    How do you test an API?

    Best Practices of API Testing:
  • Test cases should be grouped by test category.
  • On top of each test, you should include the declarations of the APIs being called.
  • Parameters selection should be explicitly mentioned in the test case itself.
  • Prioritize API function calls so that it will be easy for testers to test.
