firebase - Jest Test - 当前环境不支持指定的持久化类型

Question

我使用 jest 在我的 Create React App 上使用 Firebase Web SDK 和 FirebaseUI 运行一些测试

每当我尝试使用 --env=jsdom 运行一些测试时 - 我都会遇到:The current environment does not support the specified persistence type.似乎与 Auth 有关

是否有任何已知的相关问题/解决方法？除了测试之外，代码似乎可以正常工作/编译。

谷歌没有多大帮助

这是测试，非常基本。
必须添加 import "firebase/storage";因此:firebase.storage() is not a function in jest test cases

提前致谢

import React from "react";

import Enzyme from "enzyme";
import Adapter from "enzyme-adapter-react-16";
import "firebase/storage";
import {filterIngredientsToRemove} from "./shoppingList-reducer";

Enzyme.configure({adapter: new Adapter()});

describe("", () => {
    let shoppingList;
    let recipeId;

    beforeEach(() => {
        shoppingList = {
            shoppingListItems: {
                "1234": {ingredientId: 987, name: "patate", recipeId: 1234},
                "2345": {ingredientId: 987, name: "patate", recipeId: 5432}
            },
            shoppingListRecipes: {
                "1234": {portion: 3}
            }
        };

        recipeId = 1234;
    });

    it("should filter out the shoppinglistItems with the provided recipeId", () => {
        const result = filterIngredientsToRemove(recipeId, shoppingList.shoppingListItems);
        expect(result).toEqual([{ingredientId: 987, name: "patate", recipeId: 1234}]);
    });
});

您是否在 Firebase 配置中设置了持久性？测试环境不支持持久化，所以你可以做这样的事情来规避它:

firebase.auth().setPersistence(process.env.NODE_ENV === 'test' 
  ? firebase.auth.Auth.Persistence.NONE 
  : firebase.auth.Auth.Persistence.LOCAL);
