指导我解决这个问题.

解决方案

您使用的是 Selenium WebDriver 的最新版本，即 Selenium 3.x，此版本的 webdriver 不支持'不支持直接启动 Firefox.您必须为 webdriver.gecko.driver 设置 SystemProperty.

替换代码:-

WebDriver 驱动程序；驱动程序 = 新的 FirefoxDriver();

使用此代码:-

WebDriver 驱动程序；System.setProperty("webdriver.gecko.driver", "<你的 WebDriver 的路径>");驱动程序 = 新的 FirefoxDriver();

您可以在此处获取有关最新更改的信息

解决方案

You are using latest version of Selenium WebDriver i.e. Selenium 3.x, this version of webdriver doesn't support direct firefox launch. You have to set the SystemProperty for webdriver.gecko.driver.

Replace the Code:-

WebDriver driver;
driver =new FirefoxDriver();

With This code:-

WebDriver driver;
System.setProperty("webdriver.gecko.driver", "<Path to your WebDriver>");
driver =new FirefoxDriver();
