There many tools for testing REST APIs by mimicking a client, but I need the other side- test my client. I wrote a simple server using Flask, but I was hoping for something that includes builtin logging, scripting and configuration out of the box with no need for coding.
Interfake is another option. You can create HTTP servers from a JSON file or through a straightforward JS API.
Have a look at Frisbyjs. It is built on top of node.js and Jasmin suitable for end2ent testing.
I would say easy to config and use.
