RoboHydra is a web server designed to help you test any kind of HTTP, HTTPS, or WebSockets client:
RoboHydra allows you to easily build custom “mock” servers with little effort, be it to build a test suite or to easily reproduce problems while fixing bugs. RoboHydra also supports exploratory testing by allowing you to change its behaviour dynamically via its web interface. Last but not least, RoboHydra can also reverse proxy requests, which is useful in a variety of situations.
To get started, go read the tutorial. There are also a number of screencasts in the YouTube channel, and Dev Opera published articles on how to use RoboHydra for front-end developer proxies and mock servers, and even one on advanced techniques.
For those of you already familiar with RoboHydra, there is also reference documentation available.
First, make sure you have Node.js installed (at least 0.6). Then, type the following in a terminal:
npm install robohydra

This project started at Opera Software ASA as an internal tool to test some of our projects. Large parts of this code were developed there, but as it’s pretty generic we decided to open source it.
