问题描述

我已经构建了一个邮件程序功能并试图支持覆盖范围.尝试测试它的一部分已经证明很棘手，特别是这个 mailer.smtpTransport.sendMail

I've got a mailer function I've built and trying to shore up the coverage. Trying to test parts of it have proven tricky, specifically this mailer.smtpTransport.sendMail

var nodemailer = require('nodemailer')

var mailer = {}

mailer.smtpTransport = nodemailer.createTransport('SMTP', {
    'service': 'Gmail',
    'auth': {
        'XOAuth2': {
            'user': '[email protected]',
            'clientId': 'googleClientID',
            'clientSecret': 'superSekrit',
            'refreshToken': '1/refreshYoSelf'
        }
    }
})
var mailOptions = {
    from: 'Some Admin <[email protected]>',
}

mailer.verify = function(email, hash) {
    var emailhtml = 'Welcome to TestCo. <a href="'+hash+'">Click this '+hash+'</a>'
    var emailtxt = 'Welcome to TestCo. This  is your hash: '+hash
    mailOptions.to = email
    mailOptions.subject = 'Welcome to TestCo!'
    mailOptions.html = emailhtml
    mailOptions.text = emailtxt
    mailer.smtpTransport.sendMail(mailOptions, function(error, response){
        if(error) {
            console.log(error)

        } else {
            console.log('Message sent: '+response.message)
        }
    })
}

我不确定如何进行测试，特别是确保我的 mailer.smtpTransport.sendMail 函数在不实际发送电子邮件的情况下传递正确的参数.我正在尝试使用 https://github.com/whatser/mock-nodemailer/tree/master，但我可能做错了.我应该嘲笑这个方法吗?

I'm unsure of how to go about testing, specifically ensuring that my mailer.smtpTransport.sendMail function is passing the correct parameters without actually sending the email. I'm trying to use https://github.com/whatser/mock-nodemailer/tree/master, but I'm probably doing it wrong. Should I be mocking out the method?

var _ = require('lodash')
var should = require('should')
var nodemailer = require('nodemailer')
var mockMailer = require('./helpers/mock-nodemailer')
var transport = nodemailer.createTransport('SMTP', '')

var mailer = require('../../../server/lib/account/mailer')

describe('Mailer', function() {
    describe('.verify()', function() {
        it('sends a verify email with a hashto an address when invoked', function(done) {
            var email ={
                'to': '[email protected]',
                'html': 'Welcome to Testco. <a href="bleh">Click this bleh</a>',
                'text': 'Welcome to Testco. This  is your hash: bleh',
                'subject': 'Welcome to Testco!'
            }

            mockMailer.expectEmail(function(sentEmail) {
            return _.isEqual(email, sentEmail)
            }, done)
            mailer.verify('[email protected]','bleh')
            transport.sendMail(email, function() {})
    })
})

推荐答案

您可以在测试中使用存根"传输层而不是 SMTP.

You can use a 'Stub' transport layer on your test instead of SMTP.

var stubMailer = require("nodemailer").createTransport("Stub"),
    options = {
        from: "[email protected]",
        to: "[email protected]",
        text: "My Message!"
    };

   stubMailer.sendMail(options, function(err, response){
     var message = response.message;
   })

因此，在这种情况下，消息"将是文本格式的电子邮件.像这样:

So, in that case, 'message' will be the email in text format. Something like this:

MIME-Version: 1.0
X-Mailer: Nodemailer (0.3.43; +http://www.nodemailer.com/)
Date: Fri, 25 Feb 2014 11:11:48 GMT
Message-Id: <123412341234.e23232@Nodemailer>
From: [email protected]
To: [email protected]
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: quoted-printable

My Message!
