### Question:
PdfVersionCombo extends ComboBox<PdfVersionComboItem> implements ModuleOwned, ResettableView { @Override public void resetView() { versionsFilter.reset(); versionsFilter.addFilter(PdfVersion.VERSION_1_2); } PdfVersionCombo(String ownerModule); @EventListener void onAddPdfVersionConstraint(final AddPdfVersionConstraintEvent event); @EventListener void onRemovePdfVersionConstraint(final RemovePdfVersionConstraintEvent event); @EventListener void onChangedSelectedPdfVersion(final ChangedSelectedPdfVersionEvent event); @Override @EventStation String getOwnerModule(); @Override void resetView(); void enableSameAsSourceItem();  }### Answer:
@Test public void reset() { eventStudio().broadcast(new AddPdfVersionConstraintEvent(PdfVersion.VERSION_1_5), MODULE); assertEquals(PdfVersion.VERSION_1_5, victim.getSelectionModel().getSelectedItem().getVersion()); assertEquals(3, victim.getItems().size()); victim.resetView(); assertEquals(5, victim.getItems().size()); }
