Javascript 存根连接中间件

我有一个中间件（coffeescript）：

如何存根basicAuth函数以控制流量

我试过：

express = require 'express'
sinon.stub express, 'basicAuth'

和获取错误：

 TypeError: Cannot set property basicAuth of function createApplication() {
  var app = connect();
  utils.merge(app, proto);
  app.request = { __proto__: req };
  app.response = { __proto__: res };
  app.init();
  return app;
} which has only a getter

我也尝试过：

connect = require 'connect'
sinon.stub connect, 'basicAuth'

---

哪些错误是因为connect不是my app的直接可用依赖项（express需要它）

您可以创建自己的模块，该模块将导出您希望存根的方法

# stub.coffee
express = require 'express'

# export basicAuth as a stub-friendly export
module.exports.basicAuth = express.basicAuth

您可能需要这个，而不是express

stubpress = require 'stubbableExpress'

basic = (req, res, next) ->
  return next() if not app.settings.auth?
  stubpress.basicAuth(app.settings.auth.username, app.settings.auth.password) req, res, next

这给了你一些你能理解的东西：

stubpress = require 'stubbableExpress'
sinon.stub(stubpress, 'basicAuth')

stubpress = require 'stubbableExpress'
sinon.stub(stubpress, 'basicAuth')
