Error: Unexpected request: GET http://... using ng-html2js

I'm getting this error when I'm unit testing a directive. Instead to use httpBackEnd for retrieving the template. I' using ng-html2js on Karma config.

Error: Unexpected request: GET http://

My point is that when I'm rendering data-mylist directive I'm getting the error above because in the controller liked to this directive there's a service using an $http call on the loading of the directive.

Then I'm wondering. ng-html2js is being used just to load the template and then I have to use httpbackend to deal with this specific $http call.

Or

Should the ng-html2js already give me the template with all dynamic data rendered?

Unit test

ddescribe('Directive', function () {

  // load the directive's module
  beforeEach(module('App'));
  beforeEach(module('Templates')); // The external template file referenced by templateUrl

  var element, scope, _Dataservice_;

  beforeEach(inject(function ($rootScope, Dataservice) {
    scope = $rootScope.$new();
    _Dataservice_ = Dataservice;
  }));

  it('Should show message for no data found', inject(function ($compile) {

    spyOn(_Dataservice_, 'dataList').andReturn(null); //spy the dataList function
    //_Dataservice_.dataList= null;
    element = angular.element('<div data-mylist></div>');
    element = $compile(element)(scope);
    scope.$digest();
    expect(element.find('mylistClass').length).toBe(1);

  }));

});

Karma config(part of):

module.exports = function(config) {
  config.set({
preprocessors: {
    'app/src/**/views/**/*.html': ['ng-html2js']
},

ngHtml2JsPreprocessor: {

    //stripPrefix: 'app/',
    //or define a custom transform function
    cacheIdFromPath: function(filepath) {
        return filepath.match(/src\/.*\/views\/.*\.html/)[0];
    },

    // setting this option will create only a single module that contains templates
    // from all the files, so you can load them all with module('foo')
    moduleName: 'Templates'
},

  });
};
