Javascript 如何在JS中设置一个函数返回的两个全局对象？

我是Javascript和Jest的新手，我有以下代码：

const foo = () => {
  const fun = //some function
  const obj = //some object
  //...
  return {fun, obj};
}

describe('Battery test', () =>
  let fun = ()=>{};
  let obj = {};
  beforeEach(() => {
    {fun, obj} = foo();
  }
}

这将生成错误：

Unexpected token

  > 36 |         {fun, obj} = foo();
       |                    ^                        

我想到的唯一超级丑陋的解决办法是：

describe('Battery test', () =>
  let fun = ()=>{};
  let obj = {};
  beforeEach(() => {
    const wrapper = foo();
    fun = wrapper.fun;
    obj = wrapper.obj;
  }
}

还有别的办法吗

 ({fun, obj} = foo());

需要将对象分解与block语句分开
