如何使用 lib minitest 或 Test:Unit 为单元测试着色？

Question

I would like to have unit tests output color in my dev environment. However, I can't make it work on Linux (Debian and Ubuntu). When I include the following libs:

require 'minitest/autorun'
require 'minitest/unit'
require 'minitest/pride'

I get:

/usr/local/rvm/gems/ruby-1.9.2-p136/gems/minitest-2.3.1/lib/minitest/pride.rb:35:in `<top (required)>': undefined method `output' for MiniTest::Unit:Class (NoMethodError)

caused by the code:

MiniTest::Unit.output = PrideIO.new(MiniTest::Unit.output)

I have seen a working Rspec variant . Unfortunately, my Ruby knowledge is not enough to see differences.

Answer 1

Give turn a whirl.

Add this to your Gemfile:

group :test do
  gem 'turn', :require => false
end

Answer 2

step 1: use the latest version of the gem (I think it will be fixed in Ruby 1.9.3)

gem install minitest

step 2: require "minitest/pride" on the command line, not in your code

ruby -rminitest/pride your_ruby_script.rb

.. and in your code simply require 'minitest/autorun'

require 'minitest/autorun'

If you use Rubymine, just add

-rminitest

in the default configuration of the tests. => the configuration would like

-e $stdout.sync=true;$stderr.sync=true;load($0=ARGV.shift) -rminitest/pride

Answer 3

simply add these lines to your test_helper.rb file after require 'rails/test_help'

require "minitest/reporters"
Minitest::Reporters.use!

in your gemfile add

gem 'minitest-reporters', '~> 1.0.7'

this will get your rake test to be in red and green, but it also brings up the backtrace. to get rid of all those extra backtrace logs add this to your gemfile then bundle:

gem 'mini_backtrace'

then in config/initializers/backtrace_silencers.rb add this line to cut all the extra rvm stuff

Rails.backtrace_cleaner.add_silencer { |line| line =~ /rvm/ }

hope that works for you, let me know if you need more details.

Answer 4

See https://github.com/tenderlove/purdytest/issues/1 . It seems to be a known bug with the minitest version shipped with 1.9.2. For the others, adding

gem "minitest"

at the very top of your file did the trick.

Answer 5

I currently use purdytest with 1.9.2

Answer 6

Try look at this post about using turn gem for nice looking and configurable output for minitest. http://rawonrails.blogspot.com/2012/01/better-minitest-output-with-turn-gem.html

Answer 7

$ gem install mynyml-redgreen --source http://gemcutter.org

# in your test file
require 'redgreen'

redgreen and turn work nicely in conjunction with each other, by the way
