Key considerations for API automation

Automating API tests involves a thorough understanding of the underlying business logic as well as the architectural nuances. Data and performance aspects of the API always pose a tough challenge when trying to run multiple iterations of API tests.

Effective API test automation

Let us now look at some chief considerations when automating API tests:

  • Static data references must be eliminated wherever possible. These render the tests inextensible and isolated.
  • Do more than happy path testing since API tests are quick to run and can provide feedback early in the product life cycle. Applicable product use cases should be tested to a greater extent via APIs. Consider mocking and stubbing to fill in gaps to complete the application flow.
