Would someone provide an example on how this tool could be used to test a REST API? I think I'm missing something here. I'm not seeing how a fake response endpoint lets me test my REST API (shouldn't my test code invoke the API and validate that the real response was correct?)

One usecase I can think of is when UI developers are working on a set of expected response from an API while the API is currently being developed by backend developers. Once the API is ready, UI devs can swap the uri.

It seems to me that it isn't for testing a REST API but rather for testing something that depends on one without having to deal with real integration issues.

Yes, you explain better than me ;)

Your test code should invoke the real API if it's testing the real API. If you're testing a REST client, on the other hand, then it's best to unit test on a controlled set of requests and responses. Testing on the real API comes later, when you're doing integration.
