节点unit testing – TypeError：无法读取未定义的属性“顺序”

我收到以下错误， Error: BLANKET-Error parsing instrumented code: TypeError: Cannot read property 'order' of undefined我的testing代码Error: BLANKET-Error parsing instrumented code: TypeError: Cannot read property 'order' of undefined指示其中testedModule = proxyquire('../index', {

任何人都可以看到为什么我得到这个错误？

我的testing文件：

  pattern: function (filename) { return !/node_modules/.test(filename); } }); // in terminal, type the following command to get code coverage: mocha -R html-cov > coverage.html var chai = require('chai'); var sinonChai = require("sinon-chai"); var sinon = require('sinon'); chai.use(sinonChai); var proxyquire = require('proxyquire').noCallThru(); var expect = chai.expect; var mockDir = require('mock-fs'); var extend = require('lodash').extend; describe("Invoicer", function () { describe("Success call", function () { var fileReader = require('../fileReader'); var getObject = require('../getObject'); var sendEmail = require('../sendEmail'); var baseEvent = { order: "http://orange/order/1234", email: '<[e-mail]>' }; var testedModule, fakePath, fakeTemplate, fakeData, fakeMessage, eventObj, fileReaderStub, getObjectStub, sendEmailStub, callbackSpy; before(function () { eventObj = extend({}, baseEvent); fileReaderStub = sinon.stub(fileReader, 'read'); getObjectStub = sinon.stub(getObject, '_get'); sendEmailStub = sinon.stub(sendEmail, '_send'); callbackSpy = sinon.spy(); testedModule = proxyquire('../index', { './fileReader': { 'read': fileReaderStub }, './getObject': { '_get': getObjectStub }, './sendEmail': { '_send': sendEmailStub } }); fakePath = "path/to/file.html"; fakeMessage = "Email sent"; fakeTemplate = "WhatcanIsay"; fakeData = "Hello World"; getObjectStub.callsArgWith(1, null, fakeData); fileReaderStub.callsArgWith(2, null, fakeTemplate); sendEmailStub.callsArgWith(2, null, fakeMessage); testedModule.Invoicer(eventObj, {done: function (error, result) { console.log("Here!"); callbackSpy.apply(null, arguments); }}); }); after(function () { fileReader.read.restore(); getObject._get.restore(); sendEmail._send.restore(); }); it("context.done is called with no error", function () { expect(callbackSpy).has.been.called; }); }); }); 

这是index.js

 'use strict'; var async = require('async'); var obj = require("./config.json"); var fileReader = require('./fileReader'); var _readFile = fileReader.read; var getObject = require('./getObject'); var _getObject = getObject._get; var sendEmail = require('./sendEmail'); var _sendEmail = sendEmail._send; exports.Invoicer = function (event, context) { console.log("Order: %s", event.order); console.log("Email: %s", event.email); var urlPath = event.order; // process.argv[2]; // The url for the order endpoint var _recipient = event.email; //process.argv[3]; // The recipient of the email var _filePath = obj.filePath; async.waterfall([ function retrieveObject (next) { console.log("waterfall getobject"); _getObject(urlPath, next); }, function _readF (data, next) { console.log("waterfall reafile"); _readFile(data, _filePath, next); }, function sendsEmail (popHtml, next) { console.log("waterfall sendemail"); _sendEmail(popHtml, _recipient, next); } ], function (error, result) { if (error) { console.log("Error waterfall"); return; context.done(error); } else { console.log("Done!"); return; context.done(result); } }); }; if (!process.env.LAMBDA_TASK_ROOT) { exports.Invoicer(); }

这个代码path是否被执行？ 如果是这样，它会抛出这个错误，因为你没有传递任何参数，因此event.order会导致TypeError: undefined

 if (!process.env.LAMBDA_TASK_ROOT) { exports.Invoicer(); }
