Stub property setter with Rhino.Mocks to execute an action when called?

Question

This can be done with methods as follows:

myStub.Stub(x => x.SomeMethod()).WhenCalled(x => do something);

Is there any way the same thing can be done when a property setter is called?

Answer 1

The following will work:

Expect.Call(myStub.MyProperty).WhenCalled(p => Console.WriteLine("Called")).Return("Test result");

Please note that this only works if your properties (MyProperty in this case) is declared virtual.

Answer 2

I don't have Visual Studio handy, but I am sure something along these lines should work:

myStub.Stub(x => x.SomeProperty = null).WhenCalled(x => do something);

Answer 3

Put the mock back into "record" mode and use the old record/playback semantics to set the expectation for the property setter:

stub.BackToRecord();
Expect.Call(stub.SomeProperty).SetPropertyAndIgnoreArgument().WhenCalled(p => ...do something...);
stub.Replay();
