NOTE: Just released version 0.3 of ngImprovedTesting with lots of bug fixes.
Check out this blog post or the README of the GitHub repo for more info.

However the learning curve for writing (proper) unit tests tends to be quite steep. This is mainly because AngularJS doesn't really offer any high level API's to ease the unit testing. Instead you are forced to use the same (low level) services that AngularJS uses internally. That means you have to gain in dept knowledge about the internals of $controller, when to $digest and how to use $provide in order to mock these services. Especially mocking out a dependency of controller, filter or another service is too cumbersome. This blog will show how you would normally create mocks in AngularJS, why its troublesome and finally introduces the new ngImprovedTesting library that makes mock testing much easier.
