Answer 1

您必须设置网络驱动程序。 试试下面：

System.setProperty("webdriver.gecko.driver", "Path to .exe");

WebDriver driver = new FirefoxDriver();

driver.get("http://seleniumhq.com");

Answer 2

您必须在系统属性中设置 geckodriver 文件：

System.setProperty("webdriver.gecko.driver","path to geckodriver.exe");

解压文件geckodriver-v0.16.1-win64.zip并设置geckodriver.exe的路径。

Answer 3

您没有正确输入 geckdriver 的路径。 提取为 geckodriver 下载的文件，并在提取的文件夹中设置路径为“geckodriver.exe”。 参考这个。

System.setProperty("webdriver.gecko.driver","G:\\Selenium\\Firefox driver\\geckodriver.exe");//set path as per location of your geckodriver
