### Question:
ControlSignalSentInfo { public void setTimeMillis(long timeMillis) { this.timeMillis = timeMillis; } ControlSignalSentInfo(int count, long timeMillis); long getTimeMillis(); void setTimeMillis(long timeMillis); int getSendTryCount(); void setSendTryCount(int sendTryCount);  }### Answer:
@Test public void testSetTimeMillis() { timeMillis = timeMillis + 100; controlSignalSentInfo.setTimeMillis(timeMillis); assertEquals(timeMillis, controlSignalSentInfo.getTimeMillis()); }
