Problem/Motivation
#2469713-158: Step 2: Create a JavaScriptTestBase using PhantomJs Driver/Binary requires us to run just the javascript tests.
Proposed resolution
Possible solutions:
- Allow to filter by base class: Doesn't work because this requires reflection, which blows up on our codesize
- Expose the testsuite as flag. While this would work, it would add a new flag
- Map Phpunit test suites to simpletest groups and leverage the
--groupfunctionality. Changes how tests are grouped - Add a new
typekey to the simpletest information collected for each test class
