Problem/Motivation
run-tests.sh is pretty much the single most important piece of code in the Drupal QA process.
It's basically impossible to search for the string 'run-tests.sh' so it's difficult to be a dev who wants to work on it. :-)
This issue is one to use as a parent if you make an issue about run-tests.sh, in order to overcome the lack of searchability.
I've also taken the liberty of adding an issue tag for run-tests.sh, which might also help people find their way around.
