Postman in Chrome is a Wonderful Tool
I've been doing a little work on the Clojure CryptoQuip solver by adding a new RESTful endpoint for the server that takes the quip and the clue and solves the puzzle. It's not all that hard, but it's a POST call, as the body of the POST is JSON, and I needed a tool to hit my server to make sure that I had it all working. Enter Postman.
This is just an amazing tool for Chrome. It's a very singular task, and it does an excellent job of making sure that you can make all the calls you need with all the headers and arguments and get back what you need - and even keep a running history of all the calls to re-do should you need them.
Clearly the folks that wrote this knew what they needed and spent quite a bit of time on it. I have yet to find a hole, a bug, or a limitation. It's just good, solid working code. And it's free. Wow. Impressive.
I looked at several of the OS X tools on the App Store, and even on the web and the nice ones were more than $20, and most weren't nearly as nice as Postman. If you need something like this, you need it, and this is as good a tool for the job as you can get.
