Print Test Result in JUnit

Currently I am making the test case repeat 2 times, so how do I print the results as 2 separate results.

I tried using the built-in function to create the text, however, it does now show either "Success" or "Failure".

Currently I have this code:

public class UnitTestRunner {
    static JUnitCore junitCore;
    static Class<?> testClasses;

    public static void main(String[] args) {
        System.out.println("Running Junit Test Suite.");
        Result result = JUnitCore.runClasses(TestSuite.class);
        for (Failure failure : result.getFailures()) {
            System.out.println(failure.toString());
        }
        System.out.println("Successful: " + result.wasSuccessful() +
            " ran " + result.getRunCount() + " tests");
    }
}

This code is working correctly, but I do not know how to implement this into JUnit.

Can someone please help to show, how to implement this code into JUnit test case.

This will be slightly long answer. For the customized output you have to add your RunListener You can use following sample implementation for the same.

public class UnitTestRunner {
    static JUnitCore junitCore;
    static Class<?> testClasses;

    public static void main(String[] args) {
        System.out.println("Running Junit Test Suite.");

junitCore = new JUnitCore();

junitCore.addListener(new CustomExecutionListener());

        Result result = junitCore.run(TestSuite.class);
        for (Failure failure : result.getFailures()) {
            System.out.println(failure.toString());
        }
        System.out.println("Successful: " + result.wasSuccessful() + " ran " + result.getRunCount() + " tests");
    }
}

And implementation for the RunListener is as follows

import org.junit.runner.Description;
import org.junit.runner.Result;
import org.junit.runner.notification.Failure;
import org.junit.runner.notification.RunListener;

public class CustomExecutionListener extends RunListener {

    public void testRunStarted(Description description) throws Exception {
        System.out.println("Number of tests to execute: " + description.testCount());
    }

    public void testRunFinished(Result result) throws Exception {
        System.out.println("Number of tests executed: " + result.getRunCount());
    }

    public void testStarted(Description description) throws Exception {
        System.out.println("Starting: " + description.getMethodName());
    }

    public void testFinished(Description description) throws Exception {
        System.out.println("Finished: " + description.getMethodName());
    }

    public void testFailure(Failure failure) throws Exception {
        System.out.println("Failed: " + failure.getDescription().getMethodName());
    }

    public void testAssumptionFailure(Failure failure) {
        System.out.println("Failed: " + failure.getDescription().getMethodName());
    }

    public void testIgnored(Description description) throws Exception {
        System.out.println("Ignored: " + description.getMethodName());
    }
}

And by overriding the methods in RunListener you can format you output.
