Actually, before we jump too fast. Based on your comment http://drupal.org/node/1717868#comment-6422150 I looked into the --verbose flag which I remember existing, but not to replace the simpletest_verbose variable.
--verbose Output detailed assertion messages in addition to summary.
Which is intended to spit out the individual row-by-row messages (assertions) in the output of the run-tests.sh script. Which is quite different from the simpletest_verbose variable which was to control the verbose page capturing functionality in DrupalWebTestCase.
We probably want to split these out and rename one. May also want to default to false on the command line? dunno.
I think --verbose flag as it stand now works the way that is most consistent with other scripts and makes sense. Perhaps we rename simpletest_verbose variable to 'capture' or something along those lines to 'capture browser shot' etc. I don't like those names just providing a thought basis.
If we default cli to false then using the cli then might do.
--print-details to print out assertion messages
Once committed http://drupal.org/node/1719530#comment-6427162 should be reverted.
