'failed to lookup address information' 在 Mac OS 上使用 Gecko 驱动程序执行 selenium 测试时显示错误

Question

我正在使用 Gecko 驱动程序在 Mac OS 中执行 Selenium 测试。我正在使用 Firefox 56。

这是我用来初始化网络驱动程序的代码。

System.setProperty("webdriver.gecko.driver", "/Users/<username>/Documents/Tools/geckodriver");
DesiredCapabilities capabilities=DesiredCapabilities.firefox();         
capabilities.setCapability("marionette", true);
WebDriver driver = new FirefoxDriver(capabilities);

现在，当我执行测试时，Gecko 驱动程序似乎已初始化，但显示下面提到的错误并且浏览器未初始化。

您的解决方案将不胜感激。

Answer 1

您需要将功能传递给驱动程序：

WebDriver driver = new FirefoxDriver(capabilities);

Answer 2

显然存在主机名无法识别本地主机的问题with the JDK and OSX。

解决方法是将localhost添加到/etc/hosts
