For the past few years, I've been trying to promote the idea that not every automation test should be a UI test, and have been focusing more on the types of tests that can be performed below the UI, like API testing. With the rise of the Internet of Things, this type of headless testing is only going to become more popular.

One of the tools I use all the time for REST-based API testing is rest-assured. In this episode, we’ll talk to the creator of the open-source tool’s REST-Assured, Power Mock and Awaitility, Johan Haleby.
