How to do API testing?
API testing should cover at least the following testing methods 
in addition to the normal process:
• Discovery testing
• Usability testing
• Security Tests
• Test Automation
• Documentation
Discovery testing
The testing group should manually make a series of recorded calls to the API, for example, to 
verify that the specific resource published by the API can be correctly listed, created, and 
deleted.
Usability testing
These tests ensure that the API is functional and user-friendly. Can the API integrate well 
with other platforms?
Security Tests
These tests include the type of authentication required and whether sensitive data is 
encrypted with HTTP or both.
Automation Testing
API testing should ultimately create a set of scripts or tools that can be used to run the 
API on a regular basis.
Documentation
The testing team should ensure that the documentation is appropriate and provides enough 
information to interact with the API. The document must be part of the final testing.
List of API Testing Challenges
API testing challenges are:
• Since there is no GUI available to test the application, entering values becomes difficult.
• Validating and validating outputs on various systems is not difficult for testers.
• Have testers understand parameter selection and classification
• You should test your exception handling function.
• Testers need coding knowledge.
