Restart phantomjs when it hangs

# Borrowed from https://github.com/y310/rspec-retry/blob/master/lib/rspec/retry.rb

CAPYBARA_TIMEOUT_RETRIES = 3

RSpec.configure do |config|
  config.around(:each, type: :feature) do |ex|
    example = RSpec.current_example
    CAPYBARA_TIMEOUT_RETRIES.times do |i|
      example.instance_variable_set('@exception', nil)
      self.instance_variable_set('@__memoized', nil) # clear let variables
      ex.run
      break unless example.exception.is_a?(Capybara::Poltergeist::TimeoutError)
      puts("\nCapybara::Poltergeist::TimeoutError at #{example.location}\n   Restarting phantomjs and retrying...")
      restart_phantomjs

def restart_phantomjs
  puts "-> Restarting phantomjs: iterating through capybara sessions..."
  session_pool = Capybara.send('session_pool')
  session_pool.each do |mode,session|
    msg = "  => #{mode} -- "
    driver = session.driver
    if driver.is_a?(Capybara::Poltergeist::Driver)
      msg += "restarting"
      driver.restart
    else
      msg += "not poltergeist: #{driver.class}"

I pasted the above code in support directoryThe above code didnt work. Still I can see Timed out waiting for response to {"name":"visit","args":["http://ankakade-portal.dev.bluecloud.ibm.com:3000/server_requests/new"]}. It's possible that this happened because something took a very long time (for example a page load was slow). If so, setting the Poltergeist :timeout option to a higher value will help (see the docs for details). If increasing the timeout does not help, this is probably a bug in Poltergeist - please report it to the issue tracker. (Capybara::Poltergeist::TimeoutError)

I have set the CAPYBARA_TIMEOUT_RETRIES = 3
