Javascript 无法在量角器中检索电子邮件信息

参考问题中的信息，我仍然无法参考电子邮件。在我的测试用例中，“expect”没有被执行，原因不明

如果我用这条线

browser.controlFlow().await(getLastEmail()).then(...)

存在“browser.controlFlow（…）.await不是函数错误”

conf.js

var MailListener = require("mail-listener2")

exports.config = {
framework: 'jasmine2',
specs: ['./test.js'],
jasmineNodeOpts: { defaultTimeoutInterval: 360000 },
allScriptsTimeout: 60000,

onPrepare: function () {

    var mailListener = new MailListener({
        username: "username",
        password: "password",
        host: "imapPort",
        port: 993, // imap port
        secure: true,
        tls: true,
        tlsOptions: { rejectUnauthorized: false },
        mailbox: "INBOX", // mailbox to monitor
        searchFilter: ["UNSEEN", "FLAGGED"], // the search filter being used after an IDLE notification has been retrieved
        markSeen: true, // all fetched email willbe marked as seen and not fetched next time
        fetchUnreadOnStart: true, // use it only if you want to get all unread email on lib start. Default is `false`,
        mailParserOptions: {streamAttachments: true}, // options to be passed to mailParser lib.
        attachments: true, // download attachments as they are encountered to the project directory
        attachmentOptions: { directory: "attachments/" } // specify a download directory for attachments
    })

    mailListener.start()

    mailListener.on("server:connected", function(){
        console.log("Mail listener initialized")
    })

    mailListener.on("error", function(err){
      console.log(err)
    })

    mailListener.on("server:disconnected", function(){
      console.log("imapDisconnected")
    })

    global.mailListener = mailListener
},

onCleanUp: function () {
    mailListener.stop()
 }
}

测试用例：

describe('Email Testing', function () {

 it('should login with a registration code sent to an email', function () {
   //this line causes a 'browser.controlFlow(...).await is not a function' error
  // browser.controlFlow().await(getLastEmail()).then(function (email) {
  getLastEmail().then(function (email) {
    // The expect does not get executed as it should fail
    expect(email.subject).toEqual('My Subject')
   })
 })
})

 function getLastEmail () {
   var deferred = protractor.promise.defer()
   console.log('Waiting for an email...')

   mailListener.on('mail', function (mail) {
     console.log('No Console Log Here!')
     deferred.fulfill(mail)
   })
  return deferred.promise
 }

我不确定我的测试用例中缺少了什么才能阅读邮件的主题或正文？

您基本上必须将异步代码包装在承诺中，并将承诺/函数传递到流中。execute（）

今天遇到了同样的问题。原来webdriver和ControlFlow的API已经更新，wait已经更改为wait。是的，细微的差别。请参见此处的新API参考：

要为等待条件安排任务，请将代码更改为如下所示：

browser.controlFlow().wait(getLastEmail()).then(...)

您使用的量角器版本是什么？我使用的是量角器3.1.1您好，我在使用量角器@3.1.1时看到相同的错误“browser.controlFlow（…）。wait不是函数”。如果有人已经有了解决方案，请您提出建议。

browser.controlFlow().wait(getLastEmail()).then(...)
