如何解决试图让selenium在轨道上工作3-“ WebMock :: NetConnectNotAllowedError”
这是因为您正在使用webmock。它阻止所有出站HTTP请求。
如果不需要，请将其从Gemfile中删除。如果确实需要它，则可能需要根据需要更精确地配置它：

解决方法
我正在尝试在Rails 3应用程序中首次使用selenium。（我以前在导轨2上使用过它）。我在一个rvm中，它当然有它自己的gemset。
我首先用水豚跑了一个没有selenium的任务：
#./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
这样很好。然后，我在describe的选项中添加了“：js => true”选项，这应该使它使用selenium运行（据我所知）。并得到此错误：
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'=>'*/*','User-Agent'=>'Ruby'}).
to_return(:status => 200,:body => "",:headers => {})
============================================================
这是我第一次使用capybara，我认为我的配置有些错误。也许缺少一些必不可少的宝石？我正在关注此博客文章：使用RSpec＆Rails
3的Capybara（和Selenium）：快速教程
有任何想法吗？
PS，这是我的Gemfile内容：
