I can't make Capybara to work in many of my integration tests.
When I visit certain pages, I get the following html:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
And so when I try to use the have_content() selector, it raises the following error:
Failure/Error: page.should have_content("HELLO")
Capybara::ElementNotFound:
Unable to find xpath "/html"
Some of the pages of my apps I can visit just fine, but some other ones I can't. There are even some pages that work at some places, and not at others:
require 'spec_helper'
describe HomeController do
it "shows the website description" do
visit root_path
puts page.html.length # ==> 108 (no html)
...
end
end
require 'spec_helper'
describe FlowsController do
it "should do stuff" do
visit root_path
puts page.html.length # ==> 4459, works even if the exact same one didn't work in home_controller_spec!
visit flows_path
puts page.html.length # ==> 3402, works
visit new_user_session_path
puts page.html.length # ==> 3330, works
within("form#new_user") do
fill_in 'Email', :with => 'email#example.com'
fill_in 'Password', :with => 'password'
click_on 'Sign in'
end
puts page.html.length # ==> 108, No html
end
end
I read in this post that this was an error that might occur when using Capybara and webrat at the same time. But I'm not using webrat at all, and I still get the error...
Here is my Gemfile:
source 'https://rubygems.org'
gem 'rails', '3.2.6'
gem 'pg'

Digging up online suggested putting config.include Capybara::DSL in spec/spec_helper.rb. I did that and didn't work. Another suggestion said I need to move my static_pages_spec.rb to spec/features. I did that and that didn't work either.
Help? :D
visit is a method used in feature specs.
In your request specs you instead use the HTTP verbs get, post, patch etc to send http requests.
require 'rails_helper'
RSpec.describe "Static pages" do
describe "Home page" do
it "should have the content 'Sample App'" do
get '/static_pages/home'
expect(page).to have_content('Sample App')
end
end
end
I believe you are using a badly outdated tutorial as well as subject.should has been depreciated for a long time in favor of
expect(subject).to.
While you can mix capybara into your request specs it may be better to use request specs as a low level integration tests and leave the higher level clicking and button pushing to your feature specs.
When you run into trouble you might want to refer to the official RSpec-rails documentation instead.

If anyone can get me pointed in the right direction, it would be greatly appreciated. I prefer to stick to solutions closest to the books methods but if I have to do something differently to get this to pass and proceed onwards then I'll take what I can get. Just please to don't suggest me doing anything crazy advanced that I clearly should be getting into yet if at all possible. Thanks. Simple is better here.
You're using RSpec and Capybara matchers in your spec, but you don't have those gems installed.
Here is the Gemfile from the 2nd edition:
Gemfile
source 'https://rubygems.org'
gem 'rails', '3.2.16'
group :development, :test do
gem 'sqlite3', '1.3.5'
gem 'rspec-rails', '2.11.0'
end
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '3.2.5'
gem 'coffee-rails', '3.2.2'
gem 'uglifier', '1.2.3'
end
gem 'jquery-rails', '2.0.2'
group :test do
gem 'capybara', '1.1.2'
end
group :production do
gem 'pg', '0.12.2'
end
Looking at your Gemfile, it appears you're using a newer version of Rails. If you are following Michael's tutorial, you should use the same versions that he specifies. There is a newer edition of the tutorial available, suited for Rails 4 development. You can read it here for free:
https://www.railstutorial.org/book
I am trying to get to grips with Rails and Rspec for testing using Capybara. I’m currently trying to test for uniqueness of a Profile Name for User. However from reading around fixtures should not be used with Rspec. How do I go about adding some base data for me to test against.

Use factory_girl_rails gem.
factory_girl_rails provides Rails integration for factory_girl
which is a fixtures replacement with a straightforward definition
syntax, support for multiple build strategies (saved instances,
unsaved instances, attribute hashes, and stubbed objects), and support
for multiple factories for the same class (user, admin_user, and so
on), including factory inheritance.
Create a folder under spec directory as factories.
In spec_helper.rb,
RSpec.configure do |config|
config.include FactoryGirl::Syntax::Methods ## Add only this line
end
Create factory files under spec/factories directory and define the required factories
as shown in Factory Girl Documentation
In your spec files, use the defined factories as shown here
I am working through Hartl's Ruby on Rails tutorial and am trying to test for user signups with invalid information and am getting a "Load Error" when running rspec. I am unsure how to fix this error, as I have updated my gem files.

I notice that it is empty, however, the tutorial's steps did not require any changes.
Your error says the framework cannot load the file "/Users/kelvinyu/rails_projects/sample_app/signup with invalid information" which clearly isn't a file—the file is "spec/requests/user_pages_spec.rb". Try having everything in one line—without the \ > (this slash angle bracket only means that there, maybe, was a line break when Michael Hartl was typing up the tutorial.
Also, look to using describe and context interchangeably. This would make you write clearer specs. There is no magic to it. The sourcecode for RSpec shows that context is just another name for describe. But when you write specs with both, the meanings are clearer.
I am following the tutorial from Michael Hartl . I tried the first test example for testing the app with Rspec and when I execute this command "bundle exec rspec spec\requests\static_pages_spec.rb" I get this error.

You need to require 'spec_helper' in your spec source.
Your spec_helper should include both rspec/rails and capybara/rails in it.
You'll want to use get instead of visit if you want to access the response, however.
If static_pages_spec.rb has string require 'spec_helper' and you get
Failure/Error: visit '/static_pages/home'
add to spec_helper.rb string config.include Capybara::DSL
it helped me
