While writing tests tonight I ran into a surprise of some tests that
didn't go green after I added the implementation. Stepping through
the debugger yielded some unexpected (to me at least) return values
from the properties of a mock stub.
Here's a quick set of tests that illustrate the behavior. The test
fixture
"When_mocking_properties_with_RhinoMocks_stub_and_setting_expectations_afterward"
fails the tests
"Should_mock_value_int_property", "Should_mock_value_date_property",
and "Should_mock_nullable_value_date_property".
No patch given because
1) I'm not sure if the adding of the expectation afterward is
failing to remove all of the reference property expectations or
unintentionally removing existing value type property expectations
2) I'm insanely busy right now :)
