鉴于此代码:
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
from selenium.webdriver.support.ui import Select
from selenium.webdriver.common.by import By
# import org.openqa.selenium.Keys
import datetime
import time
import unittest
cap = DesiredCapabilities().INTERNETEXPLORER
cap['ignoreProtectedModeSettings'] = True
cap['IntroduceInstabilityByIgnoringProtectedModeSettings'] = True
cap['nativeEvents'] = True
cap['ignoreZoomSetting'] = True
cap['requireWindowFocus'] = True
cap['INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS'] = True
browser = webdriver.Ie(capabilities=cap, executable_path=r'C:\IEDriverServer_x64_3.150.1\IEDriverServer.exe')
browser.get("https://www.google.ro/?safe=active&ssui=on")
search_form = browser.find_element_by_xpath('/html[1]/body[1]/div[1]/div[1]/div[3]/div[1]/button[1]')
search_form.click()
当我运行它时，每次尝试，在任何网站上都会返回此错误:
raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.TimeoutException: Message: Timed out waiting for page to load.
在不同的 PC 上运行相同的代码工作正常，在我的情况下，我希望测试因找不到元素而失败，因为指定的 xpath 是错误的。
进程“卡在”
browser.get("https://www.google.ro/?safe=active&ssui=on")
好像页面没有正确加载。
我使用的是python 3.8.0 IEDriverServer_x64_3.150.1 Selenium 驱动程序
最佳答案
此错误消息...
raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.TimeoutException: Message: Timed out waiting for page to load.
...暗示 IEDriverServer 可执行二进制文件无法启动/生成新的浏览上下文，即 Internet Explorer 浏览 session 。
根据 Required Configuration的Internet Explorer Driver :
保护模式
在 Windows Vista 或 Windows 7 上的 Internet Explorer 7 或更高版本上，您必须将每个区域的保护模式设置设置为相同的值。该值可以打开或关闭，只要每个区域都相同即可。要设置保护模式设置，您必须从“工具”菜单中选择“Internet 选项”，然后单击安全选项卡。对于每个区域，选项卡底部都会有一个标记为启用保护模式的复选框。
此外，@JimEvans 在他的文章 You're Doing It Wrong: IE Protected Mode and WebDriver 中明确提到:
Using the capability doesn't solve the underlying problem though. If a Protected Mode boundary is crossed, very unexpected behavior including hangs, element location not working, and clicks not being propagated, could result. To help warn people of this potential problem, the capability was given big scary-sounding names like
INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINSin Java andIntroduceInstabilityByIgnoringProtectedModeSettingsin .NET. We really thought that telling the user that using this setting would introduce potential badness in their code would discourage its use, but it turned out not to be so.
解决方案
要使用 Selenium 访问网址 https://www.google.ro/?safe=active&ssui=on驱动selenium-iedriver发起 internet-explorer 浏览上下文您可以使用以下最小代码块:
from selenium import webdriver
driver = webdriver.Ie(executable_path=r'C:\WebDrivers\IEDriverServer.exe')
driver.get('https://www.google.ro/?safe=active&ssui=on')
其他注意事项
确保执行以下步骤:
- 将 JDK 升级到当前级别 JDK 8u251 .
- 将Selenium升级到当前级别 Version 3.141.59 .
- 将 IEDriverServer 升级到最新版本 IEDriverServer v3.150.1级别。
Note: As per best practices as Selenium Client and InternetExplorerDriver are released in sync and you must try to use both the binaries from the same major release.
- 通过IDE清理您的项目工作区，并仅使用所需的依赖项重建项目。
- 执行您的
@Test。 - 始终在
tearDown(){}方法中调用driver.quit()来关闭和销毁 WebDriver 和 Web Client 优雅地实例化。
