Where can I investigate junit tests in a real world project? [closed]

Question

What is a good open source project which uses junit tests in its source code? I want to see how its done and learn about it.

Answer 1

Any serious project (including open source) has unit tests. For what I've seen spring and hibernate have a lot of them.

This is a very good lecture about Object-oriented design for testability. It is not for complete beginners, but it gives very good insights.
