Where can I find open source web application implementations online that contain (mostly) complete unit test suites in Java?

Question

I work for a large enterprise, and my team's unit test practices and coverage leave something to be desired. I picked up copies of xUnit Test Patterns: Refactoring Test Code and Working Effectively with Legacy Code, but I would really like to see some full example test suites for existing applications. Specifically, I'm looking for the following:

• Open source (so I can look at the code and the test cases)
• The application under test is a web app. (Not a web app framework. I want to see something with some business logic in it.)
• Written in Java, so JUnit or TestNG are both fine.

I've dug around on Github, but so far the vast majority of the Java apps I come across are Android apps or have no test suites.

Have a look at this https://github.com/testinfected/petstore/ - it's a Spring/Hibernate pet store web app using the ideas in the http://www.growing-object-oriented-software.com/ book.
