Question

我正在尝试使用Testlistner类使用Testng运行存储在TestVWLoginPage中的测试用例，将驱动程序从基类存储到testlistener中的局部变量时，我遇到了类转换异常。

我已经附加了Testlistenere类，错误代码和受影响的代码行。

在调试时，我意识到，如果我不在testng文件中运行组，也可以正常工作。

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

添加上面的代码后，我收到了classcast异常随附的代码-

Testlistner类-

package Listeners;

import com.relevantcodes.extentreports.LogStatus;

import java.util.Set;

import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.testng.ITestContext;
import org.testng.ITestListener;
import org.testng.ITestNGMethod;
import org.testng.ITestResult;
import Utility.BaseClass;
import ExtentReports.ExtentManager;
import ExtentReports.ExtentTestManager;


public class TestListener implements ITestListener {

private static String getTestMethodName(ITestResult iTestResult) {
    return iTestResult.getMethod().getConstructorOrMethod().getName();
}


//Before starting all tests, below method runs.
@Override
public void onStart(ITestContext iTestContext) {
    System.out.println("I am in onStart method " + iTestContext.getName());
    //iTestContext.setAttribute("WebDriver", this.driver);
}

//After ending all tests, below method runs.
@Override
public void onFinish(ITestContext iTestContext) {
    System.out.println("I am in onFinish method " + iTestContext.getName());





    //Do tier down operations for extentreports reporting!
    ExtentTestManager.endTest();
    ExtentManager.getReporter().flush();

}

@Override
public void onTestStart(ITestResult iTestResult) {
    System.out.println("I am in onTestStart method " +  getTestMethodName(iTestResult) + " start");
    //Start operation for extentreports.
    ExtentTestManager.startTest(iTestResult.getMethod().getMethodName(),"");
}

@Override
public void onTestSuccess(ITestResult iTestResult) {
    System.out.println("I am in onTestSuccess method " +  getTestMethodName(iTestResult) + " succeed");
    //Extentreports log operation for passed tests.
    ExtentTestManager.getTest().log(LogStatus.PASS, "Test passed");
}

@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));
}

@Override
public void onTestSkipped(ITestResult iTestResult) {
    System.out.println("I am in onTestSkipped method "+  getTestMethodName(iTestResult) + " skipped");
    //Extentreports log operation for skipped tests.
    ExtentTestManager.getTest().log(LogStatus.SKIP, "Test Skipped");
}

@Override
public void onTestFailedButWithinSuccessPercentage(ITestResult iTestResult) {
    System.out.println("Test failed but it is in defined success ratio " + getTestMethodName(iTestResult));
}

}

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));
}

还有例外-

从Testng运行测试组时，在Testlistener中获取java.lang.ClasscastException
