### Question:
DMNEditBusinessKnowledgeModelToolboxAction implements ToolboxAction<AbstractCanvasHandler> { @Override public String getTitle(final AbstractCanvasHandler canvasHandler, final String uuid) { return translationService.getValue(CoreTranslationMessages.EDIT); } @Inject  DMNEditBusinessKnowledgeModelToolboxAction(final SessionManager sessionManager,
                                                      final ClientTranslationService translationService,
                                                      final Event<EditExpressionEvent> editExpressionEvent); @Override Glyph getGlyph(final AbstractCanvasHandler canvasHandler,
                          final String uuid); @Override String getTitle(final AbstractCanvasHandler canvasHandler,
                           final String uuid); @Override @SuppressWarnings("unchecked") ToolboxAction<AbstractCanvasHandler> onMouseClick(final AbstractCanvasHandler canvasHandler,
                                                             final String uuid,
                                                             final MouseClickEvent event);  }### Answer:
@Test public void testTitle() { tested.getTitle(canvasHandler, E_UUID); verify(translationService, times(1)).getValue(eq(CoreTranslationMessages.EDIT)); }
