Hi. Very nice post. I have a doubt. In the test for partial user_details.rb all test cases for the functionality inside it are present. Now when writing test for user.rb what should be tested ?

1. Everything inside user_details.rb and user.rb OR
2. Test everything insideuser_details.rb and stub/mock user.rb

I thing option 2 makes sense but I would like to know your opinion for clarity.

Thanks.
