I'm using a Rails 4 App with RSpec and Capybara.
My gemfile looks like:
source 'https://rubygems.org'
gem 'rails', '4.0.0'
gem 'pg'
gem 'devise'
gem 'sass-rails', '~> 4.0.0'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.0.0'
gem 'jquery-rails'
gem 'jquery-turbolinks'
gem 'turbolinks'
gem "rspec-rails", :group => [:test, :development]
group :test do
gem "factory_girl_rails", "~> 4.0"
gem "capybara"
gem "guard-rspec"
end
My spec_helper.rb file looks like:
require "capybara/rspec"
include Capybara::DSL
RSpec.configure do |config|
config.include Devise::TestHelpers, :type => :controller
config.extend ControllerMacros, :type => :controller
end
But for some reason I'm getting the error: uninitialized constant Devise (NameError)
. In my app, Devise is working correctly, though, and I have the ControllerMacros file in spec/support.
try this out:
your spec_helper should be like
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment",__FILE__)
require 'rspec/rails'
require "capybara/rspec"
include Capybara::DSL
RSpec.configure do |config|
config.include Devise::TestHelpers, :type => :controller
config.extend ControllerMacros, :type => :controller
end

I have Rails 4.2.5 and rspec 3.4.1
When I add render_views some first controllers test are failed.
I use render_views because I don't know any methods to watch what happens on a page.

If I call sign_in or sign_our methods tests are success.
You need to call the sign_in method before rendering as it check the current_user object and calls the authenticate! method on current_user object which is nil so throwing error!
Do it like this
before do
sign_in_user
end
this will set the current_user object.

I started a fresh new rails app (using rspec-rails 2.99 & capybara 2.3.0), and wrote a silly simple integration spec to get started with TDD:
# spec/integration/visit_home_page_spec.rb
require 'spec_helper'
feature "view the home page" do
scenario "user visits home page" do
visit root_path
expect(page).to have_content 'Password'
end
end
As expected, the test fails due to root_path being undefined - so I went ahead and:
# config/routes.rb
root 'users#new'
And here's the problem: instead of the spec failing due to UsersController being undefined, it's green. It appears that rspec is evaluating the error page itself, and since that page happens to contain the word "password", the spec passes.
To make sure that's what's happening, I have modified the spec to:
# spec/integration/visit_home_page_spec.rb
...
expect(page).to have_content 'theresnowaythisisinthepage'
...
Now the test fails, but not because it's picking up the undefined UsersController - just because the content is not in the error page.
I've started many an app with this approach, and it's the first time I've seen rspec mistaking an error page for a valid one - what did I break?
I suspect my forehead will have a big hand-shaped mark when I find the answer.

I am a newbie in Ruby on Rails, when I try method let in static_pages_specs.rb

Do you have any ideas what am I missing? I am using Ubuntu 13.04.
Edit: Already tried let bang method but it still gets the same error.
In the previous post I forgot to put
require 'spec_helper'
in, but my code actually DID have it.
Sorry about that but it was not actually the problem there.
Solved: Thank you guys I've just solved it, it was just a silly typing in one of my templates.
Your static_pages_specs.rb is missing require 'spec_helper':
require `spec_helper`
describe "Static pages" do
...
end
Please forgive any shortcomings in this (my first-ever) post on StackOverflow. I'm brand new to Ruby on Rails. I'm following the Rails Tutorial. I have spent many unsuccessful hours consulting other threads discussing the same Name Error that I'm raising in this question.
Any attempt of mine to run an rspec test like so: $bundle exec rspec spec/models/user_spec.rb
throws the now infamous error: `': uninitialized constant Rails (NameError)
Let me know if there's any more information I should provide you in order to get the ball rolling.

I have definitely run bundle install. I can also confirm that I've already created the database and run the migration (db/test.sqlite3 already exists)
In your spec_helper.rb, you have the following line twice:
Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}
Delete the first instance (the one on line 2). This is what is causing the error.
Having this line before require 'rspec/rails' will cause problems because we don't know what Rails is, and so we cannot call the root method.
The second instance (on line 13) is fine because this is after require 'rspec/rails'.
Remove redundant require 'spec_helper' line from your spec_helper.rb file.
