Similar to an existing discussion, but on Rails 3.1 with Ruby 1.9.2, I receive this error when trying to run tests from within RubyMine 3.2.4. Here's the full error:
/Applications/RubyMine 3.2.4.app/rb/testing/patch/testunit/test/unit/ui/teamcity/testrunner.rb:131:in `attach_to_mediator': uninitialized constant Test::Unit::UI::TestRunnerMediator::TC_TESTCOUNT (NameError)

from -e:1:in `load'

I tried regenerating the scripts that run the task but that didn't work. Any thoughts? Suggestions on how to fix?
