How to use the @aurelia/i18n.TranslationBindBindingRenderer function in @aurelia/i18n

it('instantiated with instruction type', function () {
    const container = setup();
    const sut: IInstructionRenderer = new TranslationBindBindingRenderer(container.get(IExpressionParser), {} as unknown as IObserverLocator);
    assert.equal(sut.instructionType, TranslationBindInstructionType);
  });

it('#render adds expr to the existing TranslationBinding for the target element', function () {
    const container = setup();
    const sut: IInstructionRenderer = new TranslationBindBindingRenderer(container.get(IExpressionParser), {} as unknown as IObserverLocator);
    const expressionParser = container.get(IExpressionParser);
    const targetElement = DOM.createElement('span');
    const binding = new TranslationBinding(targetElement, {} as unknown as IObserverLocator, container);
    const renderable = ({ bindings: [binding] } as unknown as IController);

    const from = expressionParser.parse('simple.key', BindingType.BindCommand);
    const callBindingInstruction: ICallBindingInstruction = { from, to: '.bind' } as unknown as ICallBindingInstruction;
    sut.render(
      LifecycleFlags.none,
      DOM,
      container as unknown as IRenderContext,
      renderable,
      targetElement,
      callBindingInstruction);

    assert.equal(binding.expr, from);
