java.lang.IllegalStateException : The path to the driver executable must be set by the webdriver. gecko.driver 系统属性与 Selenium GeckoDriver

Question

任何人都可以帮助解决这些错误或告诉我导致这些错误的原因吗？我添加了从 seleniumHQ.org 下载的文件中的所有 .JAR 文件，但我仍然收到这些错误:

Exception in thread "main" java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.gecko.driver system property; for more information, see https://github.com/mozilla/geckodriver.

Answer 1

要在 Mozila Firefox 52.0.2 中使用 Selenium 3.x，您需要:

1. 下载 latest gecko driver并将其保存在“C:\your_folder”中。
2. 将提及 gecko 驱动程序的系统属性及其在系统上的绝对路径设置为:

System.setProperty("webdriver.gecko.driver", "C:\\your_folder\\geckodriver.exe");

接下来将 Webdriver 初始化为:

WebDriver 驱动程序 = new FirefoxDriver();

最大化浏览器:

driver.manage().window().maximize();

打开网址:

driver.get("http:\\gmail.com");

请告诉我这是否对您有帮助。
