Maven, junit and Mock Classes

I have have (again) a design question, where to place "Mock" Classes for
junit.

Example:

project-core (depends project-dao)
        public TestSomeCoreFunctions {
                DAO dao = new MockDAO();
                ...
        }


project-dao
        public interface dao {
                public AccessObject1 do();
        }

        public interface AccessObject1 {
        
        }



 
project-another module (depends project-core)
        public TestSomeThing {
                DAO dao = new MockDAO();
                AccessObject1 ao = new MockAccessObject();
                ...
        }

So where can I put both Mock Objects?

Obviously not in the dao, because testclasses are not dependencies.
So I would end up with a project for each or all MockObjects.

project-dao-mock (depends project-dao)
        public class MockAccessObject implements AccessObject1..


This means in turn, that I COULD NOT use the mock objects in the project-dao
(circular dependencies), but I NEED them for my junit tests...

So what? I'm confused ;-)

You could use the test jar mojo:

That directory is not available as dependency.

Mock classes can stay in the src/test/java directory. What's the problem?

You may specify the test-classes as a dependency using the test-jar
mojo of the jar plugin:
http://maven.apache.org/plugins/maven-jar-plugin/test-jar-mojo.html

Using this, you'll have jars containing the test-classes which will be
available using the "tests" classifier

Using that technique, it is possible to place your mock-objects inside
project-dao (or project-core, if the class-level dependencies allow
you to do so).

hope that helps.


Francois
