Better minitest output with turn gem.

This is a short post about using turn gem with MiniTest::Spec and Rails 3.1 for better output.

Add to your Gemfile:

group :test do
  gem 'turn'
end

Don't forget to run bundler against your new Gemfile content:

$ bundle install

Assuming you have this in your test file:

require "minitest_helper"

Add to your test/minitest_helper.rb:

Turn.config do |c|
 # use one of output formats:
 # :outline  - turn's original case/test outline mode [default]
 # :progress - indicates progress with progress bar
 # :dotted   - test/unit's traditional dot-progress mode
 # :pretty   - new pretty reporter
 # :marshal  - dump output as YAML (normal run mode only)
 # :cue      - interactive testing
 c.format  = :outline
 # turn on invoke/execute tracing, enable full backtrace
 c.trace   = true
 # use humanized test names (works only with :outline format)
 c.natural = true
end

Now, you can run your tests and enjoy chosen output format:

$ rake test
