我有一个类，我想在我的测试中模拟，这是它界面的一部分：

interface IInventory
{
    Instrument[] GetAllInstrumentsAffectedByFixSide(int fixSideNumber);

    bool IsRegistered<T>(string name, int? fixSideNumber) where T : InventoryObject;
}

我的记录是这样的：

using (mockRepository.Record())
{
    inventory.GetAllInstrumentsAffectedByFixSide(0);
    LastCall.Return(new Instrument[0]);

    inventory.Expect(x => x.IsRegistered<TestInstrument>("ActivatorInstrument", null)).IgnoreArguments().Return(true)
}

但是当我在我的测试代码中写这个时：

TestHandler.Inventory.IsRegistered<TestInstrument>("ActivatorInstrument", null)

它抛出 InvalidOperationException。它抛出这个异常的地方很有趣——它是MethodInfo.GetGenericMethodDefinition()

它的来源看起来像：

public override MethodInfo GetGenericMethodDefinition()
{
    if (!IsGenericMethod)
        throw new InvalidOperationException();
    Contract.EndContractBlock();

    return RuntimeType.GetMethodBase(m_declaringType, RuntimeMethodHandle.StripMethodInstantiation(this)) as MethodInfo;
}

所以这个方法实际上是在非泛型方法上调用的。当我在里面放了一个断点，查看这个methodInfo是什么，发现其实不是IsRegistered<>method，而是GetAllInstrumentsAffectedByFixSide.

为什么 Rhino 试图在 mock-call for中调用GetGenericMethodDefinitionfor 方法？电话发生在以前。看起来它只是混淆了这两种方法。GetAllInstrumentsAffectedByFixSideIsRegistered<>GetGenericMethodDefinition

Upd我在问题中犯了一个错误：我实际上将期望设置为：

inventory.Expect(x => x.IsRegistered<TestInstrument>("ActivatorInstrument", null)).IgnoreArguments().Return(true);

当我将其更改为没有 .Expect 和 LastCall 的直接设置时，它实际上可以工作。有什么想法吗？我已经更改了上面的代码，以反映问题。

此问题已在 3.6.1 版中得到纠正

我不认为从版本 3.6.0 更新应该是一个问题，因为所有的结构仍然存在
