Looking for an open source project to learn testing [on hold]

I have an assignment to learn testing and I'm looking for a project I could use, preferably a project that is implemented in Java programming language.

Here are some requirements, that we are supposed to test (doesn't have to be all of them):

1. Components testing (unit testing).
2. Integration testing.
3. Validation testing.
4. Acceptance / Qualification Testing
5. Software acceptance testing in order to ensure that its functionality matches end user expectations.
6. Installation Testing
7. Alpha and Beta Testing
8. Reliability Achievement and Evaluation
9. Regression Testing
10. Performance Testing
11. Security Testing
12. Stress Testing
13. Back-to-Back Testing
14. Recovery Testing
15. Interface Testing
16. Configuration Testing
17. Usability and Human Computer Interaction Testing

I was wondering if there was any open source project I could use for my assignment.
