パーサーを書く必要があります。テストしたい入力形式はたくさんありますが、出力はかなり複雑です。同様のテストで異なる入力と出力をテストするにはどうすればよいですか?

例えば

public class Person
{
    public string Name;
    public int Age;
    public string Comment;
}

public interface IParser
{
    Person Parse(string input);
}

public class Parser : IParser
{
    public Person Parse( string input )
    {
        var fields = input.Split(',');

        var p = new Person
        {
            Name = fields[0],
            Age = int.Parse(fields[1])
        };

        p.Comment = fields.Length == 3 ? fields[2] : ""; 

        return p;
    }
}

私はこれらのテストを書きました...

public class ParserTests
{
    protected string _input;
    protected Person _expected;

    private IParser _parser = new Parser();
    private Person _actual { get { return _parser.Parse(_input); } }

    [TestMethod]
    public void Parse_Name()
    {
        Assert.AreEqual(_expected.Name, _actual.Name);
    }

    [TestMethod]
    public void Parse_Age()
    {
        Assert.AreEqual(_expected.Age, _actual.Age);
    }

    [TestMethod]
    public void Parse_Comment()
    {
        Assert.AreEqual(_expected.Comment, _actual.Comment);
    }
}

[TestClass]
public class ParserTestsWithoutComment : ParserTests
{
    public ParserTestsWithoutComment()
    {
        _input = "John,29";
        _expected = new Person { Name = "John", Age = 29, Comment = "" };
    }
}

[TestClass]
public class ParserTestsWithComment : ParserTests
{
    public ParserTestsWithComment()
    {
        _input = "Brian,99,test";
        _expected = new Person { Name = "Brian", Age = 99, Comment = "test" };
    }
}

私は単体テストが初めてで、より複雑なものから始める方法がわかりません。私の実際の入力ファイルはもっと複雑です

Handそして、私が取り組んでいるクラスに解析したい...

public class Hand
{   
    public long ID; 
    public string Stakes; 
    public DateTime Date; 

    public IDictionary<Street, decimal> Pots;
    public decimal FinalPot; 
    public decimal Rake; 

    public Player Hero; 
    public IDictionary<Player, PlayerInfo> Players; 

    public IList<Card> Board; 

    public IList<Decision> Actions; 

    public Hand()
    { 
        this.Players = new Dictionary<Player, PlayerInfo>();
        this.Board = new List<Card>();
        this.Actions = new List<Decision>();
        this.Pots = new Dictionary<Street, decimal>();
    }
}

public class PlayerInfo
{
    public Player Player;
    public decimal Stack;
    public decimal Summary;
    public Position Position;
    public Card Holecards;
}

あなたのソリューションは機能していますが、グローバル変数と継承を組み合わせているため、理解が困難です。

NUnit 2.5 以降を使用している場合は、 TestCaseAttribute でパラメーター化されたテストを使用できます。

[TestCase("John,29","John",29,"")]
[TestCase(",13","",13,"")]
public void ParserTest(Sting stringToParse, String expextedName, int expectedAge, String expectedComment)
{
    IParser _parser = new Parser();
    Person _actual = _parser.Parse(stringToParse);

    Assert.AreEqual(expextedName, _actual.Name, stringToParse + " failed on Name");
    Assert.AreEqual(expextedAge, _actual.Age, stringToParse + " failed on Age");
    Assert.AreEqual(expextedComment, _actual.Comment, stringToParse + " failed on Comment");
}

これは非常に理解しやすいと思います。

mstest を使用する必要がある場合は、how-to-rowtest-with-mstestで説明されているようにシミュレートする必要があります。
