我正在尝试学习 Rhino Mocks AAA 语法，但在断言某个方法（带有任何参数值）被调用时遇到了麻烦。我使用 Machine.Specifications 作为我的测试框架。
这个特定的方法是通用的，我想确保它被三种不同的类型调用了三次。
repo.Save<T1>(anything), repo.Save<T2>(anything), and repo.Save<T3>(anything)
我为每种类型的函数存根。但我得到了一个有趣的结果。（以下）
[Subject("Test")]
public class When_something_happens_with_constraint
{
static IRepository repo;
static TestController controller;
static ActionResult result;
Establish context = () =>
{
repo = MockRepository.GenerateMock<IRepository>();
controller = new TestController(repo);
repo.Stub(o => o.Save<Something>(Arg<Something>.Is.Anything));
repo.Stub(o => o.Save<SomethingElse>(Arg<SomethingElse>.Is.Anything));
repo.Stub(o => o.Save<AnotherOne>(Arg<AnotherOne>.Is.Anything));
};
//post data to a controller
Because of = () => { result = controller.SaveAction(new SomethingModel() { Name = "test", Description = "test" }); };
//controller constructs its own something using the data posted, then saves it. I want to make sure three calls were made.
It Should_save_something = () => repo.AssertWasCalled(o => o.Save<Somethign>(Arg<Something>.Is.Anything));
It Should_save_something_else = () => repo.AssertWasCalled(o => o.Save<SomethingElse>(Arg<SomethingElse>.Is.Anything));
It Should_save_another_one = () => repo.AssertWasCalled(o => o.Save<AnotherOne>(Arg<AnotherOne>.Is.Anything));
}
结果是两个例外和一个通过。
第一个调用抛出：
System.InvalidOperationException：没有设置要验证的期望，确保操作中的方法调用是虚拟（C#）/可覆盖（VB.Net）方法调用
第二个抛出：
System.InvalidOperationException：录制时仅在模拟方法调用中使用 Arg。预期 1 个参数，已定义 2 个。
第三个通过了……出于某种奇怪的原因。
我还尝试在我的设置中将 GenerateMock() 与 Expect 结合使用，以及将 GenerateStub() 与 Stub 结合使用。两者都得到了完全相同的结果。我一定是做错了什么。
我正在使用：MachineSpec 0.3.0.0 和 RhinoMocks 3.6.0.0
有任何想法吗？

这是在 Lee 的帮助下的完整（工作版本）。我正在使用一个额外的（非 linq）层。我的实际问题是我的一项测试在离线真实代码中重新使用了错误的 lambda 变量。它应该做某事 = () => repo.AssertWasCalled( o => repo .Save(data)); //错误的lambda
所以这里有一个正确测试的样本供参考。
