【问题描述】：
我收到主题中提到的一个问题，这是一个间歇性问题。然而，它使我们的 CI CD 管道变得不稳定，因此想从这个伟大平台上的极客那里获得一些帮助。
由于这是一个间歇性问题，我不希望升级我的浏览器版本，因为这主要是作为建议。
这里的详细信息可以帮助您确定我无法确定的原因
我使用什么库 -
gem 'selenium-webdriver', '3.6.0'
gem 'capybara', '2.18.0'
gem 'site_prism', '2.11'
我用什么浏览器-
Firefox - 52.8.0
我使用哪个操作系统 -
RHEL7
如何配置我的驱动程序 -
firefox_profile = Selenium::WebDriver::Firefox::Profile.new
firefox_profile['browser.download.dir'] = '/tmp'
firefox_profile['browser.download.folderList'] = 2
# content-type of file that will be downloaded
firefox_profile['browser.helperApps.neverAsk.saveToDisk'] = 'application/json;application/octet-stream;application/csv;text/csv;application/zip;application/x-zip;application/x-zip-compressed;application/x-rpm;application/pdf;application/xml;application/x-x509-ca-cert'
firefox_profile['timeout'] = 480000
firefox_profile['pdfjs.disabled'] = true
firefox_profile['resynchronization_timeout'] = 90
firefox_profile['resynchronize '] = true
firefox_profile['dom.max_chrome_script_run_time'] = 0
firefox_profile['dom.max_script_run_time'] = 0
Capybara.default_selector = :css
Capybara.ignore_hidden_elements = true
reset_wait_time
Capybara.run_server = false
client = Selenium::WebDriver::Remote::Http::Default.new
client.timeout = 240
if ENV['LOCAL'] == 'true'
STDOUT.puts 'starting local run'
Capybara.default_driver = :firefox
Capybara.register_driver :firefox do |app|
begin
STDOUT.puts 'Attempting to create browser instance'
Capybara::Selenium::Driver.new(app, browser: :firefox, profile: firefox_profile, marionette: false, http_client: client)
rescue => e
STDOUT.puts 'Error: Failed Attempting to create browser instance'
STDOUT.puts e
STDOUT.puts e.backtrace
end
end
begin
page.driver.browser.manage.window.resize_to(1200, 1200)
rescue => e
STDOUT.puts 'Error: Failed resize browser'
STDOUT.puts e
STDOUT.puts e.backtrace
end
end
错误堆栈跟踪 -
starting local run
Attempting to create browser instance
Error: Failed resize browser
unable to obtain stable firefox connection in 60 seconds (127.0.0.1:7055)
