在 Firefox 中进行 运行 测试时抛出 SessionNotCreatedException
Throws SessionNotCreatedException While running test in Firefox
我正在使用以下版本：
Selenium: 3.6.0
Mozilla: 56.0
Gecko Driver: V 0.19.0
当我 运行 testng.xml 为 mozilla firefox 文件时，它抛出这个异常：
Log:

代码：
if(browser.equalsIgnoreCase("firefox")) {
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);
capabilities.setCapability("platform", Platform.ANY);
capabilities.setCapability("binary", "C:\Program Files (x86)\Mozilla Firefox\firefox.exe");
driver=new FirefoxDriver(capabilities);
}
我认为您在初始化 FirefoxDriver() 之前没有更新 gecko 驱动程序的路径，所以
- 1st: 您需要将 geckodriver 下载到 运行 Firefox。 Download Link for Gecko Driver
- 2nd: 您可能需要在启动驱动程序之前设置 geckodriver 的路径。
因此您的代码应如下所示。
System.setProperty("webdriver.gecko.driver", "c:/path_to_driver/geckodriver.exe");
driver = new FirefoxDriver();
更新到最新的浏览器版本来解决这个问题。如果长时间坚持使用特定的浏览器版本，geckodriver 和 selenium 框架将变得不兼容。更新您的 firefox 版本，错误可能
