Sonarqube doesn't accept my test but it works in my Eclipse

Question

I have the following code. It creates a digital clock for 10 seconds. And when i'm doing commit in git SonarQube says that all my tests were failed there. But it works on my PC :\\

public final class Clock implements Runnable {

    private static final org.slf4j.Logger LOGGER = LoggerFactory.getLogger(Clock.class);
    private static JFrame                 frame  = new JFrame();
    private final Font                    clockFont;
    private volatile boolean              flag   = true;


    /**
     * Clock constructor.
     */

    public Clock() {

        Clock.frame.setSize(1000, 250);
        Clock.frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        Clock.frame.setVisible(true);
        Clock.frame.setResizable(false);

        this.clockFont = new Font("Serif", Font.BOLD, 40);

        final Container contentArea = Clock.frame.getContentPane();
        final ClockPanel timeDisplay = new ClockPanel();

        contentArea.add(timeDisplay);
        Clock.frame.setContentPane(contentArea);

    }

Main method

    public static void main(final String[] args) {
        final Clock clock = new Clock();
        final Thread thread = new Thread(clock);
        thread.start();
        try {
            Thread.sleep(10000);
        } catch (final InterruptedException e) {
            Thread.currentThread().interrupt();
            Clock.LOGGER.info("Interrupted Exception was thrown", e);
        }

        clock.stopRunning();
        Clock.LOGGER.info("program was successfully executed");
    }

timeWashington method

    public static String timeWashington() {

        final Calendar now = Calendar.getInstance();
        now.setTimeZone(TimeZone.getTimeZone("GMT-8"));

        final String month = new SimpleDateFormat("M", Locale.ENGLISH).format(now.getTime());
        final int date = now.get(Calendar.DATE);
        final int hrs = now.get(Calendar.HOUR_OF_DAY);
        final int min = now.get(Calendar.MINUTE);
        final int sec = now.get(Calendar.SECOND);

        return date + ", " + month + ", " + hrs + ":" + min + ":" + sec + " - Washington";
    }

and continuation of the code

    @Override
    public void run() {

        while (this.flag) {
            Clock.frame.repaint();

            try {
                Thread.sleep(1000);

            } catch (final InterruptedException e) {
                Thread.currentThread().interrupt();
                Clock.LOGGER.info("Interrupted Exception was thrown", e);
            }

        }
        Clock.frame.setVisible(false);
        Clock.frame.dispose();

    }

    /**
     * stopRunning method.
     */
    public void stopRunning() {
        this.flag = false;
    }

    /**
     * The ClockPanel fills current panel
     */
    class ClockPanel extends JPanel {

        private static final long serialVersionUID = 1L;

        @Override
        public void paintComponent(final Graphics painter) {

            painter.setFont(Clock.this.clockFont);
            painter.setColor(Color.black);
            painter.drawString(Clock.timeWashington(), 40, 40);
        }
    }

}

And my Junit tests are as follows:

public class ClockTest {

    @Rule
    public final SystemOutRule log = new SystemOutRule().enableLog();

    @Test
    public void testMain() throws InterruptedException {
        final String[] args = null;
        Clock.main(args);
        Assert.assertEquals("it should be  equal", "program was successfully executed",
                this.log.getLog());
    }

    @Test
    public void testTimeWashington() {

        boolean result = false;
        final String time = Clock.timeWashington();
        if ((time != null) && !time.isEmpty()) {
            result = true;
        }

        Assert.assertTrue("This will succeed.", result);
    }
}

Please tell me how i can fix it.

Answer 1

the root problem seems to be that your test is looking for class 'Clock':

java.lang.NoClassDefFoundError: Could not initialize class by.iba.gomel.Clock

But your implementation is Clock1

This implies to me that where you are running your tests is out of date compared to your local machine.

(ie either the rename from Clock to Clock1 or the associated update to your test case have not made it to where your test is being run)
