Answer 1

你需要下载chrome和IE的二进制文件，然后你还需要在代码中传递二进制文件的路径。

根据您的配置从下面的链接下载chrome二进制文件：-

http://chromedriver.storage.googleapis.com/index.html?path=2.21/

有关Internet Explorer，请从以下链接下载：-

http://www.seleniumhq.org/download/#mainContent（Internet Explorer驱动程序服务器）

现在使用setProperty设置二进制文件的路径，然后将其传递给chromedriver对象，如下所示：-

System.setProperty("webdriver.chrome.driver", "/path/to/chromedriver");
WebDriver driver = new ChromeDriver();
