Need help making a TimeTest class that tests all of my public methods in Time.java using JUnit, I have provided Time.java below.

*** Here is my Time.java class BELOW ***

class Time implements Cloneable, Comparable { private int hour, minute; private boolean pm; public Time(int hour, int minute, boolean pM) { setHour(hour); setMinute(minute); this.pm = pM; } public int getHour() { return hour; } public void setHour(int hour) { if(hour < 1 || hour > 12) { throw new IllegalArgumentException(); } this.hour = hour; } public int getMinute() { return minute; } public void setMinute(int minute) { if(minute < 0 || minute > 59) { throw new IllegalArgumentException(); } this.minute = minute; } public boolean isPM() { return pm; } public void setPM(boolean pM) { this.pm = pM; } public static Time fromString(String string) { if(string.length() != 8) { throw new IllegalArgumentException("Invalid String"); } if(!string.contains(" ") || !string.contains(":")) { throw new IllegalArgumentException("Invalid String"); } String timePart = string.split(" ")[0]; String pm = string.split(" ")[1]; if(!pm.equals("AM") && !pm.equals("PM")) { throw new IllegalArgumentException("Invalid String"); } int h = Integer.parseInt(timePart.split(":")[0]); int m = Integer.parseInt(timePart.split(":")[1]); return new Time(h, m, pm.equals("PM")); } public void shift(int i) { minute += i; if(minute < 0) { while(minute < 0) { minute += 60; hour -= 1; if(hour == 0) { hour = 12; pm = !pm; } } } else if(minute > 59) { while(minute > 59) { minute = minute - 60; hour += 1; if(hour == 12) { pm = !pm; } else if(hour == 13) { hour = 1; } } } } @Override public int hashCode() { final int prime = 31; int result = 1; result = prime * result + hour; result = prime * result + minute; result = prime * result + (pm ? 1231 : 1237); return result; } @Override public boolean equals(Object obj) { if (this == obj) return true; if (obj == null) return false; if (getClass() != obj.getClass()) return false; Time other = (Time) obj; if (hour != other.hour) return false; if (minute != other.minute) return false; if (pm != other.pm) return false; return true; } public Time clone() { return new Time(hour, minute, pm); } @Override public int compareTo(Time o) { if(!o.isPM() && isPM()) { return 1; } else if(!isPM() && o.isPM()) { return -1; } int h1 = hour; if(h1 == 12) { h1 = 0; } int h2 = o.hour; if(h2 == 12) { h2 = 0; } if(h1 < h2) { return -1; } else if(h1 > h2) { return 1; } else { if(minute < o.minute) { return -1; } else if(minute > o.minute) { return 1; } else { return 0; } } } @Override public String toString() { return String.format("%02d:%02d ", hour, minute) + (isPM() ? "PM" : "AM"); } }
