javascript - 如何检查主题中的“测试邮件”？我想写一个量角器测试来验证是否收到电子邮件

Question

这是我在 conf.js 文件中的 onPrepare() 函数。

onPrepare: function () {

        var mailListener = new MailListener({
            username: "email_address",
            password: "password",
            host: "imap.gmail.com",
            port: 993, // imap port
            tls: true,
            // connTimeout: 10000, // Default by node-imap
            // authTimeout: 5000, // Default by node-imap,
            debug: console.log, // Or your custom function with only one incoming argument. Default: null
            tlsOptions: { rejectUnauthorized: false },
            mailbox: "INBOX", // mailbox to monitor
            searchFilter: ["UNSEEN", ["FROM", "[e-mail]"],["SUBJECT","test mail"]], // 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(); // start listening

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

        global.mailListener = mailListener;
    },

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

我有一个用 mail.js 文件编写的辅助函数

'use strict';

const { browser } = require("protractor");

var Mail = function () {

    this.getLastEmail = function () {

        var deferred = protractor.promise.defer();
        console.log("Waiting for an email...");

        mailListener.on("mail", function (mail) {
            console.log("inside maillistener....")
            deferred.fulfill(mail);
        });

        return deferred.promise;
    }
}

module.exports = new Mail();

我有一个功能要测试，它会在提交表单后发送电子邮件。我想测试收件人是否收到了电子邮件。测试如下：

describe("Form submission.", function () {

    it("should test whether an email is received.", function () {
        /**
         * 
         * Here comes the code up to the plan submission
         */


        mail.getLastEmail().then(function(email) {
            expect(email.subject).toEqual("Critical Security alert");
        });
        
    });
});

所以通常测试应该失败并显示错误消息

expected "test mail" to equal "Critical Security alert"

但即使没有收到电子邮件，它也会通过。

我相信您在这里缺少 return 关键字

describe("Form submission.", function () {

    it("should test whether an email is received.", function () {
        ...
        return mail.getLastEmail().then(function(email) {
            expect(email.subject).toEqual("Critical Security alert");
        });
        
    });
});
