[RCD] state of unit tests

What is the current state of the unit tests? I am getting many failures of both the PHP and Selenium tests, but I was running them off on master, not a released version. Part of the problem was that I was hitting the 120 second PHP timeout that's hardcoded into iniset.php.
When you run the tests do you manually change that or is there some other way of running the tests that bypasses the execution timeout?

Are tests being added to and maintained? I've become used to test-driven development with jQuery, and it feels a little dirty to submit a bug or a pull request without a corresponding unit test.
