rails Devise authenticated routes in integration test

问题

I want to test every route in an application, and learned I should do that in an integration test: Where to test routes in ruby on rails

However I'm getting the following error:

NoMethodError: undefined method `authenticate?' for nil:NilClass
/usr/local/Cellar/ruby/1.9.3-p194/lib/ruby/gems/1.9.1/gems/devise-2.1.2/lib/devise/rails/routes.rb:286:in `block in authenticated'

It's well-mentioned online that you can't use Devise::TestHelpers in integration testing -- Devise Google Group, Devise Github page

How can I test routes like the following?

# config/routes.rb

devise_for :users

authenticated :user do
  root to: 'static#home'
end

root to: 'static#landing'

I am running test unit tests with $ rake test:integration

Integration tests are important for your application work flow. They can tell about your URL definition more clearly.

Check the post by nicholaides, that explains the cause of this error and the solution in Authenticated routes.

Still the problem is:

Devise has its own methods and you can't use Devise::TestHelpers in ruby. So how can you test? Well you need to include the Devise::TestHelpers somehow.

Well, if you're using RSpec, you can put the following inside a file named spec/support/devise.rb:

RSpec.configure do |config|
  config.include Devise::TestHelpers, :type => :controller
end

This is specified here.

But wait.......... Again, you can run into this same issue with Test::Unit.

Then?

So, you just need to add the devise test helpers to test/test_helper.rb.

class ActiveSupport::TestCase
  include Devise::TestHelpers
end

Devise::TestHelpers work by putting things directly into your session. When running integration tests with Capybara, you don't have access to the server-side session. You just have access to the browser.

In our application, our integration tests use helper methods like this, that interact with Devise through the user interface:

def authenticate(user, password = nil)
  password ||= FactoryGirl.attributes_for(:user)[:password]
  visit new_user_session_path
  fill_in 'email', with: user.email
  fill_in 'password', with: password
  click_on 'Login'
  expect(current_path).to eq welcome_path
end
