java - Sonarqube 不接受我的测试，但它在我的 Eclipse 中工作

Question

我有以下代码。它创建一个 10 秒的数字时钟。当我在 git 中进行提交时，SonarQube 说我所有的测试都失败了。但它可以在我的电脑上运行:\

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);

    }

主要方法

    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");
    }

时间华盛顿方法

    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";
    }

以及代码的延续

    @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);
        }
    }

}

我的 Junit 测试如下:

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);
    }
}

请告诉我如何修复它。

最后 1 次构建失败(不稳定 # 288)花了 2 毫秒。

Answer 1

根本问题似乎是您的测试正在寻找“Clock”类:

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

但是你的实现是Clock1

这对我来说意味着您运行测试的位置与本地计算机相比已经过时了。

(即从 Clock 重命名为 Clock1 或测试用例的相关更新尚未到达运行测试的位置)
