i18.base.spec.js

// Global jasmine hook to prevent errors when attempt to
// download a localization .json file in test environment.
// Here we are resetting the translate provider to a
// safe state.
// If a test needs to assert for localized texts,
// the test author is free to setup the translate provider
// on isolation by overriding its settings.
// This wont affect other tests because once the test execution
// exits, the translate provider is reset once again to
// a safe state.
// The error we get if we do not add this global hook is:

// Error: Unexpected request: GET /locale.en.json
// No more request expected

beforeEach(function() {
  var DEFAULT_LANG = 'en';
  var DEFAULT_TRANSLATIONS = {};
  var MODULE_NAME = 'myapp.i18n'; // UPDATE ACCORDINGLY

  module(MODULE_NAME, function config($translateProvider) {
    $translateProvider.translations(DEFAULT_LANG, DEFAULT_TRANSLATIONS);
    $translateProvider.preferredLanguage(DEFAULT_LANG);
  });
});

@emiaj Issue was when setting up directive unit tests - this had to be done in a particular way. Otherwise, we would get the "multiple directives" error. You need to move the directive setup code before the mock data and call an additional $digest after the mock data setup:

// Wrong way
beforeEach(inject(function($rootScope, $compile)
{
  ... mock data ...
  confirmMessage = angular.element('<confirm-message/>');
  $compile(confirmMessage)(scope);
  scope.$digest();
}));

// Correct way: we need the following workaround
beforeEach(inject(function($rootScope, $compile)
{
  confirmMessage = angular.element('<confirm-message/>');
  $compile(confirmMessage)(scope);
  scope.$digest();
  ... mock data ...
  scope.$digest();
}));

@emiaj, how are you calling this "global hook" in Karma?

I'm running a Yeoman-scaffolded project that sources everything in tests/mock/**/*.js before running the actual specs. I've tried adding your snippet above into a mock module and adding it as a dependency to each spec, to no avail.
