如何使用带有watch选项的mocha运行eslint？

npm install --save-dev mocha eslint

const Mocha = require('mocha');
const { CLIEngine } = require('eslint');

const mocha = new Mocha();
const cli = new CLIEngine({
  // ESLint配置选项
  configFile: '.eslintrc',
  fix: true, // 自动修复错误
});

// 添加需要测试的文件
mocha.addFile('path/to/test/file.js');

// 在运行测试之前，运行ESLint检查代码
mocha.before(function (done) {
  const report = cli.executeOnFiles(['path/to/test/file.js']);
  const formatter = cli.getFormatter();

  if (report.errorCount > 0) {
    console.log(formatter(report.results));
    process.exit(1);
  }

  done();
});

// 运行测试
mocha.run(function (failures) {
  process.exitCode = failures ? 1 : 0;
});
