Question

当我们使用监听器运行XML文件时，它的抛出错误。不使用监听器就可以正常工作。

Codeng.XML下面的代码

  <?xml version="1.0" encoding="UTF-8"?>

 <suite name="Suite One" parallel="none" >

   <listeners>

    <listener class-name="utility.ScreenshotUtility"></listener>    
 

    </listeners>
    <test name="Test One" preserve-order="true"> 

    <classes>


    <class name="stramobiedemo.Nativestarterbackedsingle" />

    </classes>

    </test>


    <test name="Test two" preserve-order="true"> 

    <classes>



    <class name="stramobiedemo.Backedemailsingle" />


    </classes>

    </test>
 
     

    </suit>

我在这里看不到与您listeners相关的任何错误。因为错误本身是不言自明的。

org.openqa.selenium.NoSuchSessionException：会话ID为空。 在调用quit（）后使用WebDriver？

它说，你在退出后使用WebDriver instance。检查您是否已正确实施了注释。好像你的一个测试方法是在退出后使用驱动程序实例。

selenium webdriver：当ruuning testng.xml文件时我收到错误会话ID为空。调用quit（）后使用WebDriver？
