What is ReplayAll() and VerifyAll() in RhinoMocks

问题

[Test]
public void MockAGenericInterface()
{
    MockRepository mocks = new MockRepository();
    IList<int> list = mocks.Create Mock<IList<int>>();
    Assert.IsNotNull(list);
    Expect.Call(list.Count).Return(5);
    mocks.ReplayAll();
    Assert.AreEqual(5, list.Count); 
    mocks.VerifyAll();
}

What is the purpose of ReplayAll() and VerifyAll() in this code?

回答1:

The code snippet demonstrates the Record/Replay/Verify syntax of Rhino.Mocks. You first record the expectations for a mock (using Expect.Call(), then you call ReplayAll() to run the mock simulation. Then, you call VerifyAll() to verify that all the expectations have been met.

This is an obsolete syntax, by the way. The new syntax is called AAA Syntax - Arrange, Act, Assert and is usually easier to work with than the old R/R/V one. You code snipped translated to AAA:

  [Test]
  public void MockAGenericInterface()
  {
    IList<int> list = MockRepository.GenerateMock<IList<int>>();
    Assert.IsNotNull(list);
    list.Expect (x => x.Count).Return(5);
    Assert.AreEqual(5, list.Count); 
    list.VerifyAllExpectations();
  }
