I need to make a junit test for this code that's called DeckTest It needs to test that there are 52 cards in a deck, 4 of each kind, and 13 of each suit. Then it needs to test that it actually makes a deck and test that it shuffles and test the public ArrayList getDeck() . The code below is the deck class and I just added the card class. Thank you

package code;

import java.util.ArrayList;

import java.util.Collections;

public class Deck {

private ArrayList deck;

public Deck() {

makeDeck();

shuffleDeck();

this.deck = getDeck();

}

public ArrayList getDeck() {

return this.deck;

}

public void makeDeck() {

ArrayList deck = new ArrayList<>();

for(int i = 1; i< 14; i++) {

Card card1 = new Card("HEARTS", i);

Card card2 = new Card("SPADES", i);

Card card3 = new Card("CLUBS", i);

Card card4 = new Card("DIAMONDS", i);

deck.add(card1);

deck.add(card2);

deck.add(card3);

deck.add(card4);

}

this.deck = deck;

}

public void shuffleDeck() {

Collections.shuffle(this.deck);

}

public static void main(String[] args) {

Deck deck = new Deck();

System.out.println(deck.getDeck());

}

}

package code;

public class Card {

private String suit;

private int rank;

public Card(String suit, int rank) {

this.rank = rank;

this.suit = suit;

}

public String getSuit() {

return suit;

}

public void setSuit(String suit) {

this.suit = suit;

}

public int getRank() {

return rank;

}

public void setRank(int rank) {

this.rank = rank;

}

@Override

public String toString() {

return "Card [suit=" + suit + ", rank=" + rank + "]";

}

}
