Over the last several years, REST APIs have swept the web development community, from indie shops to large companies. While we're getting better at creating these APIs, they definitely come with their own set of challenges. One of these challenges is testing.
When creating REST APIs, it's important to make sure the data and functionality produced by the application are correct. On top of that, we also have to make sure we are following the HTTP protocol and returning the right status codes, headers, and a slew of other pieces of data. This puts a lot of pressure on testing, and doing it all manually is a time-consuming challenge. It's much better to use an automated tool. In this Coffee Break Course, Derek Jensen will show you how to use a great tool for just this task: Postman.
