There is a good guide here

You need to play around with structure map and mocking framework some :)

Hi Daniel,

Thanks for reply. I can add all services and mock special features that I need.

I just wonder if I can load the other services that I don't need to mock by injection.

Using FakeMaker, I can create almost all of my EpiServer's structure and I just need to mock methods that use EpiServer or its data, after that I can test everything, including big services

Best way I know is to dotPeek Episerver.Global and look for IInitializableModule and copy those configurations and use them to set up "real" Episerver mappings. Version 2 is to avoid using dependencies to those in code and have a separate abstraction layer above them which are easier to mock. If you are using real calls to Episerver it will be more of an integration test of course.

Thanks Daniel
