“无法查找地址信息”错误在Mac OS上使用Gecko驱动程序执行selenium测试时显示

Question

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

这是我用来初始化Web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，似乎Gecko驱动程序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

显然，JDK和OSX存在主机名无法识别localhost的问题。

解决方案是将localhost添加到/ etc / hosts

Answer 2

您需要将功能传递给驱动程序：

WebDriver driver = new FirefoxDriver(capabilities);
