Why are tests running in production mode and causing my script/runners to fail?

So I have some script/runners set up in a cron job, but according to the logs, I'm getting this error below. First, I'm not sure why Test::Unit automatic runner is happening in production to begin with. I don't have autospec or autotest going on. Secondly, I'm not sure how to resolve this pesky invalid option error. I'm using the javan-whenever gem to handle the cron schedule. Any help out there?

This is because something in your environment is requiring Test::Unit. I was having the same problem running rails runner in a Rails 3.1.0 application, and it was because we had gem test-unit in our Gemfile for all groups, rather than just for the test group where it was actually needed. Once I moved it into the test group, my runners ran as expected.

This code seems to be the culprit:

# test_unit/lib/test/unit.rb
at_exit do
  unless $! || Test::Unit.run?
    exit Test::Unit::AutoRunner.run
  end
end

If you can't remove the requirement on Test::Unit, you can add this hack somewhere in your environment to prevent AutoRunner from auto-running:

Test::Unit.run = true
