如何在文件之外读取mocha测试套件/用例名称？

const Mocha = require('mocha');

const mocha = new Mocha();

const suiteNames = []; // 保存测试套件名称的数组
const testNames = []; // 保存测试用例名称的数组

mocha.suite.beforeEach(function () {
  const currentSuite = this.currentTest.parent.title;
  if (!suiteNames.includes(currentSuite)) {
    suiteNames.push(currentSuite);
  }
});

mocha.suite.beforeEach(function () {
  const currentTest = this.currentTest.title;
  if (!testNames.includes(currentTest)) {
    testNames.push(currentTest);
  }
});

// 添加测试文件
mocha.addFile('test.js');

// 运行测试
mocha.run(function () {
  // 在此处可以访问suiteNames和testNames数组，获取测试套件和用例名称
});

const fs = require('fs');

// ...

mocha.run(function () {
  const suiteNamesString = suiteNames.join('\n');
  const testNamesString = testNames.join('\n');

  // 将测试套件名称写入文件
  fs.writeFile('suiteNames.txt', suiteNamesString, function (err) {
    if (err) throw err;
    console.log('Suite names saved to suiteNames.txt');
  });

  // 将测试用例名称写入文件
  fs.writeFile('testNames.txt', testNamesString, function (err) {
    if (err) throw err;
    console.log('Test names saved to testNames.txt');
  });
});
