Without testing the APIs themselves, developers and testers would be stuck waiting for the entire application stack to be assembled before they can run the test.
API testing is a type of software testing, including direct API testing, and also as a part of integration testing to check whether the API meets the application's functional, reliability, performance, and security expectations.
API testing focuses on analyzing business logic and protecting applications and responding to data requests.
The testing API differs from other types of software tests in that a graphical user interface is not available, however, you need to set up a source environment that calls the API with the required parameters and validates the test result.
Get to know us more at https://www.fleekitsolutions.com/ API testing, by comparison to UI testing, can typically save up to eight hours - allowing developers to release products faster - confirms that the performance, functionality, security, and reliability of the application are working as expected - Our QA engineers can help your team through the API testing process to ensure that your software application is deployed to a production environment successfully every time.
When testing APIs, test cases for each endpoint or group of endpoints that are intended to work together (ie functional flow such as logon) can be developed to ensure that the API works as expected for possible known input configurations.
