Migrate from Rspec to Minitest with Rails
New Rspec has released, with lots of DSL changes. Every rspecer is painfull. ^_^
Minitest is so lightweight, cute and simple. Why was I so stuip to choose Rspec?
This article will show you how to migrate from rspec to minitest.
Gemfile
Add ‘minitest_rails’ and ‘mocha’ to gemfile
# Rails4 use minitest as default testing framework, if your rails version is greater than 4.0, you can skip this step.
gem "minitest"
gem "minitest-rails"
MiniTest::Mock is not so power, we use Mocha instead.
gem "mocha", :require => false
Gem Turn is great way to view test results. you can see exact result of every test (Success, Faiure and Why).
gem "turn", :require => false
test_helper.rb
-
After installed ‘minitest-rails’, you can run
rails generate minitest:installto add test_helper.rb to the test directory. -
require
require "minitest/autorun"
require "minitest/rails"
require "mocha/setup"
FactoryGirl
Don’t worry. Factory can find all the factories under spec/. old factories will be load when you run rake test. But you’d better put new factories into test/.
Rakefile
Add pattern in you Rakefile, additional testing tasks defined in “test/*/_test.rb” will be evaluated when you run Rake test
Rake::TestTask.new do |t|
t.libs << "test"
t.test_files = FileList['test/**/*_test.rb']
t.verbose = true
end
Bingo, it works
run rake test
