描述bug

为了上下文，这是我的问题 firebase/firebase-js-sdk#4552 。
从评论中可以看出，Jest似乎在加载Node二进制文件，而不是浏览器二进制文件。我曾在早期版本的Jest中看到过一个 --browser 命令，类似的问题参考了这个修复方法，但这在CRA中不再受支持/不可用。

你尝试恢复依赖了吗？

我已经尝试删除 package-lock.json 和 node_modules 。

你在用户指南中搜索了哪些术语？

依赖项、测试、浏览器、Node

重现问题的步骤

1. npx create-react-app test --template typescript
2. npm i firebase
3. 添加一个类似于下面的测试

test("firestore test", async () => {
  const app = firebase.initializeApp();
  const test = await app.firestore().collection("users").doc("test").get();
});

1. npm run test

预期行为

测试应该按预期运行并通过

实际行为

The error below may be caused by using the wrong test environment, see https://jestjs.io/docs/en/configuration#testenvironment-string.
    Consider using the "node" test environment.
