如何为多个测试类创建多个范围报告

Question

I have different Test classes in different Testfiles, I want to create different Extent reports for each test files, right now only one report is generated which is overridden. I am using AventStack.ExtentReports.

这是扩展管理器类，其中包含路径和其他特定凭证
    公共静态ExtentHtmlReporter htmlReporter;             公共静态ExtentReports范围；

        public ExtentManager()
        {

        }
        public static ExtentReports GetInstance()
        {
            if (extent == null)
            {

                string reportpath = "\\Reports\\Report.html";

                htmlReporter = new ExtentHtmlReporter(reportpath);
                htmlReporter.Configuration().Theme = Theme.Dark;

                extent = new ExtentReports();
                extent.AttachReporter(htmlReporter);

                extent.AddSystemInfo("Host Name", "ABC");
                extent.AddSystemInfo("Environment", "Test QA");
                extent.AddSystemInfo("Username", "XYZ");

                htmlReporter.LoadConfig("extent-config.xml"); //Get the config.xml file 
            }
            return extent;
        }
public testclass1
{
     ExtentReports rep;
     ExtentTest test;
     public testclass()
     {
        rep = ExtentManager.GetInstance();
      }
   public void TestMethod1()
          {
            test = rep.CreateTest("LoginPage");
            test.Log(Status.Info, "Starting test");
            //My Login method to login in the app
            rep.flush();
           }
 }

public testclass2
{
    ExtentReports rep;
     ExtentTest test;
     public testclass()
     {
        rep = ExtentManager.GetInstance();
      }
   public void TestMethod2()
          {
            test = rep.CreateTest("userblock");
            test.Log(Status.Info, "Starting test");
            //My userblockmethod
            rep.flush();
           }
}

//创建一个覆盖它的报告，并给出最后执行的测试类的报告 结果-
testclass1Report.html testclass2Report.html
