Infrastructure interfaces are owned by domain, used only for initialize function. This is because the unit test should be written manually, and the programmer who’s writing it understands that a unit test is important as the main code. Paraphrased from the book's figure 2.13, the erroneous implementation creates this dependency graph: The arrows show the direction of dependencies; i.e. I had a hard time coming up with this post’s title because the pattern comes in many flavors. There is also a reason for “make it first” thing that makes the code unorganized. This small project represents user registration example. Naming, on the other hand, depends on each programmer, because it is seriously the hardest part of coding. Before you start to generate the mocks for any domain.
