Minitest Integration

To use the OSC Progress reporter with Minitest, require the integration file in your test_helper.rb:

require "osc/progress/integrations/minitest" if STDOUT.isatty

This will automatically register the reporter.

To test the integration, you can run the following command:

DEMO=1 rake test
