Provide a JUnit class with test cases for the attached Date class. You should have at least 12 test cases. Remember that a test should be small, and cover a single scenario.

Your tests should test both "good" and "bad" paths. For example, a some dates (like December 25) in your tests should be "good." Your tests should ensure that the correct season is returned for these dates. Some dates (like February 30) reflect an "unhappy path." Your tests should ensure that invalid dates are correctly flagged as "invalid."
