Selenium 从Testng运行测试组时在Testlistener中获取java.lang.ClasscastException

我试图使用Testlistner类运行一个存储在TestVWLoginPage和Testng中的测试用例，当在testlistener中将驱动程序从基类存储到局部变量时，我遇到了classcast异常

我已经附加了Testlistenere类、错误代码和第行的受影响代码

在调试过程中，我意识到如果我不在testng文件ie中运行组，它可以正常工作

<groups>
     <run>
        <include name = "Guitest" />
     </run>
  </groups>
   <classes>
     <class name = "VWAutomationTest.TestVWLoginPage" />
  </classes>

}

我失败的代码-

@Override
public void onTestFailure(ITestResult iTestResult) {
    System.out.println("I am in onTestFailure method " +  getTestMethodName(iTestResult) + " failed");

    //Get driver from BaseTest and assign to local webdriver variable.
    Object testClass = iTestResult.getInstance();
    WebDriver webDriver = ((BaseClass) testClass).getDriver();


    //Take base64Screenshot screenshot.
    String base64Screenshot = "data:image/png;base64,"+((TakesScreenshot)webDriver).
            getScreenshotAs(OutputType.BASE64);

    //Extentreports log and screenshot operations for failed tests.
    ExtentTestManager.getTest().log(LogStatus.FAIL,"Test Failed",
            ExtentTestManager.getTest().addBase64ScreenShot(base64Screenshot));
}

例外情况呢-

请将您的ITestResult.class和BaseClass.class添加到您的问题中，如果您需要测试类，您可能需要编写testClass=ITestResult.getTestClass（）。以前工作正常，现在我已将基类转移到单独的包中，我也已将该包导入Testlistener中。
