量角器如何首先运行登录测试脚本 [英] Protractor how to run login test script first

问题描述

我正在尝试使用量角器测试Angular Single Page应用程序.我需要先运行登录脚本.只有这样，我才能转到其他路线，因为在更改路线的localStorage中检查了令牌.

I am trying to test an Angular Single Page application with protractor. I need to run the login script first. Only then I can move to other routes since there is a check for token in localStorage on route change.

此测试方法是否正确?在这种情况下，我需要先运行登录脚本.量角器是否可以控制规格文件的顺序.

Is this testing approach correct?. In that case I need to run the login script first. Does protractor allows to control the spec file order.

或者我应该通过在localStorage中对令牌进行硬编码来独立运行每个脚本(我应该在每次测试之前独立地登录api调用).

Or should I run the each script independently by hardcoding the token in localStorage (Should I do login api call independently before each test).

我的登录脚本包含以下内容

My login script contains the following

it('Login with wrong email', function() {

})

it('Login with correct email', function() {

})

因此，在运行Login with correct mail之后，我将获得accessToken，该令牌将存储在localStorage中，并且我可以继续测试其他路由.这是正确的方法吗?如果没有，我该如何使用端到端的登录测试单个应用程序.

So after running the Login with correct mail I will get the accessToken which will get stored in localStorage and I can continue testing other routes. Is this the correct approach. If not how do I test a single application with login from end to end.

在量角器样式指南中，它被称为

使测试彼此独立

Make your tests independent from each other

所以我应该使用beforeAll, beforeEach来获取访问令牌并在每次测试之前存储在localStorage中.在这种情况下，请向我解释该怎么做.

So should I use beforeAll, beforeEach to get the access token and store in localStorage before each test. In that case please explain me how to do it.

非常感谢您的帮助.

谢谢.

推荐答案

如量角器中突出显示的常见问题解答，您可以在conf文件的onPrepare部分中指定登录代码.这是一个示例.

As highlighted in the Protractor FAQs, you can specify your login code in the onPrepare section of your conf file. Here is an example.

您也可以在beforeAll中实现此目的，但这会给测试脚本增加不必要的开销.可以更改localStorage，但不能改变e2e测试的精神，因为LS可能导致很多错误，最终您会怀疑是由您的应用还是LS修改代码引起的.

You can also achieve this in beforeAll but that adds unnecessary overhead to your test scripts. Altering the localStorage is possible, but not in the spirit of e2e testing since a lot can go wrong wrt LS, and you will end up wondering if it is your app or your LS modification code that caused this.
