Selenium Webdriver - SessionNotCreatedError

Question

我收到此错误：

SessionNotCreatedError：会话未创建超时异常：从渲染器接收消息超时：600.000

我正在 Windows 8 Chrome 上运行量角器测试。发生的情况是 Chrome 选项卡将打开但不会加载 url，并且会打开 C:\Program Files(x86)\Google\Chrome\Application\chrome.exe 外壳窗口。然后什么也没有发生，测试超时。我收到超时错误是有道理的。 但我不知道为什么它一开始就没有加载网站。

当我关闭 chrome 选项卡时，我会收到以下消息：

SessionNotCreatedError: session not created exception from tab crashed`

我在 selenium 独立版和 chromedriver 上都是最新的。我唯一能想到的是 Chrome 最近更新到了 46.0.2490.71，但是我在相同版本的 Windows 7 上没有任何问题。

这里有什么问题？？

编辑：我正在使用"protractor": "^2.5.1" 和"jasmine": "^2.3.2"

Answer 1

我遇到了同样的错误，请参阅下面的解决方案。

昨天检查了代码，一切正常。今天早上开了一间套房，看到可可看到的确切行为。

Chrome/chromedriver 是最新的。 Protractor 是 v2.2（正在升级），Jasmine v2x。 Webdriver-manager 更新显示一切都很酷。 JDK 是最新的。我唯一还在追逐的是 Jasmine-reporters，我使用的是 v2x。

编辑： 我刚刚解决了：

• 从 msi 文件更新 node.js（位于此处：https://nodejs.org/en/）

• 运行 webmanager 更新（webdriver-manager update），它会拉取最新的 selenium jar 和 chomedriver.exe

• 然后我运行了一个今天早上失败的测试，它运行成功，没有错误。

Answer 2

下载 Chromedriver 2.19 是我需要做的。我使用的是 2.16，由于某种原因 webdriver-manager update --chromedriver 无法正常工作，并说我有最新版本。但显然不是。谢谢@jjj！！

Answer 3

从网站http://www.seleniumhq.org/download/下载chrome浏览器 并将其保存在 C:\Downloads\chromedriver_win32

使用下面的语法来启动和初始化 chrome 驱动 driverGC = new ChromeDriver(@"C:\Downloads\chromedriver_win32");

Answer 4

您可能需要升级chromedriver。在 Mac 上，这应该像 brew upgrade chromedriver 一样简单。否则，您可以download the latest version 并将其放在适合您特定设置的正确文件夹中。
