Didier Loiseau commented on MNG-1378:
-------------------------------------
Then I guess dependencies on test-jars should be completely disallowed. If your
tests depend on some test-jar, and you don't have the dependencies of that
test-jar, it is well possible that your tests cannot compile at all!
It is not just a question of extending test cases, it could also be a question
of reusing some other classes of the test-jar.
For example, suppose you have module X and module Y which depends on X. In the
test classes of module X, you implement a {{TestUtil}} class which relies on
some other class of X's main classpath and on some class from a test-scoped
dependency. Of course, the tests of X depend on {{TestUtil}}.
Now, in the tests of module Y, you would like to reuse {{TestUtil}}. You thus
need to declare a test-scoped dependency on X's test-jar. But for the moment
you also have to redeclare all the test-scoped dependencies of X in order to
use that class. And you cannot move that class somewhere else, due to its
dependencies.

> test-jar transitive dependencies are calculated as per compile scope rather
> than test scope.
> The situation is demonstrated nicely in it0077:
> * module sub1 has a test-scoped dependency of commons-lang
> * module sub2 has a test-scoped dependency of sub1 test-jar
> sub2 tests should inherit the commons-lang transitive dependency. For
> example:
