Angular services not being defined in beforeEach in Karma - angularjs

Question

I have an Angular Application using Jasmine and Karma for testing.
This is my testing class:
var data = require('./user.mock.js');
describe('Service: UserService', function () {
var ServerUrl;
var httpBackend;
var userService;
beforeEach(angular.mock.module('myModule'));
beforeEach(angular.mock.inject(function (_userService_, $httpBackend, _ServerUrl_) {
userService = _userService_;
httpBackend = $httpBackend;
ServerUrl = _ServerUrl_;
}));
describe('when get the active users from backend', function () {
// given
beforeEach(function () {
httpBackend
.whenGET(ServerUrl + '/users')
.respond(angular.copy(data.activeUsers));
});
it('should return the list of active users', function () {
var expectedUsers = angular.copy(data.activeUsers);
expectedUsers[0].profilePicture = ServerUrl + '/pictures/' + expectedUsers[0].id + '/small/show';
expectedUsers[1].profilePicture = ServerUrl + '/pictures/' + expectedUsers[1].id + '/small/show';
userService
.listUsers()
.then(function(users) {
expect(users).toEqual(expectedUsers);
});
httpBackend.flush();
});
});
And this is my karma conf:
// Karma configuration
// Generated on Tue May 19 2015 15:02:17 GMT+0100 (WEST)
module.exports = function(config) {
config.set({

};
When I run karma test from the command line, the services injected do not get recognized. I am suspecting that the inject function is not being called in the beforeEach method, but I am not sure. I am getting undefined in the tests, as if the variable never got any value.

Can you guys help me?

Answer 1

Two things I remember:
The order of the JS files has to be right in the config files
The usage seems grossly right and is this. Just check if this makes a
difference :
beforeEach(inject(function($controller, $rootScope, _myService_){
scope = $rootScope.$new();
myServiceSvc = _myService_;
firstCtrl = $controller("firstCtrl",{
$scope: scope,
myService: myServiceSvc
});
}));
karma.conf
files: [
'index.html',
'lib/angular.min.js',
'lib/angular-ui-router.min.js',
'lib/angular-mocks/angular-mocks.js',
'lib/app.js',
'tests/controller/basics.js'
],

In the end it just a stupid error (as most of them are).
Using git bisect, I was able to find the commit where the tests stopped working.
In that commit, I saw that I added the ng-jwplayer dependency to the project. The library requires a javascript call before it the html file.
'https://content.jwplatform.com/libraries/XXXXXX.js',
That url was missing in the karma.conf files array. It was generating an error:
files: [
'http://maps.googleapis.com/maps/api/js?sensor=false&language=en',
'https://content.jwplatform.com/libraries/XXXXXX.js',

'bower_components/angular-ui-map/ui-map.js',
'bower_components/bootstrap-sass/assets/javascripts/bootstrap.js',
'bower_components/bootstrap-select/dist/js/bootstrap-select.js',
'bower_components/event-signal/dist/event-signal.min.js',

'bower_components/angularUtils-pagination/dirPagination.js',
// endbower
'src/app/**/*.js',
'src/app/views/**/*.html',
'src/test/**/*.js'
],
With the url included, the files work well. This was another case of misleading error message.
