Rails 3.2: Switching from Rspec to Test::Unit

1
votes

I created a new Rails 3.2.x application with the -T option for no tests because I wanted to use Rspec for testing.

Now I want to revert it back to Test::Unit. How can I do that such that all of the rake tasks work, and new scaffolds are generated with Test::Unit instead of RSpec test shells?

After searching and hacking, here is what got it to work for me.

  1. Remove rspec and rspec-rails from the Gemfile
  2. Run "gem list rspec --local", and do a "gem uninstall" for each of those rspec gems.
  3. Delete Gemfile.lock
  4. rm -r spec/
  5. bundle install
  6. mkdir test/
  7. Add "require 'rails/all'" to config/application.rb

  8. Create a file test/test_helper.rb and put the following code in it:

    ENV["RAILS_ENV"] = "test"
require File.expand_path('../../config/environment', __FILE__)
require 'active_support'
require 'rails/test_help'
# require 'factory_girl_rails'  #use if you are using FactoryGirl for fixtures

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

After that, you can generate tests using

rails g integration_test SomeStories

Or you can just add unit tests under test/unit and then run them with

rake test
rake test:recent
