### Question:
ChronoFragment extends RoboFragment implements ChronoInterface { @Override public void timeOut() { mNumberOfTimeouts++; if (mAlarmPlayer != null) { mAlarmPlayer.start(); } new Thread(new Runnable() { @Override public void run() { if (mTickPlayer != null) { mTickPlayer.start(); } } }).start(); getActivity().runOnUiThread(new Runnable() { @Override public void run() { mWholeLayout.setBackgroundResource(R.drawable.timeout_background_gradient); } }); }  @Override View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState); @Override void onStart(); @Override void onResume(); int getNumberOfParticipants(); @Override void setTime(int time); void pauseTickSound(); @Override void setDailyTimer(final String string); @Override void timeOut(); @Override void setCountDown(final String string); void resetBackground(); @Override void onStop(); int getNumberOfTimeouts(); String getPreparationTime(); static final String TOTAL_TIME; static final String TIMEOUTS; static final String WARMUP_TIME; static final String PREFS_NAME; static final String TIME_SLOT_LENGTH; }### Answer:
@Test public void whenResetCountDownThenUndoTimeout() { when(mockTickPlayer.isPlaying()).thenReturn(true); wholeLayout.performClick(); assertEquals("Participant:1", mParticipantTextView.getText().toString()); out.timeOut(); wholeLayout.performClick(); verify(mockTickPlayer).isPlaying(); verify(mockTickPlayer).pause(); assertFalse(0xFFFF0000 == Robolectric.shadowOf(wholeLayout).getBackgroundColor()); }
