Jest: Describe.each for asynchronous collection?

Question

JavaScript

It is necessary to make a set of tests for the collection received asynchronously.

I try like this:

let collection = [];
beforeAll( async() => {  collection = await getAsyncCollection() }

describe.each(collection)("Test summary for collection", (item)=>{
     // ...  и вот сюда мы не попадаем, потому  что сначала отрабатывает each на пустой коллекции, а потом уже beforeAll получает коллекци. 
})

How to make Describe for an asynchronous collection and why does each work before beforeAll ?
