在量角器测试用例中从电子邮件获取值 [英] Fetching values from email in protractor test case

问题描述

我需要测试一个量角器测试用例，其中用户注册，收到一封电子邮件，转到电子邮件中提供的链接，并在激活注册表单中填写他/她的详细信息。

I need to test a protractor test case in which a user signs up, receives an email, goes to the link provided in the email and fills up his/her details in activation signup form.

问题是如何从电子邮件获取兑换令牌。我的电子邮件具有指向激活页面的链接，该页面具有如下所示的身份验证令牌：

The problem is how can I get the redeem token from the email. My email has a link to the activation page which has the auth token like following:

http://127.0.0.1:3000/#/signup/redeem/eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJqdGkiOiJlOTRhYzY3MC1kYTNlLTQyYTUtODVkZS02NDU4ZjVmZGMwYjAiLCJzdWIiOiJ0ZXN0QGNvZWYuY28iLCJpYXQiOjE0Mjc0OTM5MDMsImV4cCI6MTQyODA5ODcwM30.

但是如何获取该令牌，以便我可以构建网址或如何点击该按钮在我的电子邮件中，以便我可以完成流程？我正在使用mailcatcher来模拟电子邮件。

But how do I fetch that token so that I can build the url or how can I click that button in my email so that I can complete the flow ? I am using mailcatcher to simulate email.

推荐答案

这是我最近解决的问题。希望解决方案也适用于您的用例。

This is something I've solved recently. Hope the solution would also apply for your use-case.

先决条件：

• mail-listener2 包


• 了解承诺的概念

• mail-listener2 package
• understanding of the concept of promises

一步一步说明：

1. 安装 mail-listener2 ：

npm install mail-listener2 --save-dev

在您的量角器配置初始化邮件侦听器并使其在全球范围内可用：

In your protractor config initialize Mail Listener and make it available globally:

onPrepare: function () {
    var MailListener = require("mail-listener2");

    // here goes your email connection configuration
    var mailListener = new MailListener({
        username: "imap-username",
        password: "imap-password",
        host: "imap-host",
        port: 993, // imap port 
        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");
    });

    global.mailListener = mailListener;
}),

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

创建助手 getLastEmail（） 功能，将等待电子邮件：

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

    mailListener.on("mail", function(mail){
        deferred.fulfill(mail);
    });
    return deferred.promise;
};

示例测试用例：

Example test case:

describe("Sample test case", function () {

    beforeEach(function () {
        browser.get("/#login");
        browser.waitForAngular();
    });

    it("should login with a registration code sent to an email", function () {
        element(by.id("username")).sendKeys("MyUserName");
        element(by.id("password")).sendKeys("MyPassword");
        element(by.id("loginButton")).click();

        browser.controlFlow().await(getLastEmail()).then(function (email) {
            expect(email.subject).toEqual("New Registration Code");
            expect(email.headers.to).toEqual("[e-mail]");

            // extract registration code from the email message
            var pattern = /Registration code is: (\w+)/g;
            var regCode = pattern.exec(email.text)[1];

            console.log(regCode);

         });
    });
});
