### Question:
FormEditorPresenter extends KieEditor<FormModelerContent> { protected void removeAllDraggableGroupComponent(Collection<FieldDefinition> fields) { String groupId = translationService.getTranslation(FormEditorConstants.FormEditorPresenterModelFields); Iterator<FieldDefinition> it = fields.iterator(); while (it.hasNext()) { FieldDefinition field = it.next(); if (layoutDragComponentPalette.hasDraggableComponent(groupId, field.getId())) { layoutDragComponentPalette.removeDraggableComponent(groupId, field.getId()); } } } @Inject  FormEditorPresenter(FormEditorView view,

@Test public void testRemoveAllDraggableGroupComponent() { loadContent(); addAllFields(); when(layoutDragComponentPaletteMock.hasDraggableComponent(anyString(), anyString())).thenReturn(true); List<FieldDefinition> fieldList = presenter.getFormDefinition().getFields(); presenter.removeAllDraggableGroupComponent(fieldList); verify(translationService, times(1)).getTranslation(FormEditorConstants.FormEditorPresenterModelFields); verify(layoutDragComponentPaletteMock, times(fieldList.size())).removeDraggableComponent(anyString(), anyString()); }
