java - Organization of JUnit tests in projects

Question

What would you consider best practice for organizing JUnit tests in a project, and why? For example, do you keep your tests next to the classes they test? Do you put them in a separate but parallel package structure? Do you use a different organization strategy entirely?

Answer 1

I use a separate but parallel package structure for several reasons.

1. It keeps tests organized the same way as the application code.
2. I can easily build just the application files for distribution.
3. Test code still has access to my application code.
4. It's not as cluttered as having test code mixed with application code.
