How to test function in AngularJS service with mock data

How to create Jasmine unit test for one function in AngularJS service provider that has its own dependencies. I want to create mock data for myObject and test function getObjectShape() with that mock data. How to achieve that?

    (function () {
    'use strict';
    angular.module('objectShapes')
            .provider('shapesResolver', shapesResolver);

        function shapesResolver() {

            this.$get = function () {
                return resolver;
            };

            function resolver(myObject) {

                var service = {
                    getObjectShape: getObjectShape
                };

                function getObjectShape() {
                    return myObject.Shape;
                }
            }
        }
})();
