Automate API Testing—No Coding Required [VIDEOS]

Gartner, Forrester, and other industry experts are now advocating that API/message layer testing (services, message queues, database abstraction layers, etc.) is much more suitable for test automation and continuous testing than GUI testing—particularly with Agile and DevOps.

According to Wikipedia's Continuous Testing and API Testing pages, it's necessary to shift focus from GUI testing to API testing because:

  • APIs (the "transaction layer") are considered the most stable interface to the system under test.
  • GUI tests can't sufficiently verify functional paths and back-end APIs/services associated with multitier architectures. 
  • GUI tests require considerable rework to keep pace with the frequent changes typical of accelerated release processes; tests at the API layer are less brittle and easier to maintain.
  • Agile and DevOps teams working with short iterations and fast feedback loops find that GUI tests require considerable rework to keep pace with frequent change. Tests at the API layer are less brittle and easier to maintain.

Fortunately for software testers, API testing can be quite painless. We've prepared some short videos to help you understand what's involved and see how easy it is to get started with API testing...
