Question

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

我正在使用NextJS来构建我的应用程序，也正在使用TypeScript。因此，没有我编辑的Webpack文件，Next可以处理。完整的package.json如下。

我的超级简单测试（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：

是否有任何抱怨的理由？

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() });

Answer 1

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

Answer 2

要使其正常工作，我需要将测试移至根目录__tests__中。然后像这样导入组件：

import Astronaut from '../components/Astronaut/Astronaut.tsx';

开玩笑找不到我的测试中导入的组件
