如何在Mocha测试中添加自定义成功消息？

const assert = require('chai').assert;
const { customSuccessMessage } = require('./utils'); // 自定义的测试辅助函数

describe('My Test Suite', function() {
  it('should pass the test with a custom success message', function() {
    assert.equal(2 + 2, 4, customSuccessMessage('Addition')); // 使用自定义的测试辅助函数
  });
});

function customSuccessMessage(testName) {
  return `Test "${testName}" passed successfully!`;
}

module.exports = {
  customSuccessMessage
};
