我可以在Rhino-Mocks 3.6中使用AAA语法测试方法调用顺序吗？

Question

如果Method1在Rhino-mocks 3.6中调用1st,然后调用After后面的Method2,然后使用AAA语法调用Method3,是否可以测试以下示例？

// Assert
var mock = MockRepository.GenerateMock<ISomeService>();

// Act
myObject.Service = mock;

// How should I change this part to ensure that Rhino Mocks check the call order as well?
mock.AssertWasCalled(m=>m.Method1());
mock.AssertWasCalled(m=>m.Method2());
mock.AssertWasCalled(m=>m.Method3());

Answer 1

这是一种方法......

mock.AssertWasCalled(m=>m.Method1(), options => options.WhenCalled(w => mockService.AssertWasNotCalled(x=>x.Method2())));
mock.AssertWasCalled(m=>m.Method2(), options => options.WhenCalled(w => mockService.AssertWasNotCalled(x=>x.Method3())));
mock.AssertWasCalled(m=>m.Method3());

Answer 2

你可以,但你真的不应该.您应该专注于测试externall可观察行为,而不是实现.

方法调用顺序可以在不影响与API客户端的合同的情况下进行更改.在这种情况下,您的测试将失败,即使它不应该.

简而言之,测试实施会导致脆弱的测试.脆弱的测试导致放弃测试.你不想去那里.

希望这可以帮助.

以下是如何做得很好.

var mocks = new MockRepository();
var fooMock = mocks.DynamicMock<IFoo>();
using (mocks.Ordered())
{
    fooMock.Expect(x => x.Method1());
    fooMock.Expect(x => x.Method2());
}
fooMock.Replay();

var bar = new Bar(fooMock);
bar.DoWork();

fooMock.VerifyAllExpectations();
