javascript - Jest 找不到在我的测试中导入的组件

Question

我的分支: https://github.com/Futuratum/moonholdings.io/tree/JestTests

我正在使用 NextJS构建我的应用程序，并使用 TypeScript。所以没有我编辑的 Webpack 文件，Next 会处理它。下面是完整的 package.json。

我 super 简单的测试(在 VSCode 中没有错误):

import React from 'react';
import { shallow } from 'enzyme';
import toJson from 'enzyme-to-json';

import Astronaut from './Astronaut';

describe('<Astronaut /> component', () => {
  console.log('Astronaut', Astronaut);
  describe('when rendering', () => {
    const wrapper = shallow(<Astronaut {...props} />);

    it('should render a component matching the snapshot', () => {
      const tree = toJson(wrapper);
      expect(tree).toMatchSnapshot();
      expect(wrapper).toHaveLength(1);
    });
  });
});

文件夹结构:

错误:

有没有想过它为什么会提示？

我的 Jest 配置:

"jest": {
    "setupTestFrameworkScriptFile": "<rootDir>/jest.setup.js",
    "testPathIgnorePatterns": [
      "<rootDir>/.next/",
      "<rootDir>/node_modules/"
    ],
    "transform": {
      "\\.(gql|graphql)$": "jest-transform-graphql",
      ".*": "babel-jest",
      "^.+\\.js?$": "babel-jest"
    }
  }

jest.setup.js

import { configure } from 'enzyme';
import Adapter from 'enzyme-adapter-react-16';

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

您还可以将 __tests__ 文件夹放在 Astronaut 文件夹中，然后将 Austronaut.tsx 作为“../Astronaut.tsx”导入到您的测试中。
