如何在webpack 2中集成mocha单元测试？

const assert = require('assert');
const { add } = require('../src/utils');

describe('Utils', () => {
  it('should return the sum of two numbers', () => {
    assert.strictEqual(add(1, 2), 3);
  });
});

const path = require('path');

module.exports = {
  entry: './src/index.js',
  output: {
    filename: 'bundle.js',
    path: path.resolve(__dirname, 'dist'),
  },
  module: {
    rules: [
      // 添加babel-loader，用于处理ES6语法
      {
        test: /\.js$/,
        exclude: /node_modules/,
        use: {
          loader: 'babel-loader',
          options: {
            presets: ['@babel/preset-env'],
          },
        },
      },
    ],
  },
};

{
  "name": "my-app",
  "version": "1.0.0",
  "scripts": {
    "test": "mocha test/test.js",
    "build": "webpack"
  },
