How to mock angular translate filter in unit tests for directives

Question

In my directive templates, I need to use the angular translate filter as such:

Answer 1

This is working for me. But of course you should set mockTraslateFilter value to function bewfore you will use it in another funciton.

var mockTranslateFilter;

beforeEach(function() {
  mockTranslateFilter = function(value) {
    return value;
  };
  module(function($provide) {
    $provide.value('translateFilter', mockTranslateFilter);
  });
});

even shorter, if you use ES6:

    beforeEach(angular.mock.module(progressBarComponent, ($provide) =>      {
        $provide.value('translateFilter', (v) => v);
    }));
