To put it simply, an API acts as a mediator between users (clients) and resources (servers). APIs allow users to work with the system to return their desired result. JS vs jQuery jQuery Selectors jQuery HTML jQuery CSS jQuery DOM Programs use an API to communicate, retrieve information, or perform a function.

Verify if the API triggers some other event or calls another API. ![]() Verify if the API's does not return anything. Return Value based on input condition - The return value from the API's are checked based on the input condition. Verifying the Sequence of API calls and check if the API's produce useful results from successive calls. Verifying the behaviour of the API which is considering the external environment conditions such as files, peripheral devices, and so forth. Generating more value added parameter combinations to verify the calls with two or more parameters. During Testing, a test of following things is looked at.Įxploring boundary conditions and ensuring that the test harness varies parameters of the API calls in ways that verify functionality and expose failures. The API Testing is performed for the system, which has a collection of API that ought to be tested. It consists of a set of routines, protocols and tools for building the software applications. ![]() API stands for Application Programming Interface, which specifies how one component should interact with the other.
