How do I do top-down tdd with typemock?

Hi Morten

Good question there are few possibilities here.
It depends on what do you have:

Do you know how the API of the underlying services will look like?
In that case you can write the skeleton code for it just to allow the tests
that call it pass compilation.
(NotImplementedException is your friend here :wink:)
Than in the tests use TypeMock to mock services methods.

If you don't know how the API is going to look like you can use TypeMock
for prototyping the underlying services. Write the interfaces or abstract class code and than use MockObject to create
instances that can be used in your tests.
You can than start slowly build from there the services.
I think this can give you a good 'feel' of how the API should look like from the customer point of view.

Please post here more details or code examples so we can help you
more specifically.
