Question

I’m trying to test my Rails 3.2.3 application by RSpec. It’s installed (I already tested another application and it worked well) but it doesn’t exist in Gemfile. Here is the code of spec/application_controller_spec.rb

    require "rspec"
    require_relative "../app/controllers/application_controller"

    describe ApplicationController do
      it "current_cart does something" do
        #app_controller  = ApplicationController.new
        pending
      end
    end

The following command returns an error:

alex@ubuntu:~/RubymineProjects/psg$ rspec spec
/home/alex/RubymineProjects/psg/app/controllers/application_controller.rb:1:in `<top (required)>': uninitialized constant ActionController (NameError)

    from /home/alex/.rvm/gems/ruby-1.9.3-p194/gems/rspec-core-2.11.1/lib/rspec/core/runner.rb:8:in `block in autorun'

The file ApplicationController.rb

 class ApplicationController < ActionController::Base
   def some_action
     #............
   end

end

Even when I add gem 'rspec' in Gemfile it won’t change anything, the error will remain.

Any thoughts?

What is this require_relative doing there? I use rspec and don’t need this. Actually the only require in my spec files is:

require 'spec_helper'

(At least in most cases, there are a few files that require special stuff like “authlogic/test_case”)

My Gemfile entry for rspec looks like this:

group :development do
  gem 'rspec-rails'
end

group :test do
  gem 'rspec-rails'
  gem 'spork', '0.9.0.rc8'
end

You won’t need spork if you don’t use it of course, but maybe the “rspec-rails” instead “rspec” could be your problem.
