我收到主题中提到的问题，这是一个间歇性问题。但是，它使我们的CI CD管道不稳定，因此可以从这个出色的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，因此我不希望升级我的浏览器版本，因为它主要是作为建议而提及它。
以下是一些详细信息，可以帮助您确定我无法找到的原因
我使用什么库-
gem 'selenium-webdriver', '3.6.0'
gem 'capybara', '2.18.0'
gem 'site_prism', '2.11'
我使用什么浏览器-
Firefox - 52.8.0
我使用哪个操作系统-
RHEL7
如何配置驱动程序-
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-

Attempting to create browser instance
Error: Failed resize browser

答案 0 :(得分：1)
我知道您说过您不想被告知要更新浏览器版本，但是解决方案实际上将花费时间来更新所有测试项目。您提到的每个宝石的版本都已过时，此后所有提及的宝石都进行了大量的稳定性和时序改进。
从技术上讲，您实际上正在运行的Firefox版本从未真正使用本机Firefox驱动程序得到Selenium的支持，因为Selenium那时已开始专注于WebDriver（geckodriver）。真正的解决方案实际上是更新。
