Capybara patch to avoid `'about:blank')` which hangs sometimes.
# Monkey-patch on Capybara!!!
class Capybara::Selenium::Driver < Capybara::Driver::Base
# Patch to avoid `'about:blank')` which hangs sometimes.
def reset!
# Use instance variable directly so we avoid starting the browser just to reset the session
if @browser
begin @browser.manage.delete_all_cookies
rescue Selenium::WebDriver::Error::UnhandledError
# delete_all_cookies fails when we've previously gone
# to about:blank, so we rescue this error and do nothing
# instead.
# about:blank is broken for this purpose. Use app's /ping"#{Capybara.app_host}/ping")
