TDD Lab Practice

• Your task in this practice is to write test cases for a Clock class. The code exists in the public repository.
• A Clock object represents the daily time.
• Take a look at the methods declared in the given Clock class. For each method, write test cases in the given (and currently empty) ClockTest class in the test package.
• Carefully design your test cases to cover corner cases.
• Clock’s constructor should throw IllegalArgumentException if the hour, minutes, or the seconds parameters are not proper values. (E.g. 79 is illegal for seconds, 30 is illegal for the hour.)
