Course details
How do you test your API to ensure it's working as intended and solving business problems? Most API testing doesn't actually test the API. In this course, Keith Casey teaches you how to test and validate your API by using behavior-driven development, or BDD, to test APIs via their external endpoints. Keith looks at the API from the consumer’s point of view, confirming that problems experienced by your end users are being solved. Join Keith in this course to learn how to prove that your APIs are working exactly as we expect today, tomorrow, and continuously.
