Face it -- the work of a developer is hard. It is even harder when there is a lack of good tools for testing and debugging software – particularly web services. In the past, I used to write test harnesses that required bulky IDE’s with steep learning curves. I was like, “surely, there has to be a better way to do this…” After some research, I found RESTClient. RESTClient is FireFox plugin for testing web services that is simple, low-level, and easy to use. I simply fill out the request and run it. Then RESTClient shows me exactly what the webserver sent without all the unnecessary fluff of a fancy IDE’s. Its simplicity has saved me hours of frustration and work. But don’t let the name fool you. RESTClient works with REST services, but it will also post back and receive XML and it works JSON data too. The bottom line is this: RESTCLient penultimate web service debugging tool because its simplicity and ease of use.
