c# - RhinoMocks 在泛型方法中抛出 InvalidOperationException

Question

我有一个类，我想在我的测试中模拟它，这是它接口(interface)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。当我在里面打断点，查看这个methodInfo是什么的时候，发现其实不是IsRegistered<>方法，但是 GetAllInstrumentsAffectedByFixSide .

为什么 Rhino 尝试调用 GetGenericMethodDefinition方法GetAllInstrumentsAffectedByFixSide在 IsRegistered<> 的模拟通话中？ GetGenericMethodDefinition之前发生过电话。看起来它只是混淆了这两种方法。

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);

当我将其更改为不使用 .Expect 并使用 LastCall 的直接设置时 - 它确实有效。有什么想法吗？我更改了上面的代码以反射(reflect)问题。

此问题已在版本 3.6.1 中得到纠正

我认为从版本 3.6.0 更新应该不是问题，因为所有构造都保留
