Document necessary unit test changes for async loading

[lanterndev]

When you load translations asynchronously, you have to modify your unit tests to call $httpBackend.expectGET to avoid an unexpected request error. Could you please provide an example of how to update unit tests to do this in the nicest way? Thanks for the continued great work!

Hey,

This is indeed a topic that should be covered in the docs! Thanks for the heads up, will update the docs accordingly but it could take a while since we have to document it in three (the fourth is in the making) languages.

I'll leave this open and close it once it landed in canary branch.

This is how I do it at the moment:

// my angular-translate setup in app.js
app.config(['$translateProvider', function ($translateProvider) {
  $translateProvider.useStorage('translationStorage');

  $translateProvider.useStaticFilesLoader({
    prefix: 'translations/locale-',
    suffix: '.json'
  });
}]);

In every unit-test where I need to flush timeout's I need to add this:

// In this test we need to do flush() so therefore this whenGET() is here.
$httpBackend.whenGET(/^translations/).respond({});

@jenso you could also overwrite $translateProvider behaviour within your test module configuration.

This landed in canary. FINALLY!
