Thank you Rao.
I figured out a solution to my problem. I'm not sure if it's the right way to do it, but it seems to work just fine.
Anyone out there with a similar question, here is a summary of what I did:
I had a WADL for a REST service that has not yet been implemented. It will be my responsibility to test it once it is implemented. So I wanted to start getting familiar with the interface before the service was actually ready. I thought the MOCK REST service feature might be just what I was looking for.
I created a REST service from the WADL I had. Then I noticed the "Generate MOCK REST service" menu item. I used it to generate a MOCK REST service from the REST service I created from the WADL.
But then I was having trouble executing the MOCK REST service using the REST service from the WADL as the underlying service. After playing with it for two days I tried something. First I changed the URL in the WADL for the resource in the service to my local machine name. Then I recreated the service from the changed WADL. After I used "Generate MOCK REST service" to recreate the MOCK service I changed the port number generated to match the port I used in the WADL. Then I created a test suite and test case in the project that contains both the service and the MOCK service. I added a response to the MOCK services and then added an assertion to the request test step in my test case. I made the assertion validate the response I wrote for the MOCK service, started up the MOCK service and ran the test case. It worked perfectly!
The last thing I did was figure out how to run different test cases using the same request from the REST service I created with the WADL and using different actions I created with different resources for the MOCK service and different test cases I created in the original test suite. Each time I ran a test case I would simply change the resource for the REST service request to match the resource for the specific MOCK REST service response I wanted to test.
I hope this helps anyone else that wants to do something similar.
