clarify how to test routes properly

[avdd]

Could we get a description about how to properly test routes?

I'm getting hit by the issue in #2717 (default routes and unexpected GET requests) but the discussion there is mostly unhelpful.

If it's intended that $route fetch the default route every time it's injected (which seems bizarre), how do I write clean tests? Is the Right Way to pollute the tests with $templateCache or $httpBackend.expect noise? or is there a better way?

Is this really unhelpful? #2717 (comment)

They way I have done it, is to separate the modules. A main module that contains the app / route config, and a module for controllers, directives etc. If I'm testing a route controller I only require the controller module and mock out the app config as needed.
