是否可以定义一个包含字符串格式信息的接口？请看以下示例:

interface timeMarkers{
    markerTime: string[]        
};

一个例子是:

{
   markerTime: ["0:00","1:30", "1:48"]                   
}

我的问题:有没有办法定义类型markerTime,以便字符串值必须始终匹配此正则表达式,而不是简单地声明它string[]并从那里开始？

var reg = /[0-9]?[0-9]:[0-9][0-9]/;

我有一个测试用例。该项目正在使用@testing-library/react

it('renders content if loading is false', async () => {
    await waitFor(() => {
      render(<Loader loading={false}><span>foo</span></Loader>);
    });
    const loaderElementText = screen.getByText('Loading');
    expect(loaderElementText).not.toBeInTheDocument();
    const contentText = screen.getByText('foo');
    expect(contentText).toBeInTheDocument();
  });

它不允许我运行expect(loaderElementText).not.toBeInTheDocument();带有以下错误的行：

TestingLibraryElementError: Unable to find an element with the text: Loading. This could be because the text is broken up by multiple elements. In this case, you can provide a function for your text matcher to make your matcher more flexible.

反向测试用例按loading={true}预期工作。

我已经无计可施了。查询文档中的元素并期望找不到该元素的语法是什么？
