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?
4
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.
