Question

I have two packages in my project: odp.proj and odp.proj.test. There are certain methods that I want to be visible only to the classes in these two

Answer 1

When I do this in IntelliJ, my source tree looks like this:

src         // source root

- test      // test root
  - odp
     - proj // JUnit or TestNG source here
