ruby - Timeout::Error using selenium-webdriver in ruby

Question

I have been getting a Timeout error ever since I started developing my tests. At first I thought it was related to the efficiency of my xpaths but after seeing the test pass quickly numerous times I don't think it is related to the selectors. The error randomly occurs and often when it does it occurs multiple times within a feature. I need to fix or at least understand what this problem is.

An example of a step definition:

When /^I navigate to "(.*)"$/ do |webpage|
navigate_to(webpage)
end

This is the error I get:

 Timeout::Error (Timeout::Error)
      /usr/lib/ruby/1.9.1/net/protocol.rb:146:in `rescue in rbuf_fill'
      /usr/lib/ruby/1.9.1/net/protocol.rb:140:in `rbuf_fill'
      /usr/lib/ruby/1.9.1/net/protocol.rb:122:in `readuntil'

      /usr/lib/ruby/1.9.1/net/http.rb:2562:in `read_status_line'
      /usr/lib/ruby/1.9.1/net/http.rb:2551:in `read_new'
      /usr/lib/ruby/1.9.1/net/http.rb:1319:in `block in transport_request'
      /usr/lib/ruby/1.9.1/net/http.rb:1316:in `catch'
      /usr/lib/ruby/1.9.1/net/http.rb:1316:in `transport_request'
      /usr/lib/ruby/1.9.1/net/http.rb:1293:in `request'
      /usr/lib/ruby/1.9.1/net/http.rb:1286:in `block in request'
      /usr/lib/ruby/1.9.1/net/http.rb:745:in `start'
      /usr/lib/ruby/1.9.1/net/http.rb:1284:in `request'
      ./features/support/env.rb:88:in `block in get_page_url'

The env.rb :

require 'selenium-webdriver'
require 'rubygems'
require 'nokogiri'
require 'rspec'
require 'rspec/expectations'
require 'httpclient'
require 'fileutils.rb'
require 'pathname'

$driver = Selenium::WebDriver.for :ie
#accept_next_alert = true
$driver.manage.timeouts.implicit_wait = 300
$driver.manage.timeouts.script_timeout = 300
$driver.manage.timeouts.page_load = 300
#verification_errors = []

AfterStep do
 sleep 5
end

at_exit do
    $driver.close
end

I have gone through numerous questions about this very same topic and none seem to have an answer that works, if an answer at all.

Similar issue. I have tried the solutions provided here but my error still persist https://www.ruby-forum.com/topic/4414675

I have tried adding explicit waits as such: http://docs.seleniumhq.org/docs/04_webdriver_advanced.jsp

I need to get this issue sorted out so please ask questions if I wasn't clear on anything.

自发布此消息以来，我已经编辑了 env.rb 并更新了问题的那一部分。这可能不是绝对的解决方法，但我注意到对我来说已经解决了部分问题。

我将 env.rb 中的超时时间从 300 更改为 20。

$driver.manage.timeouts.implicit_wait = 20
$driver.manage.timeouts.script_timeout = 20
$driver.manage.timeouts.page_load = 20

这样做后，我的测试套件现在执行得更快，而不是冗长的超时错误，我得到了与我的代码有关的真正错误（糟糕的选择器，错误的方法等）。

我过去常常因为简单地导航到一个页面而得到的超时现在变成了：

 Timed out waiting for page to load. (Selenium::WebDriver::Error::TimeOutError)

不到 20 秒就出现了，但这可能是由于我与网页的连接。我将在不久的将来更多地研究这个错误。

如果有人尝试这个，请告诉我它是如何为你工作的（即使它没有）。随着我了解更多，我将继续更新此内容。

论坛上有关于这个问题的Ruby讨论。

对于 2013 年 7 月 19 日，似乎没有修复它，但有一个建议是延长失败前的时间：

 driver.manage.timeouts.page_load = 300 # 5 minutes

我在使用 watir-webdriver 时遇到了这个错误，就我而言，我试图访问：

@browser.goto "localhost:3000/#/login"

当我应该访问时：

@browser.goto "http://localhost:3000/#/login"

奇怪的是，我调用此方法的第一个场景有效，但是在我的第二个场景中尝试导航相同的 URL 时，我收到了与您的类似的堆栈跟踪

尝试在您的 Rails 应用程序中删除位于 tmp/cache 中的缓存文件夹，并在应用程序的根目录下运行“rake assets:clean:all”

与其他浏览器相比，Internet Explorer 的 xpath 问题更多。我曾经使用 webdriver 和 java 遇到过这个问题。您是否尝试过使用 css 选择器实例化 Selector 并查看这是否有助于浏览器定位元素？

我现在使用硒进行刮擦而不是测试，我正在处理这样的事情：

browser_name = :chrome
http_client = Selenium::WebDriver::Remote::Http::Default.new(open_timeout: 5.minutes, read_timeout: 5.minutes)
@browser = Watir::Browser.new browser_name, http_client: http_client
