Create CardTest.cs file in Poker.Test
[Fact]
public void CanDescribeCard()
{
var card = new Card(CardValue.Ace, CardSuit.Spades);
Assert.Equal("Ace of Spades", card.ToString());
}
Add project reference to Poker.Test Command:
dotnet add reference ../Poker.Library/Poker.Library.csproj
Add the next files to Poker.Library CardSuit.cs
public enum CardSuit
{
Spades,
Diamonds,
Clubs,
Hearts
}
CardValue.cs
public enum CardValue
{
Two = 2,
Three,
Four,
Five,
Six,
Seven,
Eight,
Nine,
Ten,
Jack,
Queen,
King,
Ace
}
Card.cs
public class Card
{
public Card(CardValue value, CardSuit suit)
{
Value = value;
Suit = suit;
}
public CardValue Value { get; set;}
public CardSuit Suit { get; set;}
}
When this test passes, move on to the next exercise.
Add HandTest.cs file to Poker.Test project
[Fact]
public void CanCreateHand()
{
var hand = new Hand();
Assert.True(hand.Cards.Count() == 0);
}
[Fact]
public void CanHandDrawCard()
{
var card = new Card(CardValue.Ace, CardSuit.Spades);
var hand = new Hand();
hand.Draw(card);
Assert.Equal(hand.Cards.First(), card);
}
Add Hand.cs file to Poker.Library
public class Hand
{
public Hand()
{
Cards = new List<Card>();
}
public List<Card> Cards { get;}
public void Draw(Card card)
{
Cards.Add(card);
}
}
When this test passes, move on to the next exercise.
Add the next test:
[Fact]
public void CanGetHighCard()
{
var hand = new Hand();
hand.Draw(new Card(CardValue.Seven, CardSuit.Spades));
hand.Draw(new Card(CardValue.Ten, CardSuit.Clubs));
hand.Draw(new Card(CardValue.Five, CardSuit.Hearts));
hand.Draw(new Card(CardValue.King, CardSuit.Hearts));
hand.Draw(new Card(CardValue.Two, CardSuit.Hearts));
Assert.Equal(CardValue.King, hand.HighCard().Value);
}
When this test passes, move on to the next exercise. (Tip: if the collection is sort is easy)
Add the HandRank enum to your project
public enum HandRank
{
HighCard,
Pair,
TwoPair,
ThreeOfAKind,
Straight,
Flush,
FullHouse,
FourOfAKind,
StraightFlush,
RoyalFlush
}
And add the next test to your HandTest file.
[Fact]
public void CanScoreHighCard()
{
var hand = new Hand();
hand.Draw(new Card(CardValue.Seven, CardSuit.Spades));
hand.Draw(new Card(CardValue.Ten, CardSuit.Clubs));
hand.Draw(new Card(CardValue.Five, CardSuit.Hearts));
hand.Draw(new Card(CardValue.King, CardSuit.Hearts));
hand.Draw(new Card(CardValue.Two, CardSuit.Hearts));
Assert.Equal(HandRank.HighCard, hand.GetHandRank());
}
[Fact]
public void CanScoreFlush()
{
var hand = new Hand();
hand.Draw(new Card(CardValue.Two, CardSuit.Spades));
hand.Draw(new Card(CardValue.Three, CardSuit.Spades));
hand.Draw(new Card(CardValue.Ace, CardSuit.Spades));
hand.Draw(new Card(CardValue.Five, CardSuit.Spades));
hand.Draw(new Card(CardValue.Six, CardSuit.Spades));
Assert.Equal(HandRank.Flush, hand.GetHandRank());
}
[Fact]
public void CanScoreRoyalFlush()
{
var hand = new Hand();
hand.Draw(new Card(CardValue.Ten, CardSuit.Spades));
hand.Draw(new Card(CardValue.Jack, CardSuit.Spades));
hand.Draw(new Card(CardValue.Queen, CardSuit.Spades));
hand.Draw(new Card(CardValue.King, CardSuit.Spades));
hand.Draw(new Card(CardValue.Ace, CardSuit.Spades));
Assert.Equal(HandRank.RoyalFlush, hand.GetHandRank());
}
When this test passes, move on to the next exercise.
Card class Hand class
Add the next test to HandTest.cs.
[Fact]

hand.Draw(new Card(CardValue.Ten, CardSuit.Hearts));
hand.Draw(new Card(CardValue.Ace, CardSuit.Spades));
Assert.Equal(HandRank.Pair, hand.GetHandRank());
}
[Fact]
public void CanScoreThreeOfAKind()

hand.Draw(new Card(CardValue.Jack, CardSuit.Spades));
hand.Draw(new Card(CardValue.Nine, CardSuit.Spades));
hand.Draw(new Card(CardValue.Ten, CardSuit.Hearts));
hand.Draw(new Card(CardValue.Ten, CardSuit.Spades));
Assert.Equal(HandRank.ThreeOfAKind, hand.GetHandRank());
}
[Fact]
public void CanScoreFourOfAKind()

hand.Draw(new Card(CardValue.Ten, CardSuit.Clubs));
hand.Draw(new Card(CardValue.Jack, CardSuit.Spades));
hand.Draw(new Card(CardValue.Ten, CardSuit.Spades));
hand.Draw(new Card(CardValue.Ten, CardSuit.Hearts));
hand.Draw(new Card(CardValue.Ten, CardSuit.Spades));
Assert.Equal(HandRank.FourOfAKind, hand.GetHandRank());
}
[Fact]
public void CanScoreFullHouse()
{
var hand = new Hand();
hand.Draw(new Card(CardValue.Ten, CardSuit.Clubs));
hand.Draw(new Card(CardValue.Jack, CardSuit.Spades));
hand.Draw(new Card(CardValue.Ten, CardSuit.Spades));
hand.Draw(new Card(CardValue.Jack, CardSuit.Hearts));
hand.Draw(new Card(CardValue.Ten, CardSuit.Spades));
Assert.Equal(HandRank.FullHouse, hand.GetHandRank());
}
When this tests pass, move on to the next exercise.
Add the next test to HandTest class
[Fact]
public void CanScoreStraight()
{
var hand = new Hand();
hand.Draw(new Card(CardValue.Ten, CardSuit.Clubs));
hand.Draw(new Card(CardValue.Jack, CardSuit.Spades));
hand.Draw(new Card(CardValue.Queen, CardSuit.Spades));
hand.Draw(new Card(CardValue.King, CardSuit.Hearts));
hand.Draw(new Card(CardValue.Ace, CardSuit.Spades));
Assert.Equal(HandRank.Straight, hand.GetHandRank());
