将express中间件函数与sinon进行存根

说明

我尝试为一个express中间件函数设置存根赝品,但这并没有结束。

我在试着用锡农的存根 callsFake

即使我需要模块并在导出时替换属性中的函数。我一直看到原来的功能行为。

我知道我应该在设置中间件函数之前尝试将函数存根,这就是express app 首先导入。

api/middlewares/stripe/signature .

const stripeHelper = require('../../../lib/stripe')
const logger = require('../../../lib/logger')
const verifySignature = (req, res, next) => {
  var event
  let eventName = req.url.replace('/', '')
  try {
      // Try adding the Event as `request.event`
    event = stripeHelper.signatureCheck(
        eventName,
        req.body,
        req.headers['stripe-signature']
      )
  } catch (e) {
      // If `constructEvent` throws an error, respond with the message and return.
    logger.error('Error while verifying webhook request signature', e.message, e)
    return res.status(400).send('Webhook Error:' + e.message)
  }
  req.event = event
  next()
}
module.exports.verifySignature = verifySignature

我已经试过了

• 设置多个 beforEach 钩子以组织我的存根和前提条件或测试

不断发生的事情

• 执行原始的中间件功能
• 我没有看到任何存根函数的日志(作为sinon存根不工作的第二个证明)

这是我的存根和测试挂钩设置:

const chai = require('chai')
const chaiHttp = require('chai-http')
const dirtyChai = require('dirty-chai')
const sinon = require('sinon')
const decache = require('decache')
const signatureMiddleware = require('../../../api/middlewares/stripe/signature')
const bp = require('body-parser')
let verifySignatureStub, rawStub

chai.should()
chai.use(dirtyChai)
chai.use(chaiHttp)

const API_BASE = '/api/subscriptions'
const planId = 'NYA-RUST-MONTHLY'
const utils = require('../../utils')
const {
  hooks: {createSubscription, emitPaymentSucceeded},
  stripe: {generateEventFromMock}
} = utils

let testUser, testToken, testSubscription, server

describe.only('Subscriptions renewal (invoice.payment_succeeded)', function () {
  this.timeout(30000)

  beforeEach(function (done) {
    createSubscription(server, {planId}, function (err, resp) {
      if (err) return done(err)
      const {user, jwt, subscription} = resp
      console.log(user, jwt)
      testUser = user
      testToken = jwt
      testSubscription = subscription
      done()
    })
  })

  beforeEach(function (done) {
    verifySignatureStub = sinon.stub(signatureMiddleware, 'verifySignature')
    rawStub = sinon.stub(bp, 'raw')
    rawStub.callsFake(function (req, res, next) {
      console.log('bp raw')
      return next()
    })
    verifySignatureStub.callsFake(function (req, res, next) {
      const {customerId} = testUser.stripe
      const subscriptionId = testSubscription.id
      console.log('fake verify')
      req.event = generateEventFromMock('invoice.payment_failed', {subscriptionId, customerId, planId})
      return next()
    })
    done()
  })

  beforeEach(function (done) {
    decache('../../../index')
    server = require('../../../index')
    const {customerId} = testUser.stripe
    const {id: subscriptionId} = testSubscription
    console.log(`emitting payment succeeded with ${customerId}, ${subscriptionId} ${planId}`)
    emitPaymentSucceeded(server, testToken, function (err, response) {
      if (err) return done(err)
      done()
    })
  })

  afterEach(function (done) {
    verifySignatureStub.restore()
    done()
  })

  it('Date subscription will renew gets set to a valid number roughly one month', function () {
    // Not even getting here becasue calling the original function contains verifyMiddleware which should be replaced
  })

  it('Current period end is modified')

  it('An invoice for the new starting period is generated')

  it('Subscription status keeps active')
})

所有运行在节点8上,我用mocha运行测试,用dirty chai做了一个设置。
