Trying to get selenium working in rails 3 - “WebMo

Question

I'm trying to use selenium for the first time in a rails 3 app. (I've used it before with rails 2). I'm in an rvm which of course has its own gemset.

I first ran a task with capybara, without selenium:

#./spec/requests/homepage_spec.rb
require 'spec_helper'

describe 'home page', :type => :request do
  it 'should welcome the user' do
    visit '/'
    page.should have_content('Buddy')
  end
end

This ran fine. I then added a ":js => true" option to the options for describe, which is supposed to make it run using selenium (as far as i know). And got this error:

 Failure/Error: @page.start_new_browser_session
 WebMock::NetConnectNotAllowedError:
   Real HTTP connections are disabled. Unregistered request: POST http://localhost:4444/selenium-server/driver/ with body 'cmd=getNewBrowserSession&1=%2Afirefox&2=http%3A%2F%2Flocalhost%3A3000&3=&4=' with headers {'Accept'=>'*/*', 'Content-Type'=>'application/x-www-form-urlencoded; charset=utf-8', 'User-Agent'=>'Ruby'}

   You can stub this request with the following snippet:

   stub_request(:post, "http://localhost:4444/selenium-server/driver/").
     with(:body => "cmd=getNewBrowserSession&1=%2Afirefox&2=http%3A%2F%2Flocalhost%3A3000&3=&4=", 
          :headers => {'Accept'=>'*/*', 'Content-Type'=>'application/x-www-form-urlencoded; charset=utf-8', 'User-Agent'=>'Ruby'}).
     to_return(:status => 200, :body => "", :headers => {})

   ============================================================

It's my first time using capybara and i think my config is just wrong somehow. Maybe missing some essential gems? I was following this blog post: Capybara (and Selenium) with RSpec & Rails 3: quick tutorial

Any ideas?

PS, here's my Gemfile contents:

Answer 1

Good suggestions here. Another, more fine-tuneable, solution:

WebMock.disable_net_connect!(
  allow: [
    'localhost',
    'dynamo:8000',
    'pact-broker:81'
  ]
)

Works especially well for whitelisting docker-compose containers!

Answer 2

In my specific case my problem was in evergreen (javascript rspec).

I added:

WebMock.disable_net_connect! :allow_localhost => true

To my environments/env*.rb because evergreen doesn't load rspec helpers.

Answer 3

WebMock.disable_net_connect! allow_localhost: true

Answer 4

I tried the above answers and none of them worked, then found that the issue was my workplace's Internet connection. It worked on my home's Internet connection.

Answer 5

It's because you are using webmock. It blocks all outbound HTTP requests.

If you don't need it, remove it from the Gemfile. If you do need it, then you may need to configure it more precisely to your needs:

Answer 6

With this...

WebMock.disable_net_connect!(:allow_localhost => true)

you allow real web access to your localhost. It's perfect when you need to use Selenium for you application and, at the same time, mock external resources.
