ember-cli sinon.js xhr tests examples?

So, I want to test the XHR requests on an ember-cli app, After endless googling/searching, I couldn't find a good resource/test suites that explains/shows how to use sinon's fakeServer or useFakeXMLHttpRequest, most of the examples shows you some very basic tests with fake data.

Are there any real examples/projects I could look at to learn from?

Thanks in advance
