问题描述
java.lang.classCastException 错误与 Listeners/ExtenReporterNG 类有关。我知道是这种情况，因为当我从 TestNG 中删除以下几行时，所有测试用例都会运行而不会出现此错误。
<listeners>
<listener class-name= "resources.ExtentReporterNG"/>
<listener class-name= "Academy.Listeners"/>
</listeners>
我已经用尽了所有方法来处理这样的问题。感谢您的建议。
解决方法
尝试类 ExtentReporterNG 实现 IReporter
,我的范围报告代码是：
package resources;
import com.aventstack.extentreports.ExtentReports;
import com.aventstack.extentreports.reporter.ExtentSparkReporter;
public class ExtentReporterNG {
static ExtentReports extent;
public static ExtentReports getReportObject()
{
String path =System.getProperty("user.dir")+"\\reports\\index.html";
ExtentSparkReporter reporter = new ExtentSparkReporter(path);
reporter.config().setReportName("Web Automation Results");
reporter.config().setDocumentTitle("Test Results");
extent =new ExtentReports();
extent.attachReporter(reporter);
extent.setSystemInfo("Tester","Adam");
return extent;
}
}
======================
我的 Listeners 类代码是：
package Academy;
import java.io.IOException;
import org.openqa.selenium.WebDriver;
import org.testng.ITestContext;
import org.testng.ITestListener;
import org.testng.ITestResult;
import com.aventstack.extentreports.ExtentReports;
import com.aventstack.extentreports.ExtentTest;
import com.aventstack.extentreports.Status;
import resources.ExtentReporterNG;
import resources.base;
public class Listeners extends base implements ITestListener {
ExtentTest test;
ExtentReports extent =ExtentReporterNG.getReportObject(); .
ThreadLocal<ExtentTest> extentTest= new ThreadLocal<ExtentTest>();
@Override
public void onTestStart(ITestResult result) { // for every testcase as the name implies. For reporting.
test= extent.createTest(result.getMethod().getMethodName());
extentTest.set(test);
//ITestListener.super.onTestStart(result);
}
@Override
public void onFinish(ITestContext context) {
extent.flush();
}
@Override
public void onTestSuccess(ITestResult result) {
extentTest.get().log(Status.PASS,"TEST PASSED");
}
@Override
public void onTestFailure(ITestResult result) {
extentTest.get().fail(result.getThrowable());
WebDriver driver=null;
String testMethodName= result.getMethod().getMethodName();
try {
driver =(WebDriver)result.getTestClass().getRealClass().getDeclaredField("driver").get(result.getInstance());
} catch(Exception e)
{
}
try {
extentTest.get().addScreenCaptureFromPath(getScreenShotPath(testMethodName,driver),result.getMethod().getMethodName());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
========================================
TestNG XML 文件的内容是：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name="Suite">
<listeners>
<listener class-name= "resources.ExtentReporterNG"/>

</listeners>
<test thread-count="5" name="Test">

</test> <!-- Test -->

我已经找到了问题的根本原因：
在 TesNT.XML 文件中，您应该：
<listeners>
<listener class-name= "academy.Listeners"/>
</listeners>
代替
<listeners>
<listener class-name= "resources.ExtentReporterNG"/>
<listener class-name= "Academy.Listeners"/>
</listeners>
原因是，ExtentReporterNG.java 已经集成在 Listeners.java 中
