我想断言一个方法只被调用一次。我使用RhinoMocks 3.5。
这里是我认为会工作：
[Test]
public void just_once()
{
var key = "id_of_something";
var source = MockRepository.GenerateStub<ISomeDataSource>();
source.Expect(x => x.GetSomethingThatTakesALotOfResources(key))
.Return(new Something())
.Repeat.Once();
var client = new Client(soure);
// the first call I expect the client to use the source
client.GetMeMyThing(key);
// the second call the result should be cached
// and source is not used
client.GetMeMyThing(key);
}
如果第二次调用GetMeMyThing()调用source.GetSomethingThatTakesALotOfResources()，我想这个测试失败。
下面是我如何验证一个方法被调用一次。

public void just_once()
{
// Arrange
var a = MockRepository.GenerateMock<ISomeDataSource>();
a.Expect(x => x.GetSomethingThatTakesALotOfResources()).Return(new Something()).Repeat.Once();
a.Stub(x => x.GetSomethingThatTakesALotOfResources()).Throw(new InvalidOperationException("gotcha"));
// Act
// First invocation should call GetSomethingThatTakesALotOfResources
a.GetMeMyThing();
// Second invocation should return cached result
a.GetMeMyThing();
// Assert
a.VerifyAllExpectations();
}
