Below is a test demo for your service:

describe("UserService", function() {
  var service;
  var $rootScope;
  var $httpBackend;

  var dataMock = ["John", "Albert", "Mary"];

  beforeEach(module('app'));

  beforeEach(inject(function($injector) {
    $rootScope = $injector.get('$rootScope');
    $httpBackend = $injector.get('$httpBackend');
    service = $injector.get('UserService');
  }));

  afterEach(function() {
    $httpBackend.verifyNoOutstandingExpectation();
    $httpBackend.verifyNoOutstandingRequest();
  });

  it('should fetch 3 users', function() {
    $httpBackend.when('GET', 'https://api.github.com/users').respond(dataMock);
    service.GetAll().then(function(users) {
      expect(users.length).toBe(3);
      expect(users).toEqual(dataMock);
    });
    $httpBackend.flush();
  });

  it('should return error', function() {
    $httpBackend.when('GET', 'https://api.github.com/users').respond(403);
    service.GetAll().then(function(error) {
      expect(error.success).toBe(false);
      expect(error.message).toEqual('Error getting all users');
    });
    $httpBackend.flush();
  });
});
