rails--rails/railties/test/application/test_runner_test.rb
Kasper Timm Hansen b6fc8e25a1 Improve test runner's Minitest integration.
This also adds free mix and matching of directories, files and lines filters.
Like so:

bin/rails test models/post_test.rb test/integration models/person_test.rb:26

You can also mix in a traditional Minitest filter:

bin/rails test test/integration -n /check_it_out/
