A selenium webdriver exception

Question

Today, when i use the selenium webdrive, i got an error. my platform is mac osx . this is my exception log.

ruby-1.9.2-p0 > Selenium::WebDriver.for :firefox
         


        

Answer 1

I've been using cucumber + capybara + webdriver + parallel_tests, & i've encountered the mentioned error. To resolve the issue, i added the following to features/support/env.rb:

unless (env_no = ENV['TEST_ENV_NUMBER'].to_i).zero?
  # Standard, which is described at the parallel_tests github page
  Capybara.server_port = 8888 + env_no

  # This successfully avoids locking port error, may require less, but
  # on my 8 cores vm, this works like a charm
  sleep env_no * 10
end

U probably need to adapt the above to fit what u use, the idea is just to force a sleep time to avoid starting all firefox instances at abt the same time, where a wait of 45secs may not be enough.
