Rhino Mocks 中的计数方法调用 [英] Counting method calls in Rhino Mocks

问题描述

所以:我想用比 Any()、Once() 或 AtLeastOnce() 更具体的东西来计算 Rhino Mocks 中的方法调用.有什么机制可以做到这一点吗?

So: I'd like to count method calls in Rhino Mocks with something more specific than Any(), Once() or AtLeastOnce(). Is there any mechanism for doing this?

推荐答案

诀窍是使用 Repeat.Times(n)，其中 n 是次数.

The trick is to use Repeat.Times(n), where n is the number of times.

令人惊讶的是，即使调用该方法的频率比预期的要高，以下测试也会通过:

Suprisingly the below test will pass, even if the method is called more often than expected:

[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:

To work around this use the below method:

[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)
  );
}
