We want to preserve the operation that each test is verifying. This test should be an assertGreater, not an assertLessEqual. The same holds for any other tests that have had their operations changed to preserve the original test case. The value should change so the test accurately reflects what operation is being verified.

to clarify, instead of being assertFalse(a > b) it should beassertGreater(b, a), correct?

Hmm, in this case MinKey and MaxKey define their ge and such methods to be different. @ShaneHarvey can you offer the reasoning behind these tests?

We don't need duplicate assertions: the case above checks !=, and the case below checks ==.
