I’m not entirely sure whether or not Runscope’s excellently useful Hurl.it is still operational, but if not, then Rigor has a great alternative lined up in the form of the aptly (but not quite as cleverly) named API Tester.
Built on top of the same platform as Rigor’s commercial API monitoring product, API Tester is a quick and simple way to make HTTP requests to and extract values from your hosted API scripts. In addition to this, this nicely laid out tool allows you to also assert whether response values are correct, reuse variables across steps, or inject custom logic using JavaScript.
So basically a quick way of building a multi-step test to validate an endpoint or even a suite of tests to traipse through all your back end services. Well made, useful little tool then.
