javascript - 在IntelliJ IDEA中运行Jest测试

我创建了一个create-react-app版本1.4.0的React应用，并在IntelliJ中打开了生成的项目。现在，我也尝试在IntelliJ中运行生成的测试。这样做时，我得到以下输出：

/usr/bin/node /home/l/src/hello-react/node_modules/jest/bin/jest --config {\"rootDir\":\"/home/l/src/hello-react\",\"transformIgnorePatterns\":[\"/node_modules/\",\"^/home/l/bin/idea-IU-172.3544.35/plugins/JavaScriptLanguage/helpers\"],\"unmockedModulePathPatterns\":[\"^/home/l/bin/idea-IU-172.3544.35/plugins/JavaScriptLanguage/helpers\"]} --colors --setupTestFrameworkScriptFile /home/l/bin/idea-IU-172.3544.35/plugins/JavaScriptLanguage/helpers/jest-intellij/lib/jest-intellij-jasmine.js --testPathPattern ^/home/l/src/hello\-react/src/App\.test\.js$ --testNamePattern "^(test )?renders without crashing$"

我只运行生成的代码。我没有修改它或编写任何自己的代码。为了能够在IntelliJ IDEA中运行此测试，我需要做什么？

作为参考，以下是重要文件：

App.test.js

import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';

it('renders without crashing', () => {
  const div = document.createElement('div');
  ReactDOM.render(<App />, div);
});

App.js

import React, { Component } from 'react';
import logo from './logo.svg';
import './App.css';

class App extends Component {
  render() {
    return (
      <div className="App">
        <div className="App-header">
          <img src={logo} className="App-logo" alt="logo" />
          <h2>Welcome to React</h2>
        </div>
        <p className="App-intro">
          To get started, edit <code>src/App.js</code> and save to reload.
        </p>
      </div>
    );
  }
}

export default App;

package.json

{
  "name": "hello-react",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "react": "^16.0.0",
    "react-dom": "^16.0.0",
    "react-scripts": "1.0.13"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test --env=jsdom",
    "eject": "react-scripts eject"
  }
}

最佳答案

在“ Jest Run”配置中，选择：

jest-package: react-scripts
jest options: --env=jsdom
