Answer 1

I use this pattern.

• ApplicationModule set regular angular-translate config.
• test code load 'testModule' instead of 'applicationModule'

// application module .js 
(function() {
  'use strict'; 
  
  angular
   .module('applicationModule', [
    'ngAnimate',
    'ngResource',
    'ui.router',
    'pascalprecht.translate'
  ])
  .config(['$stateProvider', '$urlRouterProvider', '$translateProvider', '$translatePartialLoaderProvider', config]);

  function config($stateProvider, $urlRouterProvider, $translateProvider, $translatePartialLoaderProvider) {
    // set routing ... 
        
    $translateProvider.useStaticFilesLoader({
      prefix: 'i18n/locale-',
      suffix: '.json'
    });

    $translateProvider.useMessageFormatInterpolation();
    $translateProvider.fallbackLanguage(['en']);
    $translateProvider
    .registerAvailableLanguageKeys(['en', 'ko'], {
      'en_US': 'en',
      'ko_KR': 'ko'
    })
    .determinePreferredLanguage(navigator.browserLanguage);

            
    $translateProvider.addInterpolation('$translateMessageFormatInterpolation');    
    $translateProvider.useSanitizeValueStrategy('escaped');
  }

})();

// test.module.js
(function() {
  'use strict';

  angular
    .module('testModule', ['applicationModule'])
    .config(['$translateProvider', '$translatePartialLoaderProvider', config])
    .run(['$httpBackend', run]);

  function config($translateProvider, $translatePartialLoaderProvider) {
    $translateProvider.useLoader('$translatePartialLoader', {
        urlTemplate: 'i18n/locale-en.json'
    });
    $translatePartialLoaderProvider.addPart('applicationModule');
  }

  function run($httpBackend) {
    $httpBackend.when('GET', 'i18n/locale-en.json').respond(200);
  }

})();


// someDirective.spec.js
describe("a3Dashboard", function() {
    beforeEach(module("testModule"))

    var element, $scope;
    beforeEach(inject(function($compile, $rootScope) {
        $scope = $rootScope;
        element = angular.element("
{{2 + 2}}
");
        $compile(element)($rootScope)
    }))

    it('should equal 4', function() {
      $scope.$digest();
      expect(element.html()).toBe("4");
    })

})
