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

it('#render instantiates TranslationBinding - simple string literal', function () {
    const container = setup();
    const sut: IInstructionRenderer = new TranslationBindingRenderer(container.get(IExpressionParser), {} as unknown as IObserverLocator);
    const expressionParser = container.get(IExpressionParser);
    const renderable = ({} as unknown as IController);

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

    assert.instanceOf(renderable.bindings[0], TranslationBinding);
  });

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