自动化测试结果- JUnit ->如何进行普通分组/格式化？

@RunWith(Suite.class)
@Suite.SuiteClasses({TestClass1.class, TestClass2.class})
public class TestSuite {
    // 空的测试套件类
}

import org.junit.runner.JUnitCore;
import org.junit.runner.Result;
import org.junit.runner.notification.Failure;
import org.junit.runner.notification.RunListener;
import org.junit.runner.notification.RunNotifier;
import org.junit.runner.Description;
import org.junit.runner.RunWith;
import org.junit.runners.Suite;
import org.junit.runners.Suite.SuiteClasses;

@RunWith(Suite.class)
@SuiteClasses({TestClass1.class, TestClass2.class})
public class TestSuite {
    public static void main(String[] args) {
        JUnitCore runner = new JUnitCore();
        runner.addListener(new RunListener() {
            @Override
            public void testRunStarted(Description description) throws Exception {
                System.out.println("Running " + description.getClassName() + "...");
            }
        });
        Result result = runner.run(TestSuite.class);
        for (Failure failure : result.getFailures()) {
            System.out.println(failure.toString());
        }
        System.out.println("Tests run: " + result.getRunCount() + ", Failures: " + result.getFailureCount());
    }
}
