Unable to connect to browser using ruby selenium webdriver

ruby, selenium, webdriver

Solution

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

Problem

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= 403, content-type="text/html" (Selenium::WebDriver::Error::WebDriverError) <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <HTML><HEAD><META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=iso-8859-1"> <TITLE>ERROR: The requested URL could not be retrieved</TITLE> <STYLE type="text/css"><!--BODY{background-color:#ffffff;font-family:verdana,sans-serif}PRE{font-family:sans-serif}--></STYLE> </HEAD><BODY> <H1>ERROR</H1> <H2>The requested URL could not be retrieved</H2> <HR noshade size="1px"> <P> While trying to retrieve the URL: <A HREF="http://127.0.0.1:7055/hub/session">http://127.0.0.1:7055/hub/session</A> <P> The following error was encountered: <UL> <LI> <STRONG> Access Denied. </STRONG> <P> Access control configuration prevents your request from being allowed at this time. Please contact your service provider if you feel this is incorrect. </UL> ``` 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 ?
