### Question:
FunctionColumnParametersHeaderMetaData extends EditablePopupHeaderMetaData<HasParametersControl, ParametersPopoverView.Presenter> { @Override public String getTitle() { return getFormalParametersTitle(); } FunctionColumnParametersHeaderMetaData(final Supplier<Optional<FunctionDefinition>> functionSupplier,
                                                  final TranslationService translationService,
                                                  final CellEditorControlsView.Presenter cellEditorControls,
                                                  final ParametersPopoverView.Presenter editor,
                                                  final FunctionGrid gridWidget); @Override String getColumnGroup(); @Override String getTitle(); @Override Group render(final GridHeaderColumnRenderContext context,
                        final double blockWidth,
                        final double blockHeight); @Override Optional<String> getPlaceHolder();  }### Answer:
@Test public void testGetTitle() { KindUtilities.setKind(this.function, FunctionDefinition.Kind.FEEL); setupFormalParameters("p0", "p1"); assertEquals("(p0, p1)", header.getTitle()); }
