Tutorials for Unit-Testing in WordPress and for unit-test.svn.wordpress.org?

I’m starting to learn Selenium and PHPUnit and I am interested in implementing what I’ve learned in my WordPress projects. I’ve seen http://unit-test.svn.wordpress.org and wonder if there are any tutorials or core-developer’s notes on how to use it?

Resources on how to use the WordPress unit-test:

1. WordPress Automated Tests Trac

2. Automated Testing in The Codex

3. The Unit-Test README File (broken)

4. The PHPUnit Manual

5. Hakre/WP Unit-Tests Codex Page

6. Block Unit Test for Gutemberg

7. Unit Tests for WordPress Plugins
