Ruby on Rails, uninitialized constant Test::Unit::TestCase::Assertions (NameError)

Question

Like the headline said, I am getting the aforementioned error when I try to run my rspec tests. The exact error is (word wrapped for readability):

/.rvm/gems/ruby-1.9.3-p374/gems/test-unit-2.4.8/lib/test/unit/testcase.rb:93:in
 `<class:TestCase>': uninitialized constant 
   Test::Unit::TestCase::Assertions (NameError)

The main fix for this problem on the internet seems to be to remove the 'turn' gem, however I don't have the turn gem loaded. Here is my Gemfile:

source 'https://rubygems.org'

gem 'rails', '3.2.8'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'devise'
gem 'therubyracer'
gem 'mysql2'
gem 'cucumber'
gem 'email_spec'
gem 'cancan'
gem 'rolify'
gem 'libv8'
gem 'simple_form'

group :test, :development do
  gem 'rspec-rails'
  gem 'factory_girl_rails'
  gem 'test-unit'
end

group :test do
  gem 'cucumber-rails', :require => false
  gem 'capybara'
  gem 'database_cleaner'
end

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'coffee-rails', '~> 3.2.1'
  gem 'bootstrap-sass'
  gem 'sass-rails',   '~> 3.2.3'
  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

The part of my code that the test seems to be choking on is when I have this line in my require 'rspec/rails' in my rspec_helper.rb file.

This project used to run rspecs flawlessly. It's only when I did a reinstall of my OS that it began to behave badly.

Any help is greatly appreciated

Answer 1

Since your are not generating a new app, remove the line

gem 'test-unit'

from your Gemfile and remove the gems turn and minitest, followed by a bundle update.

Answer 2

Answer: If you look in my Gemfile, you see a requirement in my group :test, :development for gem 'test-unit'. I commented that out and it works like a charm. Why and how this works I have no idea, if someone would mind explaining go right ahead.
