### Question:
MapboxTelemetry implements FullQueueCallback, ServiceTaskCallback { public boolean enable() { if (TelemetryEnabler.isEventsEnabled(applicationContext)) { startTelemetry(); return true; } return false; } MapboxTelemetry(Context context, String accessToken, String userAgent);   MapboxTelemetry(Context context, String accessToken, String userAgent, EventsQueue queue,
                  TelemetryClient telemetryClient, Callback httpCallback, SchedulerFlusher schedulerFlusher,
                  Clock clock, TelemetryEnabler telemetryEnabler, ExecutorService executorService); @Override // Callback is dispatched on background thread void onFullQueue(List<Event> fullQueue); @Override void onTaskRemoved(); boolean push(Event event); boolean enable(); boolean disable(); boolean updateSessionIdRotationInterval(SessionInterval interval); void updateDebugLoggingEnabled(boolean isDebugLoggingEnabled); void updateUserAgent(String userAgent); boolean updateAccessToken(String accessToken); boolean addTelemetryListener(TelemetryListener listener); boolean removeTelemetryListener(TelemetryListener listener); boolean addAttachmentListener(AttachmentListener listener); boolean removeAttachmentListener(AttachmentListener listener); @SuppressWarnings("WeakerAccess") @Deprecated synchronized boolean setBaseUrl(String eventsHost); boolean isCnRegion(); synchronized void setCnRegion(boolean setCnRegion);  }### Answer:
@Test public void checksFlusherRegisteringWhenEnabled() throws Exception { Context mockedContext = mock(Context.class, RETURNS_DEEP_STUBS); SchedulerFlusher mockedSchedulerFlusher = mock(SchedulerFlusher.class); MapboxTelemetry theMapboxTelemetry = obtainMapboxTelemetryWith(mockedContext, mockedSchedulerFlusher); theMapboxTelemetry.enable(); verify(mockedSchedulerFlusher, times(1)).register(); }
@Test public void checksFlusherSchedulingWhenEnabled() throws Exception { Context mockedContext = mock(Context.class, RETURNS_DEEP_STUBS); SchedulerFlusher mockedSchedulerFlusher = mock(SchedulerFlusher.class); MapboxTelemetry theMapboxTelemetry = obtainMapboxTelemetryWith(mockedContext, mockedSchedulerFlusher); theMapboxTelemetry.enable(); verify(mockedSchedulerFlusher, times(1)).schedule(anyLong()); }
