering how they work together from end to end.

APIs are what gives value to an application. It’s what makes our phones “smart”, and it’s what streamlines business processes. If an API doesn’t work efficiently and effectively, it will never be adopted, regardless if it is a free or not. Also, if an API breaks because errors weren’t detected, there is the threat of not only breaking a single application, but an entire chain of business processes hinged to it.
