Testing an AngularJS factory with Karma (Jasmine)

Question

I\'m struggling with testing an AngularJS factory using Karma + Jasmine.

I am unable to inject my factory to OfficerValidationService variable.

Answer 1

To add to martynas' answer, here is a simplified version:

module() is the shorthand of angular.mock.module
inject() is the shorthand of angular.mock.inject (same as $injector)

'use strict';

(function() {
  describe('OfficerValidationService Spec', function() {
    var OfficerValidationService;

    beforeEach(module('darthvader'));
    beforeEach(inject(function (OfficerValidationService) {
      OfficerValidationService = OfficerValidationService;
    }));

     it('OfficerValidationService should exist', function() {
        expect(OfficerValidationService).toBeTruthy();
    });


  });
}());

Answer 2

You need to call angular.injector:

'use strict';

(function() {
  describe('OfficerValidationService Spec', function() {

    var OfficerValidationService;

    beforeEach(function() {
      angular.module('darthvader');
    });

    beforeEach(inject(function() {
      var $injector = angular.injector(['darthvader']);
      OfficerValidationService = $injector.get('OfficerValidationService');
    }));

    it('is very true', function(){
      var output = OfficerValidationService.something();
      expect(output).toBeTruthy();
    });

  });
}());
