下面，我有一个我想测试的对象的代码。我在测试中使用了部分模拟，并希望在测试 GenerateReport 方法时模拟对 InsertData 的调用。出于某种原因，我的测试继续通过 InsertData 到 DoSomeStuff 并在 Path.Combine 行上失败。我错过了什么？

public class MyClass : IMyClass
{
    private readonly IMyClassDataProvider _myClassDataProvider;

    public virtual string WorkingDirectory { get; set; }

    public MyClass(IMyClassDataProvider myClassDataProvider)
    {
        _myClassDataProvider = myClassDataProvider;
    }

    internal virtual void ValidateWorkingDirectory()
    {
        if (string.IsNullOrEmpty(WorkingDirectory))
        {
            throw new ApplicationException("Must set Working Directory before any method calls.");
        }
    }

    public virtual void GenerateReport(vars)
    {
        ValidateWorkingDirectory();
        InsertData(_myClassDataProvider.GetData(vars), "ReportName"); 
                    //want to mock the call above
    }

    internal virtual void InsertData(DataSet analysis, string fileName)
    {
        DoSomeStuff();
    }

    private static void DoSomeStuff()
    {
        string fileName = FileNameProvider.Get();
        Path.Combine(WorkingDirectory, fileName); //fails here!
    }
}


[TestFixture]
public class MyClassTests : TestFixtureBase
{
    private MockRepository _mocks;
    private IMyClassDataProvider  _myClassDataProvider;
    private MyClass _myClass;
    private var _vars;

    [SetUp]
    protected void Init()
    {
        _mocks = new MockRepository();
        _myClassDataProvider = _mocks.StrictMock<IMyClassDataProvider >();
        _myClass = _mocks.PartialMock<MyClass>(_myClassDataProvider);
        _vars = "who cares";
    }

    [Test]
    public virtual void ShouldGenerateReport()
    {
        DataSet dataSetToReturn = new DataSet();
        using (_mocks.Ordered())
        {
            Expect.Call(() => _myClass.ValidateWorkingDirectory());
            Expect.Call(_myClassDataProvider.GetData(vars)).Return(dataSetToReturn);
            Expect.Call(() => _myClass.InsertData(dataSetToReturn, "ReportName"));
        }
        _mocks.ReplayAll();
        _myClass.GenerateReport(vars);
        _mocks.VerifyAll();
    }
}

将 InsertData 从 internal 更改为 public 将解决此问题。我假设 Rhino 模拟需要公开一个方法才能模拟方法调用。

关于在期望之后添加 IgnoreArguements，我不太确定这是如何通过的，因为当我尝试运行此代码时它仍然调用原始方法。

希望这可以帮助
