### Question:
SelectionCopy extends BaseKeyboardOperation { @Override public boolean perform(final GridWidget gridWidget, final boolean isShiftKeyDown, final boolean isControlKeyDown) { final GuidedDecisionTableView view = (GuidedDecisionTableView) gridWidget; final GuidedDecisionTableView.Presenter dtPresenter = view.getPresenter(); dtPresenter.onCopy(); return false; } SelectionCopy(final GridLayer gridLayer); @Override int getKeyCode(); @Override TriStateBoolean isControlKeyDown(); @Override boolean isExecutable(final GridWidget gridWidget); @Override boolean perform(final GridWidget gridWidget,
                           final boolean isShiftKeyDown,
                           final boolean isControlKeyDown);  }### Answer:
@Test public void checkPerformanceWithSelectedCell() { uiModel.selectCell(0, 1); handler.perform(gridWidget, true, true); verify(dtPresenter, times(1)).onCopy(); }
