### Question:
TimeService { public long getCurrentMillis() { return System.currentTimeMillis(); }  long getCurrentMillis();  }### Answer:
@Test public void assertGetCurrentMillis() throws Exception { Assert.assertTrue(timeService.getCurrentMillis() <= System.currentTimeMillis()); }
@Test public void assertGetCurrentMillis() { assertTrue(timeService.getCurrentMillis() <= System.currentTimeMillis()); }
@Test public void testGetCurrentMillis() throws Exception { assertTrue(timeService.getCurrentMillis() <= System.currentTimeMillis()); }
