Node.js 如何重构MochaBDD测试？

我的解决方案不起作用

const port = require('../app').port
const superagent = require('superagent')
const expect = require('expect')
const server = require('http').createServer(app)

const boot = () => {
  server.listen(app.get('port'), () => {
    console.info(`Express server listening on port ${app.get('port')}`)
  })
}

当我尝试

mocha tests
Express.js server is listening on port 3000

ReferenceError: app is not defined

OP建议这样做

const server = http.createServer(app)

但在这种情况下，我得到了输出

ReferenceError: http is not defined

如何解决此问题？

您需要实际导入

应用程序

-模块才能使用它。像这样的方法应该会奏效：

const app = require('../app'); // adjust the path if necessary
const superagent = require('superagent')
const expect = require('expect')
const server = require('http').createServer(app)

const boot = () => {
  server.listen(app.get('port'), () => {
    console.info(`Express server listening on port ${app.get('port')}`)
  })
}
