【问题描述】：
WebMock 和 Selenium 的组合导致第一次调用 visit 时出现类型错误
Failure/Error: id['ELEMENT'] || id['element-6066-11e4-a52e-4f735466cecf']

但是，当我删除所有 WebMock 代码时，我的测试就会执行。我已经在我的 WebMock 异常中允许了 localhost，但是我的测试仍然无法执行。我不确定在使用 WebMock 时还需要做什么才能让 Selenium 运行。此外，如果 Selenium 规范是第一个运行的，它们就会通过。
水豚设置
Capybara.configure do |config|
config.run_server = false
config.app_host = root_url #retrieved elsewhere
Capybara.register_driver :chrome do |app|
Capybara::Selenium::Driver.new(app, browser: :chrome)
end
config.save_path = File.join Dir.pwd, 'tmp', 'capybara'
end
Capybara.default_driver = :chrome
Capybara.current_driver = Capybara.default_driver
Capybara.javascript_driver = Capybara.default_driver

发布错误消息的堆栈跟踪，以便我们查看它的实际来源。此外，我希望您意识到 WebMock 实际上不会让您模拟对来自浏览器的请求的响应，它只允许模拟您的应用程序发出的请求，并且通常不赞成使用应该是端到端的功能规范 (capybara) .
