24// Notes about this unit test
25// --------------------------
26// KSAction is an abstract class, and there's currently nothing to isolate and
27// test in this unit test. So, here we'll just test that we can instantiate it
28// (yes, I know we're instantiating an "abstract" class, but at least it ensures
29// that everything compiles and all the machinery works up to that point) and
30// verify that we get a non-nil instance. If more functionality is added to the
31// KSAction class in the future, the unit test is already setup for it.
32//
33// Also note that we *can* test how concrete KSAction instances interact with
34// the KSActionProcessor, and we do that in the KSActionProcessorTest file.
