Question

尝试解决我似乎无法将动态收集的数据传递给Mocha测试的问题。

以下是我的申请的逻辑：

客户提交他们的Github网址。请求Express / Node应用程序。
Express / Node应用程序获取repo和username并向Github API请求数据，并将文件内容作为base64添加到对象。
将包含文件的对象传递给相关的测试文件，然后执行。
处理结果并创建初步成绩。然后将这些发送回客户端。

以下是测试文件的外观：

    const chai = require('chai');
    const chaiSubset = require('chai-subset');
    chai.use(chaiSubset);
    const expect = chai.expect;
    const base64 = require('base-64');
    const HTML_CONTENT = require('../../00-sandbox-files/basic-portfolio-solution.json').html;
    const CSS_CONTENT = require('../../00-sandbox-files/basic-portfolio-solution.json').css;
    const decodedCSS = base64.decode(CSS_CONTENT[1].content);
    const cheerio = require('cheerio');
    const juice = require('juice');

    let decodedHTMLcontact;
    let decodedHTMLindex;
    let decodedHTMLportfolio;

    for (const obj in HTML_CONTENT) {
      if (HTML_CONTENT[obj].path == "contact.html") {
        decodedHTMLcontact = base64.decode(HTML_CONTENT[obj].content);
      } else if (HTML_CONTENT[obj].path == "index.html") {
        decodedHTMLindex = base64.decode(HTML_CONTENT[obj].content);
      } else if (HTML_CONTENT[obj].path == "portfolio.html") {
        decodedHTMLportfolio = base64.decode(HTML_CONTENT[obj].content);
      }
    }

    tests = function (html, css) {
      describe('HTML Elements tests that should pass for contact.html', function () {
        let $ = cheerio.load(decodedHTMLcontact);
        describe('HTML Elements that should exist in contact.html', function () {
          it('should contain a header element', function () {
            expect($('body').find('header').length).to.equal(1);
          });
          it('should contain a section element', function () {
            expect($('body').find('section').length).to.equal(1);
          });
          it('should contain several anchor elements', function () {
            expect($('nav').find('a').length).to.be.at.least(3, 'You need an additional anchor elements for your navigation elements');
          });
          it('should contain an h1 element', function () {
            expect($('body').find('h1').length).to.equal(1);
          });
          it('should contain a form element', function () {
            expect($('body').find('form').length).to.equal(1);
          });
          it('should contain a footer element', function () {
            expect($('body').find('footer').length).to.equal(1);
          });
        });

这是Mocha测试的执行文件：

const Mocha = require('mocha');

// Instantiate a Mocha instance.
const mocha = new Mocha();
const HW_PORTFOLIO_PATH = './server/05-run-testing-suite/HW-Week1-portfolio-wireframe/HW-1-portfolio.js';

function homeworkRouter(contentObj, repo) {
  switch (repo) {
    case "Basic-Portfolio":
      mocha.addFile(HW_PORTFOLIO_PATH);
      break;
    case "HW-Wireframe":
      mocha.addFile('./server/05-run-testing-suite/HW-Week1-portfolio-wireframe/HW-1-wireframe.js');
      break;
    default:
      console.log("No homework provided");
      break;
  }
}

module.exports = {

  // Run the tests and have info about what can be returned
  runTests: function(contentObj, repo) {
    homeworkRouter(contentObj, repo);
    console.log("Content Object", contentObj);
    console.log("Repo", repo);
    mocha.run()
    .on('fail', function (test, err) {
      console.log('Test fail');
      console.log(err);
    })
    .on('end', function () {
      console.log('All done');
    });
  }
}

我们提出的解决方案涉及使用vm（），将数据设置为全局变量，和/或构建和删除文件。我想要一个解决方案，它更高效，不会污染全球。

将数据传递给以编程方式运行的Mocha测试的最佳方法是什么？
