This involes Application Programming Interfaces (APIs), that is, calling the API, getting output and then validating the response of the system. Therefore, using defined input parameters API is called. This test is used to test a collection of APIs that need to be tested as a system. Moreover, one of the biggest advantages we gain here is we do not need to rely on UI to be perfect to go ahead with the testing of the functionalities. We need API testing for the application which is consuming services from different application to show results. For instance, Price comparison websites.
Some of the advantages of API Testing are:
- Test for Core Functionality
- Access without UI
- Reduced costs
- Time efficiency
