我在selenium（java）范围报告中得到一个空饼图 . 它看起来全黑了

我正在为我的selenium测试脚本生成一个范围报告 . 它不是一个maven项目 . 这是一个简单的java项目 . 使用的extentReports jar的版本是2.41.2 . 我能够生成一个HTML报告，但问题是PASS / FAIL结果没有反映在我的范围报告中 . 我在报告中得到了一张全黑的饼图 . 请参考屏幕截图 . Please refer the picture of my extent report.

下面是我的代码块：GenerateExtentReports.java（此类包含生成范围报告的方法）：

package SeleniumReports;

import java.io.File;
import java.lang.reflect.Method;
import java.text.SimpleDateFormat;
import java.util.Calendar;

import org.testng.Assert;
import org.testng.ITestResult;

import org.testng.annotations.BeforeTest;
import com.relevantcodes.extentreports.ExtentReports;
import com.relevantcodes.extentreports.ExtentTest;
import com.relevantcodes.extentreports.LogStatus;

public class GenerateExtentReports {
ExtentReports extent;
ExtentTest test;
ITestResult res;

@BeforeTest
public void reportSetup(){
    System.out.println("BeforTest_reportSetup");
    Calendar mycalendar = Calendar.getInstance();
    SimpleDateFormat formatter=new SimpleDateFormat("dd/mm/yyyy_hhmmss");
    String timestamp=formatter.format(mycalendar.getTime());

    extent=new ExtentReports(System.getProperty("user.dir")+"/TestOutput/My First Report"+timestamp+".html",true);
    extent.addSystemInfo("Host Name", "Rashmi").addSystemInfo("Environment", "QA").addSystemInfo("User Name", "Rashmi Sharma");

    extent.addSystemInfo("Host Name", "Rashmi").addSystemInfo("Environment", "QA").addSystemInfo("User Name", "Rashmi Sharma");
    extent.loadConfig(new File(System.getProperty("user.dir")+"\\extent-config.xml"));
    test=extent.startTest("loginUsingExcelData");
    System.out.println(extent.startTest("loginUsingExcelData").getRunStatus().toString());
}

@AfterMethod
public void getResults(ITestResult res) {
    System.out.println("AfterMethod_getResults");
    // TODO Auto-generated method stub
    if(res.getStatus()==ITestResult.SUCCESS){
        //test.log(LogStatus.PASS, res.getThrowable());
}
    else if(res.getStatus()==ITestResult.FAILURE){
        test.log(LogStatus.FAIL, res.getThrowable());
    }
    else if(res.getStatus()==ITestResult.SKIP){
        test.log(LogStatus.SKIP, res.getThrowable());
    }
    else if(res.getStatus()==ITestResult.STARTED){
        test.log(LogStatus.INFO, "Test started");
    }
    System.out.println("TestLogs conditions end here");
    extent.flush();
    extent.endTest(test);
    }}

有人可以帮忙吗？我一周以来都在苦苦挣扎 .
