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