Unit Test Karma - Dependencies

I'm trying to test a service of my Angular app with Karma, but I got an error I can't solve : "[$injector:unpr] Unknown provider: $issueProvider <- $issue"

Here is the beginning of the service I want to test :

angular.module("aq.kiosk.api.issue.services")

.service("$issue", ["$q", "$log", "IssueResource", "IssueModel", "$user", "Config", "DateUtils", "$kioskCache", "$filter", "$modal", "$loadingTasks", "$bridge",
    function ($q, $log, IssueResource, IssueModel, $user, Config, DateUtils, $kioskCache, $filter, $modal, $loadingTasks, $bridge) {

        this.get = function (issueId) {
            var defered = $q.defer();

            var issueCache = $kioskCache.getGlobalMap(issueId);

            if (angular.isDefined(issueCache)) {
                defered.resolve(issueCache);
            }
            else {
                var data = {
                    issueId: issueId
                };
                IssueResource.get({}, data,
                    function (result) {
                        var formattedIssue = undefined;
                        if (result && result.data && result.data.issue) {
                            formattedIssue = _getNormalizedIssue(result.data.issue);
                            formattedIssue = new IssueModel(formattedIssue);

                            _checkIssueDownloaded(formattedIssue);

                            $kioskCache.setGlobalMap(formattedIssue);

                            defered.resolve(formattedIssue);
                        }
                        else {
                            defered.resolve(undefined)
                        }
                    },
                    function (response) {
                        defered.reject(response)
                    }
                );
            }
            return defered.promise;
        };

And here is my test file :

describe('API Account Service', function () {

// Inject the module and the service.
var Config, $account, $httpBackend, IssueModel, $issue, $kioskCache;
beforeEach(module("aq.kiosk.api.config"));
beforeEach(module("aq.kiosk.api.account.services"));
beforeEach(module("aq.kiosk.api.issue.services"));
beforeEach(module("aq.kiosk.api.cache"));
beforeEach(inject(function (_Config_, _$httpBackend_, _$issue_, _$account_, _IssueModel_, _$kioskCache_ ) {
    Config = _Config_;
    $account = _$account_;
    $issue = _$issue_;
    $httpBackend = _$httpBackend_;
    IssueModel = _IssueModel_;
    $kioskCache = _$kioskCache_;
}));

describe('#get()', function () {
    it("should be defined", function () {
        $issue.get.should.be.ok;
    });
});

});

I pretty sure my mistake come from the inject, but I don't know what exactly. (And I think I have the good files in my karma.conf.js)

Any idea ? Thank you very much
