title: How can I get color output in autotest using Test/Unit, MiniTest?
body: <p>Rails 3.2.1 app, using the minitest and autotest-rails gems.</p>
  
  <p>If I run "rake test" the output is in color.  But if I run autotest, the output is not in color.  </p>
  
  <p>How can I get color output when using autotest?</p>
  
  <p>Here's my test_helper.rb:</p>
  
  <pre><code>ENV["RAILS_ENV"] = "test"
  require File.expand_path('../../config/environment', __FILE__)
  require 'rails/test_help'
  require 'turn/autorun'
  
  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  = :pretty
   # turn on invoke/execute tracing, enable full backtrace
   c.trace   = true
   # use humanized test names (works only with :outline format)
   c.natural = true
  end
  
  class ActiveSupport::TestCase
    # Setup all fixtures in test/fixtures/*.(yml|csv) for all tests in alphabetical order.
    #
    # Note: You'll currently still have to declare fixtures explicitly in integration tests
    # -- they do not yet inherit this setting
    fixtures :all
  
    # Add more helper methods to be used by all tests here...
  end
  </code></pre>
