计数方法调用Rhino Mocks

Question

所以:我想在Rhino Mocks中使用比Any(),Once()或AtLeastOnce()更具体的方法来计算方法调用.这样做有什么机制吗？

Answer 1

诀窍是使用Repeat.Times(n),其中n是次数.

令人惊讶的是,即使该方法比预期更频繁地被调用,下面的测试也会通过:

[Test]
public void expect_repeat_n_times_does_not_work_when_actual_greater_than_expected() {
  const Int32 ActualTimesToCall = 6;
  const Int32 ExpectedTimesToCall = 4;

  var mock = MockRepository.GenerateMock<IExample>();
  mock.Expect(example => example.ExampleMethod()).Repeat.Times(ExpectedTimesToCall);

  for (var i = 0; i < ActualTimesToCall; i++) {
      mock.ExampleMethod();
  }

  // [?] This one passes
  mock.VerifyAllExpectations();
}

要解决此问题,请使用以下方法:

[Test]
public void aaa_repeat_n_times_does_work_when_actual_greater_than_expected() {
  const Int32 ActualTimesToCall = 6;
  const Int32 ExpectedTimesToCall = 4;

  var mock = MockRepository.GenerateMock<IExample>();

  for (var i = 0; i < ActualTimesToCall; i++) {
      mock.ExampleMethod();
  }

  // This one fails (as expected)
  mock.AssertWasCalled(
      example => example.ExampleMethod(),
      options => options.Repeat.Times(ExpectedTimesToCall)
  );
}
