Automated tests 扩展测试报告V3（junit4）-通过将1个类下的测试用例附加到唯一报告中进行故障排除

我在将测试附加到测试报告中时遇到问题。我只想做最基本的步骤，所以我写了4TC。当我运行它们并打开报告时，每次它们在报告中重复时。 我使用的是数据块报告版本3和Junit4，我遵循了他们网站上的文档。 有人能帮我解决这个问题，并了解如何为一个类下的所有tc创建正确的报告吗？对于附加测试用例，我使用命令

htmlReporter.setAppendExisting（true）。
这是我的代码：

    public class ExtentReport3 {


@Test
    public void OpenaAccount() throws Exception{
    ExtentHtmlReporter htmlReporter = new ExtentHtmlReporter("./src/TestExtent3.html");
    htmlReporter.setAppendExisting(true);


    // create ExtentReports and attach reporter(s)
    ExtentReports extent = new ExtentReports();
    extent.attachReporter(htmlReporter);

    // creates a toggle for the given test, adds all log events under it
    ExtentTest test = extent.createTest("4.Open account test", "Sample description");

    // log(Status, details)
    test.log(Status.INFO, "Step 1");
    test.log(Status.INFO, "Step 2");

    extent.flush();
}
@Test
public void LoginForm () throws Exception{
    ExtentHtmlReporter htmlReporter = new ExtentHtmlReporter("./src/TestExtent3.html");
    htmlReporter.setAppendExisting(true);

    // create ExtentReports and attach reporter(s)
    ExtentReports extent = new ExtentReports();
    extent.attachReporter(htmlReporter);

    // creates a toggle for the given test, adds all log events under it
    ExtentTest test1 = extent.createTest("3.Login form", "Sample description");

    // log(Status, details)
    test1.log(Status.INFO, "Step 1");
    test1.log(Status.INFO, "Step 2");

    extent.flush();

}
@Test
public void CheckOutForm() throws Exception{

    ExtentHtmlReporter htmlReporter = new ExtentHtmlReporter("./src/TestExtent3.html");
    htmlReporter.setAppendExisting(true);

    // create ExtentReports and attach reporter(s)
    ExtentReports extent = new ExtentReports();
    extent.attachReporter(htmlReporter);

    // creates a toggle for the given test, adds all log events under it
    ExtentTest test2 = extent.createTest("1.Checkout form", "Sample description");

    // log(Status, details)
    test2.log(Status.INFO, "Step 1");
    test2.log(Status.INFO, "Step 2");

    extent.flush();
}
@Test
    public void CancelOredr() throws Exception{
    ExtentHtmlReporter htmlReporter = new ExtentHtmlReporter("./src/TestExtent3.html");
    htmlReporter.setAppendExisting(true);

    // create ExtentReports and attach reporter(s)
    ExtentReports extent = new ExtentReports();
    extent.attachReporter(htmlReporter);

    // creates a toggle for the given test, adds all log events under it
    ExtentTest test3 = extent.createTest("2.Cancel order", "Sample description");

    // log(Status, details)
    test3.log(Status.INFO, "Step 1");
    test3.log(Status.INFO, "Step 2");

    extent.flush();

}
