      Run all tests in parallel, giving each process ENV['TEST_ENV_NUMBER'] ('1', '2', '3', ...).

      Reports test results incrementally. Uses methods from `parallel_tests` gem to split files to groups.

      Source code of `turbo_tests` gem is based on Discourse and RubyGems work in this area (see README file of the source repository).

      Usage: turbo_tests [options]

      [optional] Only selected files & folders:
        turbo_tests spec/bar spec/baz/xxx_spec.rb

      Options:
    BANNER
