CountDownTimer implements Timer { @Override public boolean isRunning() { return !fired; } CountDownTimer(int time);  CountDownTimer(int time, boolean started); boolean update(int delta); void reset(); @Override String toString(); int getTimeLeft(); @Override boolean isRunning();  }### Answer:
@Test public void shouldStartNotStarted() { CountDownTimer countDownTimer = new CountDownTimer(1000); assertFalse(countDownTimer.isRunning()); }
@Test public void shouldStartStarted() { boolean started = true; CountDownTimer countDownTimer = new CountDownTimer(1000, started); assertTrue(countDownTimer.isRunning()); }
