Poker Game: Unit testing different poker hands without violating DRY principles
$begingroup$
I'm currently in the process of refactoring an old poker game which violates many of the SOLID principles.
I was trying to use the TDD approach to refactoring and I found myself having to hard code a player's hand every time I wrote a unit test for a specific poker hand check.
For example, here are the unit tests for a one pair poker hand check:
[Test]
public void OnePair_IsLowPair_ReturnsTrue()
{
SuperCard testHand =
{
new CardClub(Rank.Ace),
new CardSpade(Rank.Ace),
new CardDiamond(Rank.Five),
new CardHeart(Rank.Jack),
new CardClub(Rank.Three)
};
bool result = PokerHandEvaluator.OnePair(testHand);
Assert.That(result == true);
}
[Test]
public void OnePair_IsLowerMiddlePair_ReturnsTrue()
{
SuperCard testHand =
{
new CardClub(Rank.Eight),
new CardSpade(Rank.Ace),
new CardDiamond(Rank.Ace),
new CardHeart(Rank.Jack),
new CardClub(Rank.Three)
};
bool result = PokerHandEvaluator.OnePair(testHand);
Assert.That(result == true);
}
[Test]
public void OnePair_IsHigherMiddlePair_ReturnsTrue()
{
SuperCard testHand =
{
new CardClub(Rank.Jack),
new CardSpade(Rank.Queen),
new CardDiamond(Rank.Ace),
new CardHeart(Rank.Ace),
new CardClub(Rank.Three)
};
bool result = PokerHandEvaluator.OnePair(testHand);
Assert.That(result == true);
}
[Test]
public void OnePair_IsHighPair_ReturnsTrue()
{
SuperCard testHand =
{
new CardClub(Rank.Jack),
new CardSpade(Rank.Deuce),
new CardDiamond(Rank.Six),
new CardHeart(Rank.Ace),
new CardClub(Rank.Ace)
};
bool result = PokerHandEvaluator.OnePair(testHand);
Assert.That(result == true);
}
This is what the class diagram (at the project's current stage) looks like:
My question is how I should go about extracting a method (or methods) out of the testHand initialization.

Maybe make a "CreateHand()" function that takes a string like "AcAs5dJh3c"?

A CreateHand() is essentially what I'm trying to go for here but I'm not sure how to implement your idea. Can you please share some pseudocode or code?

You also need to post the code you are testing. The tests are worthless without it.

By the code that I'm testing, do you mean the code for the OnePair() method? If not, could you please clarify?
