You make a good point. And in truth, my primary interest is not in
verifying what's injected. I'm exploring the creation of a jasmine
extension that will greatly assist in the creation of mocks for all
dependencies injected into controllers, services, filters, etc.
The concept is this:
* mock all dependencies,
* in your "given" statements, specify how these mocks will respond when
called,
* only in your "then" statements do you passThrough to the actual code.
This gives the code under test total isolation, and forces your tests to be
explicit about the conditions for the test. If you follow the AngularJS
mandate that dependencies be injected, and you have access to those
dependencies in the setup for the test, then you should be able to mock all
dependencies with a single line of code. Something like:
dep = spyOnControllerDependencies(MyController);
Where "dep" is an object containing the mocked/spied on dependencies.
Perhaps I should have been more forthcoming at the get go, but I was
worried about verging into tl;dr territory.
