"Describe's full of it's with some beforeEach's."
That all a suite of unit tests is, really- just a describe statement, filled with some it statements, and usually one of two beforeEach statements. This is the Jasmine and chai/mocha syntax for writing unit tests. Once new developers realize this they can then proceed to write a trivial test with all the parts (something like expect 1 + 1 to be 2) and fire up their test runner. Now they've crossed into the land of unit testing. They went from not even knowing where to start to now asking about how to inject services, make mocks, and run only subsections of tests. It's amazing seeing the speed at which programmers progress in their unit testing understanding once they can grasp this one simple phrase: Describes full of it's with some beforeEach's.
