java - 无法在 selenium webdriver 上启动新 session

标签 java selenium firefox port gecko

我正在尝试使用 selenium java 代码打开 Firefox 浏览器。

System.setProperty("webdriver.gecko.driver", "  System.setProperty("webdriver.gecko.driver", "C:/Program Files/Mozilla Firefox/geckodriver-v0.8.0-win32/geckodriver.exe");

WebDriver driver = new FirefoxDriver();
System.setProperty("webdriver.firefox.port","4444");

Selenium 服务器已启动并正在运行。我尝试使用命令提示符更改selenium服务器端口并在代码中设置端口，但它们都不起作用。

> Exception in thread "main" org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.

在错误消息“连接到本地主机:6544”中，它每次都尝试连接到不同的本地主机。谁能看出问题出在哪里吗？

我使用的版本是:

  • 火狐浏览器48.0
  • Selenium 3.0.0 beta 2
  • Windows 7 32 位
  • geckodriver-v0.8.0-win32

此外，我的 geckodriver 可执行文件未运行，它表示 VCRUNTIME140.dill 丢失，我应该重新安装以解决问题。但我重新安装后，又发生了同样的事情。

更新

感谢@Saurabh的建议，我将我的selenium降级到2.53.1。浏览器现在正在打开，但没有显示任何内容。我又遇到了一个错误

最佳答案

您需要将具有 marionette 功能的 DesiredCapability 传递给 true 到 FirefoxDriver 中，如下所示:-

System.setProperty("webdriver.gecko.driver", "C:/Program Files/Mozilla Firefox/geckodriver-v0.8.0-win32/geckodriver.exe");

//Now you can Initialize marionette driver to launch firefox
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);
WebDriver driver = new FirefoxDriver(capabilities);

已编辑:如果不幸的是上述方法不起作用，我建议您将您的 Firefox 降级到 45 或更低并使用 FirefoxDriver，如下所示:-

WebDriver driver = new FirefoxDriver();
