Wordpress 如何对使用wp.apiFetch的gutenberg类/组件方法进行单元测试

我试图在调用wp.apiFetch方法的类/组件上对一个方法进行单元测试，但当我运行测试时，它总是说

TypeError:apiFetch不是一个函数

下面的结构适用于其他测试用例，尽管它们不进行任何api调用

精简测试设置

global.wp = {};
// some other packages
Object.defineProperty(global.wp, 'apiFetch', { get: () => require('@wordpress/api-fetch') });

精简测试

const { apiFetch } = wp;
// some more constants from window

class NewAuthor extends Component {
  // constructor
  // method to test
  createAuthor = () => {
    const { someFunc, someErrorFunc } = this.props;
    const authorObject = {
      name,
    } = this.state;
    const createPath = '/wp/v2/users';

    apiFetch({
      path: createPath,
      data: authorObject,
      method: 'POST',
    })
      .then((user) => {
        console.log('success', user);
        someFunc();
      })
      .catch((error) => {
        console.log('error', error);
        someErrorFunc();
      });
  };
  // some more methods
  // render
}

export default NewAuthor;

浅层渲染组件

在组件实例上调用有问题的方法-此时，由于顶部提到的错误，测试出错

检查是否调用了该方法

const { apiFetch } = wp;
// some more constants from window

class NewAuthor extends Component {
  // constructor
  // method to test
  createAuthor = () => {
    const { someFunc, someErrorFunc } = this.props;
    const authorObject = {
      name,
    } = this.state;
    const createPath = '/wp/v2/users';

    apiFetch({
      path: createPath,
      data: authorObject,
      method: 'POST',
    })
      .then((user) => {
        console.log('success', user);
        someFunc();
      })
      .catch((error) => {
        console.log('error', error);
        someErrorFunc();
      });
  };
  // some more methods
  // render
}

export default NewAuthor;
