### Question:
TimelineFragment extends ControllerPresenterFragment<TimelineView> implements TimelineAdapter.OnItemClickListener,
        BaseFragmentPagerAdapter.Controller { @Override public void onSegmentItemClicked(final int position, final View view, @NonNull final TimelineEvent event) { boolean animateShow = true; if (this.infoOverlay != null) { animateShow = false; this.infoOverlay.dismiss(false); } if (view.getY() < this.toolTipHeight) { final int dy = this.toolTipHeight * 2 - (int) view.getY(); this.presenterView.scrollForSpace(this, event, view, position, -dy); return; } this.infoOverlay = new TimelineInfoOverlay(getActivity(), getAnimatorContext()); this.infoOverlay.setOnDismiss(sender -> { if (sender == this.infoOverlay) { this.infoOverlay = null; } }); this.infoOverlay.bindEvent(event); this.infoOverlay.show(view, this.presenterView, Views.getActivityScreenSize(getActivity(), false), animateShow); Analytics.trackEvent(Analytics.Timeline.EVENT_TAP, null); Analytics.trackEvent(Analytics.Timeline.EVENT_LONG_PRESS_EVENT, null); }  static TimelineFragment newInstance(@NonNull final LocalDate date,
                                               @Nullable final Timeline cachedTimeline); @Override void setVisibleToUser(final boolean isVisible); @Override void initializePresenterView(); @Override void onCreate(final Bundle savedInstanceState); @Override void onViewCreated(final View view, final Bundle savedInstanceState); @Override void onTrimMemory(final int level); @Override void onPause(); @Override void onDestroyView(); @Override void onDetach(); @Override void onActivityResult(final int requestCode, final int resultCode, final Intent data); @Override void onRequestPermissionsResult(final int requestCode, @NonNull final String[] permissions, @NonNull final int[] grantResults); void showTimelineNavigator(@NonNull final LocalDate date,
                                      @Nullable final Timeline timeline); void share(); void showBreakdown(@NonNull final View sender); void dismissVisibleOverlaysAndDialogs(); @SuppressWarnings("ConstantConditions") @NonNull LocalDate getDate(); @Nullable Timeline getCachedTimeline(); void onSwipeBetweenDatesStarted(); void scrollToTop(); void update(); boolean isAtLeastThreeDaysOld(); void bindTimeline(@NonNull final Timeline timeline); void timelineUnavailable(final Throwable e); @Override void onSegmentItemClicked(final int position, final View view, @NonNull final TimelineEvent event); @Override void onEventItemClicked(final int eventPosition, @NonNull final TimelineEvent event); static final int ZOOMED_OUT_TIMELINE_REQUEST; }### Answer:
@Test public void onSegmentItemClickedTest() { final View view = mock(View.class); when(view.getY()).thenReturn(0f); fragment.toolTipHeight = 1; final int scrollY = -2; fragment.infoOverlay = mock(TimelineInfoOverlay.class); spyOnPresenterView(); fragment.onSegmentItemClicked(0, mock(View.class), mock(TimelineEvent.class)); verify(fragment.infoOverlay).dismiss(eq(false)); verify(fragment.presenterView).scrollForSpace(any(), any(), any(), eq(0), eq(scrollY)); }
