我在运行Selenium测试时遇到了与Chrome驱动程序相关的错误.错误消息是" 无法发现打开的页面. "Selenium测试一直运行到昨晚.问题似乎是在前一天重新启动服务器后开始的.我无法在本地方框上重现此错误.从服务器上的命令行运行Selenium测试会打开Chrome浏览器,但会导致相同的错误.有任何想法吗？

失败的行:

chromeDriver = new OpenQA.Selenium.Chrome.ChromeDriver(externalDriverPath);

错误消息和堆栈跟踪:

在OpenQA.Selenium.Remium.RemoteWebDriver.Execute(String driverCommandToExecute,Dictionary)的OpenQA.Selenium.Remote.RemoteWebDriver.UnpackAndThrowOnError(响应errorResponse)中无法发现打开的页面(驱动程序信息:chromedriver = 2.1,platform = Windows NT 6.1 SP1 x86_64)在OpenQA.Selenium.Chlenium.Chrome.ChromeDriver..ctor(String chromeDriverDirectory)的OpenQA.Selenium.Remote.RemoteWebDriver.StartSession(ICapabilities desiredCapabilities)上的OpenQA.Selenium.Remote.Remote.RemoteWebDriver..ctor(ICommandExecutor commandExecutor,ICapabilities desiredCapabilities)的`2参数) ,ChromeOptions选项)在SeleniumTests.BaseTest.SetupBrowsers()的OpenQA.Selenium.Chrome.ChromeDriver..ctor(String chromeDriverDirectory)

创建ChromeDriver实例时,会出现一个控制台窗口.带错误的服务器似乎引用了未实现的内容.

具有错误的服务器的ChomeDriver输出:

在端口2984上启动ChromeDriver(v2.1)[4700:4292:0108/111503:错误:gpu_info_collector_win.cc(102)]无法检索va盖WinSAT评估.[4700:4292:0108/111503:错误:chrome_views_delegate.cc(176)]未实现[4700:4292:0108/111503:错误:desktop_root_window_host_win.cc(746)] NOT IMPLEMENT ED [0108/111504:错误:gl_surface_egl. cc(132)] eglInitialize失败,错误UNKNO WN [0108/111504:ERROR:gl_surface_win.cc(97)] GLSurfaceEGL :: InitializeOneOff失败.

从我的电脑ChomeDriver输出工作正常:

我最近将我的chrome版本升级到60并将chromedriver升级到版本2.31.发布当我尝试最大化浏览器窗口时,我已经开始获得以下异常.

    driver.driver.manage().window().maximize()

org.openqa.selenium.WebDriverException:未知错误:无法将窗口状态更改为最大化,当前状态正常(会话信息:chrome = 60.0.3112.78)(驱动程序信息:chromedriver = 2.31.488763(092de99f48a300323ecf8c2a4e2e7cab51de5ba8),platform = Linux 4.2 .0-27-generic x86_64)(警告:服务器未提供任何堆栈跟踪信息)命令持续时间或超时:108毫秒构建信息:版本:'2.53.1',修订版:'a36b8b1cd5757287168e54b817830adce9b0158d',时间:'2016-06 -30 19:26:09'系统信息:主机:'bb-blr-prod-stage-stg1-01',ip:'10 .3.211.2',os.name:'Linux',os.arch:'amd64' ,os.version:'4.2.0-27-generic',java.version:'1.7.0_80'会话ID:c7de7149dd490cc7760d2f4fc49f0325驱动信息:org.openqa.selenium.chrome.ChromeDriver Capabilities [{platform = LINUX,acceptSslCerts = true ,javascriptEnabled = true,browserName = chrome,chrome = {userDataDir =/tmp/.org.chromium.Chromium.WABPhO,chromedriverVersion = 2.31.488763(092de99f48a300323ecf8c2a4e2e7cab51de5ba8)},networkCo nnectionEnabled = false,unexpectedAlertBehaviour =,rotate = false,setWindowRect = true,locationContextEnabled = true,mobileEmulationEnabled = false,pageLoadStrategy = normal,version = 60.0.3112.78,takesHeapSnapshot = true,cssSelectorsEnabled = true,databaseEnabled = false,handlesAlerts = true,browserConnectionEnabled = false,webStorageEnabled = true,nativeEvents = true,hasTouchScreen = false,applicationCacheEnabled = false,takesScreenshot = true}]

我在Geb上使用ChromeDriver在无头模式下运行我的测试.

• Chrome版本 - 60.0.3112.78
• chromedriver版本 - 2.31.488763
• 操作系统 - Ubuntu 14.04.4 LTS …

当我尝试在3台计算机中的2台上运行代码时出现此错误:

[0502/155335.565:ERROR:gpu_process_transport_factory.cc(1007)] Lost UI shared context.

这是代码:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
import os

chrome_options = Options()
chrome_options.add_argument("--headless")
chrome_options.add_argument("--disable-gpu")
chrome_options.add_argument("--window-size=1920x1080")

chrome_driver = os.getcwd() + "\\chromedriver.exe"
print "chrome driver:" + chrome_driver

driver = webdriver.Chrome(chrome_options=chrome_options, 
executable_path=chrome_driver)

driver.get("http://www.google.com")

luck_button = driver.find_element_by_css_selector("[name=btnI")
luck_button.click()

driver.get_screenshot_as_file("capture.png")

现在我已经检查了所有系统,它们运行的​​是Windows 10 64位,谷歌浏览器64位版本:66.0.3359.139,python 2.7 32位,chromedriver.exe 32位,pycharm 2018.1.1

有趣的是,如果我在没有无头选项的情况下运行它,那么一切正常.弹出浏览器,I'm feeling lucky按下按钮,然后拍摄屏幕截图.只有当我添加无头位时才会发生此错误.

我不确定在其他系统运行相同软件的情况下,1系统可能有什么不同.

我是硒的新手，只是想学习。尝试通过 ChromeDriver 打开 Chrome 浏览器时，出现以下错误：

尝试了很多谷歌搜索，但没有任何帮助。下面是我的代码： …

如果我们创建：

ChromeDriver driver=new ChromeDriver();

chrome 驱动程序方法将被执行。

如果我们创建：

WebDriver driver=new ChromeDriver();

再次ChromeDriver执行方法[根据方法覆盖]。

那为什么我们只在执行时写后一个呢？
