### Question:
CronInvocation implements Runnable { public void initialize(TaskunInjector taskunInjector, ScheduledExecutorService executorService) { initialize(taskunInjector, executorService, DEFAULT_CRONTAB_FILENAME); }  @Override void run(); void initialize(TaskunInjector taskunInjector, ScheduledExecutorService executorService); void initialize(TaskunInjector taskunInjector, ScheduledExecutorService executorService, String crontabFilepath); void addCrontabLine(RawCrontabLine line); List<RawCrontabLine> getCurrentRawCrontabLines(); long getPreviousCheckedTimeMillis();  }### Answer:
@Test public void initialize_A$TaskunInjector$ScheduledExecutorService() throws Exception { TaskunInjector taskunInjector = new SampleTaskunInjector(); ScheduledExecutorService executorService = null; crond.initialize(taskunInjector, executorService); }
@Test public void initialize_A$TaskunInjector$ScheduledExecutorService$String() throws Exception { TaskunInjector taskunInjector = new SampleTaskunInjector(); ScheduledExecutorService executorService = Mockito.mock(ScheduledExecutorService.class); String crontabFilepath = "sdfsafa"; crond.initialize(taskunInjector, executorService, crontabFilepath); }
