Hi, everyone.
I'm pretty new to mocking and TDD. I work in VS2008 with MSTest and
Rhino.Mocks 3.6.
Below is the class I'm working on and its test harness below it. I'm
trying to mock the method [FindDataSetInDatabaseRegister]. But I keep
getting the same exception with each approach I try.
As you can see, I'm using the private accessor that MSTest creates. I
don't know if this is the main reason that my test keeps failing on
the setting up of the specific method call.
In approach 1 and 2: if I don't have the mock.ReplayAll(); then the
IDataProvider mock is not used and the method setup fails. If the
[mock.ReplayAll();] is there, then, when the method is recorded, the
mock IDataProvider IS used and the method is partially recorded. Then
the exceptions (noted at the end) are thrown.
In approach 4 ("TRY 4") the recording doesn't cause an error and the
actual test code is executed. But then the mocked method is not
substituted and the real method is called instead.
Could anyone please assist me with this problem?
Thanks
Chris

Doesn't throw the previous errors. But the mock isn't used at all.
The call gets through
to the DAL method instead of the mocked FindDataSetInDatabaseRegister-
method (which is invoked much earlier).
