Issues with lodash when trying to test using bard and mocha?

So I'm coming up with an issue when developing tests for some AngularJS factories.

I have one that uses lodash. Whenever I try to run the test spec runner, this is what I get:

This is how my code looks in the places that use lodash, or specifically, the ngLodash directive.

In file chart-service.js

 angular
    .module('app.core')
    .factory('ChartService', ChartService);

ChartService.inject = ['DataService', 'QueryService', 'lodash', '$q', '$log', 'APPSETTINGS', 'CacheService', '$timeout'];

function ChartService(DataService, QueryService, lodash, $q, $log, APPSETTINGS, CacheService, $timeout) {

In a different file (app.module.js)

 angular.module('app', [
    // App Modules
    'settings',
    'app.core',
    'app.navigation',
    'app.widgets',
    'app.workspace',
    'app.dslegend',
    'app.custompage',

    // Common Modules
    'common.utilities',
    'common.exception',

    'ngLodash'

]);

In the app.core module:

 angular
    .module('app.core', [
        //'ngAnimate',
        'common.exception',
        'common.logger',
        'ui.router',
        'ngStorage',
        'xeditable'



    ]);
