ReferenceError:在Jest环境被拆除后，您正在尝试“导入"文件:在loadCjsDefault [英] ReferenceError: You are trying to `import` a file after the Jest environment has been torn down: at loadCjsDefault

问题描述

我正在测试使用Jest构建具有汇总功能的捆绑软件，每当我使用async/await时都会抛出错误.我不知道怎么了我尝试了不同的方法，但都无法正常工作.

I am testing building a bundle with rollup using jest which throws error whenever i use async/await. I have no idea what's wrong. I tried different soultions and it's not working.

ReferenceError: You are trying to `import` a file after the Jest environment has been torn down.

      watchFiles: [
        'D:\\projects\\js\\published\\builderz\\test\\samples\\pure\\src\\index.js'
      ]
    }".

这是测试文件

import { resolve } from "path";
import builderz from "../src";

jest.useFakeTimers();

describe("production", () => {
  it("test pure js", async () => {
    await builderz({
      isSilent: true,
      paths: [resolve(__dirname, "./samples/pure")]
    });

    // update it later of cource:
    expect(true).toEqual(true);
  });
});

还有babel.config

And babel.config

module.exports = api => {
  api.cache(true);
  return {
    presets: [
      [
        "@babel/preset-env",
        {
          targets: {
            node: "current"
          }
        }
      ]
    ]
  };
};

推荐答案

在package.json中的 jest 键中添加"testEnvironment":"jsdom" >

Add "testEnvironment": "jsdom" into jest key in package.json

"jest": {
  "testEnvironment": "jsdom",
  "preset": "react-native",
  ...
