### Question:
CronInvocation implements Runnable { public long getPreviousCheckedTimeMillis() { return previousCheckedTimeMillis; }  @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 getPreviousCheckedTimeMillis_A$() throws Exception { long actual = crond.getPreviousCheckedTimeMillis(); long expected = 0L; assertEquals(expected, actual); }
