Where do I put my stubs?

I've been utilizing stub implementations of my abstract classes for testing purposes. Currently, my unit tests are residing in a test directory alongside my src directory.

I'm wondering if there is a best-practice for where to place any stubs that are used in the testing. I have been trying several things, but part of me seems to be perpetually perturbed no matter what I do.

Things I have tried:

Bear in mind, I am probably over-thinking this. Is there any information on best-practices that could put my mind to rest? Is switching to a mock framework a solution to this dilemma?

Much appreciated.

The 3rd option is definitely better than the other two for the reasons you've given. I like to refer to the Maven directory structure during times like this, and it doesn't seem to imply anything different than your 3rd option.

What I do is create the stub as an inner class inside the test itself. Once this gets too messy or needs to be reused, I put the stubs in the same package as the abstract class, but under the test directory.

It might be worth knowing that a lot of projects evolve to have "Builder" objects that work like this:

Person person = new PersonBuilder().withName("John Doe").withDefaultAddress().build();

The reason you do this is because sometimes a Person needs to be created lots of different ways depending on what you're testing. Having just one PersonStub may not be enough.
