Unable to connect to browser using ruby selenium webdriver

Asked 22/6, 2012 at 6:34 Answered 20/1, 2015 at 14:15

I tried to run some basic automated tests using ruby selenium webdriver. The same code works perfectly on my home computer, but fails on my work computer which is behind a proxy (which doesn't require authentication).

driver = Selenium::WebDriver.for :firefox, :profile => 'default'

The error I get is:

C:/Ruby193/lib/ruby/gems/1.9.1/gems/selenium-webdriver-2.24.0/lib/selenium/webdriver/remote/http/common.rb:66:in `create_response': unexpected response, code=

The browser opens with correct profile, but resulting driver variable is nil. I even tried to manually setup the proxy on the profile with no luck.

Any ideas ?

You probably have HTTP_PROXY (or http_proxy) set in your environment. The next release of selenium-webdriver (2.25) will also honor NO_PROXY/no_proxy (which you can then set to NO_PROXY=127.0.0.1). Until then you can remove the proxy from the Ruby environment before launching the browser:

ENV['HTTP_PROXY'] = ENV['http_proxy'] = nil
driver = Selenium::WebDriver.for :firefox

If you need the proxy configured for Firefox to communicate with the outside world, you could try something like this:

proxy = Selenium::WebDriver::Proxy.new(:http => ENV['HTTP_PROXY'] || ENV['http_proxy'])
ENV['HTTP_PROXY'] = ENV['http_proxy'] = nil
driver = Selenium::WebDriver.for :firefox, :proxy => proxy

I'm using selenium-webdriver 2.26.0, setting NO_PROXY=127.0.0.1 solved the problem. – Zoo 7/1, 2013 at 11:45

Usage of selenium-webdriver behind proxy has browser related specific. In short, you need to find a way of passing proxy settings to the browser instance created by webdriver.

Below is a code that works with Firefox.

#Firefox keeps proxy settings in profile.
profile = Selenium::WebDriver::Firefox::Profile.new
profile.proxy = Selenium::WebDriver::Proxy.new( :http => "192.168.1.1:3128")
driver = Selenium::WebDriver.for :firefox, :profile => profile

driver.navigate.to "http://google.com"
puts driver.title
driver.quit

-1

require 'rubygems'
require 'selenium-webdriver'
ENV['NO_PROXY']="127.0.0.1"
driver = Selenium::WebDriver.for :firefox
driver.get "http://google.com"
