AngularJS unit tests for module.config

In our project, we use requirejs with angularjs. We have a main application module (app) and module for all services (app-services), module for all controllers (app-controllers), module for all filters (app-filters). Modules app-controllers, app-services etc.. are added as dependencies to main app module.

main application module

var mainAppModule = angular.module('app', [
        'ngResource',
        'ngSanitize',
        'app.controllers',
        'app.directives',
        'app.services',
        'app.filters',
        'app.routes'
    ]);

mainAppModule.run(['$location', '$rootScope', function ($location, $rootScope) {
    $rootScope.sayHello = function(name) {
        console.log("Hello" + name);
    }
}]);

app-services module

define(['angular'], function (angular) {

    var module =  angular.module('app.services', []);

    module.config(['$provide',function($provide){

        module._service = module.service;
        module._factory = module.factory;
        module._value = module.value;

        module.service = function( name, constructor ) {

            $provide.service( name, constructor );
            return( this );

        };

        module.factory = function( name, factory ) {

            $provide.factory( name, factory );
            return( this );

        };

        module.value = function( name, value ) {

            $provide.value( name, value );
            return( this );

        };
    }]);


    return module;  
});

My questions are

a) how can write unit tests (jasmine/karma) for mainAppModule.run ?

b) how can write unit tests for app-services.config?

Any help is greatly appreciated.
