minitest-reporters - create customizable MiniTest output formats StillMaintained Status Build Status

Death to haphazard monkey-patching! Extend MiniTest through simple hooks.


gem install minitest-reporters


In your test_helper.rb file, add the following lines:

require 'minitest/reporters'
MiniTest::Unit.runner =
MiniTest::Unit.runner.reporters <<

Now, just run your tests; the reporter you specified will be used and make your output look absolutely gorgeous! If you feel the need to write your own reporter, just include MiniTest::Reporter and override the methods you'd like. Take a look at the provided reporters for examples.

The following reporters are provided:

MiniTest::Reporters::DefaultReporter # => Identical to the standard MiniTest reporter
MiniTest::Reporters::SpecReporter # => Turn-like output that reads like a spec
MiniTest::Reporters::ProgressReporter # => Fuubar-like output with a progress bar
MiniTest::Reporters::RubyMateReporter # => Simple reporter designed for RubyMate; see below

I really like ProgressReporter for my everyday terminal usage, but I like using RubyMateReporter when I'm executing test suites from TextMate. My usual set up looks like this:

require 'minitest/reporters'
MiniTest::Unit.runner =
if ENV['TM_PID']
  MiniTest::Unit.runner.reporters <<
  MiniTest::Unit.runner.reporters <<


  • Make the boilerplate code look prettier. Something like a one-line require for the general use-case would be nice.
  • Add some example images of the reporters.

Note on Patches/Pull Requests

  • Fork the project.
  • Make your feature addition or bug fix.
  • Add tests for it. This is important so I don't break it in a future version unintentionally.
  • Commit, but do not mess with the Rakefile. If you want to have your own version, that is fine but bump the version in a commit by itself in another branch so I can ignore it when I pull.
  • Send me a pull request. Bonus points for git flow feature branches.
