我如何用量角器瓦特/柴作为许诺的处理承诺的数组 [英] How do I handle an array of promises using Protractor w/ chai-as-promised

问题描述

我使用的量角器是 CucumberJS 和柴AS-承诺（假设CucumberJS不具有一个内置的断言库）建立一个自动化测试套件。

一切正常单断言（使用期待的功能钗-AS-承诺）。我遇到了麻烦，但是，试图处理相同的测试（步）内的多个承诺的时候。在下面的例子中，verifyUserFirstName返回映射到特定行的td.getText承诺（）。

  this.Then（/ ^我应该可以看到正确的价值观我的用户条目列表$ /，函数（回调）{
    期待（usersPage.verifyUserFirstName（'[e-mail]'））to.eventually.equal。（'托尼'）;
    期待（usersPage.verifyUserLastName（'[e-mail]'））to.eventually.equal。（'裴'）;
    期待（usersPage.verifyUserPhone（'[e-mail]'））to.eventually.equal。（'8764309111'）;
    回电话（）;
 

目前，当任何期望（）线失败，量角器将退出并离开浏览器窗口挂不运行测试的其余部分。

在具有只是一个单一的期望（）的一个步骤失败了（见下面的例子），一切都完美。它被记录为失败的步骤，以及量角器继续试验的其余部分运行到完成。有没有人经历过这个？

  this.Then（/ ^我应直接向用户列表页$ /，函数（回调）{
    expect(browser.getCurrentUrl()).to.eventually.equal('http://localhost:9001/#/nav/').and.notify(callback);
}）;
 

解决方案

我有同样的挑战，我这是怎么解决的：

  this.Then（/ ^我应该可以看到正确的价值观我的用户条目列表$ /，函数（回调）{
    VAR verifyUser = Q.all（[
        usersPage.verifyUserFirstName（'[e-mail]'），
        usersPage.verifyUserLastName（'[e-mail]'），
        usersPage.verifyUserPhone（'[e-mail]'）
    ]）;
    期待（verifyUser）.to​​.eventually.deep.equal（['托尼'，'裴'，'8764309111'）and.notify（回调）。
}
 

我希望帮助！

I am using Protractor with CucumberJS and chai-as-promised (given that CucumberJS does not have a built-in assertions library) to build an automated test suite.

Everything works fine for single assertions (using the expect feature of chai-as-promised). I run into trouble, however, when attempting to handle multiple promises within the same test (step). In the following example, verifyUserFirstName returns a promise mapped to a certain row's td.getText().

this.Then(/^I should see my user entry with proper values in the list$/, function (callback) {
    expect(usersPage.verifyUserFirstName('[e-mail]')).to.eventually.equal('Tony');
    expect(usersPage.verifyUserLastName('[e-mail]')).to.eventually.equal('Bui');
    expect(usersPage.verifyUserPhone('[e-mail]')).to.eventually.equal('8764309111');
    callback();

Currently, when any of the expect() lines fail, Protractor will exit and leave the browser window hanging without running the rest of the tests.

When a step featuring just a single expect() fails (see example below), everything works perfectly. It is logged as a failed step, and Protractor continues to run the rest of the tests to completion. Has anyone experienced this?

this.Then(/^I should be directed to the user list page$/, function (callback) {
    expect(browser.getCurrentUrl()).to.eventually.equal('http://localhost:9001/#/nav/').and.notify(callback);
});

解决方案

I had same challenge, this is how I solved:

this.Then(/^I should see my user entry with proper values in the list$/, function (callback) {
    var verifyUser = Q.all([
        usersPage.verifyUserFirstName('[e-mail]'),
        usersPage.verifyUserLastName('[e-mail]'),
        usersPage.verifyUserPhone('[e-mail]')
    ]);
    expect(verifyUser).to.eventually.deep.equal(['Tony', 'Bui', '8764309111').and.notify(callback);
}

I hope that helps!
