Polyfills Jest 测试失败类型 ErrorHandler = (error: mix, isFatal: boolean) => void;

我正在尝试使用 Jest 并仅测试渲染，这是我的测试文件：

import "react-native"; 
import React from "react"; 
import App from"../src/Root/"; 
import { create } from "react-test-renderer";

describe("App", () => {
 const tree = create(<App />).toJSON();  
 it("renders correctly", () => {
  expect(tree).toMatchSnapshot();
 }); 
});
