### Question:
TaskunImpl implements Taskun { @Override public boolean isRunning() { return !(executorService == null || executorService.isTerminated()); }  void initialize(TaskunConfig config); void initialize(TaskunInjector taskunInjector); @Override void start(); @Override void scheduleCronExecute(Runnable runnable, RawCrontabLine crontabLine); @Override void scheduleIntervalExecute(Runnable runnable, Calendar initialScheduledDate, long interval, TimeUnit timeUnit); @Override void scheduleOnetime(Runnable runnable, Calendar scheduledDate); @Override void shutdown(); @Override void replaceCrontabFile(String crontabFilepath); @Override boolean isRunning(); @Override List<RawCrontabLine> getCurrentRawCrontabLines(); @Override long getLastCronInvocationTimeMillis();  }### Answer:
@Test public void isRunning_A$() throws Exception { assertTrue(taskun.isRunning()); }
