According to your original spec the testing should be in a separate class called TestClock so:

Code:

public class TestClock {

    public static void main(String[] args) {
        ClockRx clock = new ClockRx();
        // now you can  call methods in the ClockRx class. for example

       // print details of clock
       System.out.println(clock);

       // tick the clock
       clock.tick();

       // print the current month name of clock
       System.out.println(clock.getMonthName());

       // call any other methods that you want to call

    }

}
