在Ember App Kit中测试ember-simple-auth

Question

I'm attempting to perform integration/acceptance tests for my Ember app. I'm specifically testing user authentication (eg – submitting the login form) and protected pages/states that require authenticated users.

General notes about my app:

• Using Ember App Kit
• Using ember-simple-auth for authentication
• I have api-stubs for my ember-simple-auth forms to hit using the Devise authorizer. These work fine when running the app in-browser.

I have three problems:

1. Devise Authenticator & Ephemeral Storage

From the ember-simple-auth API, it refers to using Ephemeral storage for tests. I have done so, much like this . However, it seems that the sessions is still getting stored in local storage. If I do not perform localStorage.clear() in each test setup/teardown tests fail because I remain logged in when each test runs after the first.

Am I able to prevent storing the session in local storage between each test when I'm using the Devise authenticator for my app?

2. Multiple Acceptance Tests

If I attempt to log in a user in more than 1 test() , my tests spin off into an infinite loop. The first test will pass, but when the second test submits the login form the entire test suite stops and reboots.

Integration Test #1

App = null

module('Acceptance - Page #1',
  setup: ->
    App = startApp()

  teardown: ->
    Ember.run(App, 'destroy')
)

test('page #1 behind authentication', ->
  expect(1)

  visit('/page-1')
  fillIn('input#identification', 'foo@bar.com')
  fillIn('input#password', 'password')
  click('button[type="submit"]')
  andThen(->
    equal(true, true) # This test works fine
  )
)

Integration Test #2

App = null

module('Acceptance - Page #2',
  setup: ->
    App = startApp()

  teardown: ->
    Ember.run(App, 'destroy')
)

test('page #2 behind authentication', ->
  expect(1)

  visit('/page-2')
  fillIn('input#identification', 'foo@bar.com')
  fillIn('input#password', 'password')
  click('button[type="submit"]')
  andThen(->
    equal(true, true) # Never runs, tests start over, infinite loop begins
  )
)

3. EAK api-stubs & Testem

EAK's api-stubs do not seem to be available for Testem, so the "log in" process in these acceptance test when run via the command line/Testem fail.

I attempted setting up sinon.js , but above mentioned issues have prevented me from deciding if it's actually working correctly or not. What is the best way to successfully stub logging in a user with ember-simple-auth? Is it possible to use EAK's api-stubs for Testem?

Answer 1

The example for setting the ephemeral store you're referencing above is outdated (if you're using that it basically has no effect and would default to the localStorage store) - for the new API see the API docs here: http://ember-simple-auth.simplabs.com/ember-simple-auth-api-docs.html#Ember-SimpleAuth-setup .

Maybe fixing that also fixes your 2nd problem (maybe the login form isn't actually displayed in the 2nd test as the user is still logged in anyway as you're using the localStorage store?).

Answer 2

With the help of @marcoow and a few other SO questions and GitHub issues I've been able to resolve all my problems:

1. Devise Authenticator & Ephemeral Storage

I was using an outdated API option in my code. Updating to use the newer API's storeFactory option resolved my session localStorage issue.

#  app/initializers/simple-auth.coffee
if Ember.testing == true
  options = Ember.merge({ storeFactory: 'session-store:ephemeral' }, options)

2. Multiple Acceptance Tests

This turned out to be related to another library I was loading called fastclick . After updating my index file to only load this library in non-test environments, my form submission/infinite loop problems went away.

// app/index.html
<!-- @if tests=false -->
  <script src="/vendor/emberjs-touch/lib/ember-fastclick.js"></script>
<!-- @endif -->

3. EAK api-stubs & Testem

I found other people facing similar issues to me on StackOverflow . Their questions were eventually responded to/resolved which helped me resolve me own issues. In the comments of this GH issue , there is a link to a work-around to this issue. Example here .
