I’m attempting to upgrade a Rails 2.3.9 app to work with Ruby 1.9.2-p290; previously the app worked with Ruby 1.8.7. I’m noticing a few quirks, the most remarkable is that I cannot run any tests in my app — not individual tests and not rake tests.
minitest throws an error before any test is run:
undefined method `name' for ActionView::TestCase.
The full stack trace follows.
$ bundle exec rake test:units

It turns out that my gem environment was bad: I was using ruby 1.8.7, but my GEM PATHS were pointing to ruby 1.9.2.
