We have an HTTP Rest API that uses some JSON/XML http requests, that are easily created and send through Fiddler or Rest Console (Chrome plugin). Then we verify the response and use it to form our next request. This process is simple and effective in our manual testing. For automation testing though we need a tool that can do those requests and also response verifications and variable usage for those HTTP requests (POST, GET, DELETE, etc.). Of course, that needs to come with a lot more functionalities (data driven testing, random generation of variables, loops, etc.) It will be great if this feature can be used side-to-side with the Web UI testing capabilities of Test Studio.
