如何使用jasmine为AngularJs的会话创建模拟会话

Question

在AngularJs中，我必须使用茉莉花来测试过滤器。我在控制器中的session中设置了studentNameFormat。我有一个像这样的过滤器：

angular.module('course.filters').filter('studentName',['Session',
    function (Session) {
    return function (student) {
        var format = Session.getState().studentNameFormat;

        if(format == '0') {
            return   student.firstName + " " + student.lastName;
        }
       else{
            return student.lastName + student.firstName;
        }
    };
}]);

为了测试Jasmine中的方法，我需要将Session对象传递给该方法。如何创建模拟会话变量？

I have test filter like:

describe('studentName', function () {

    'use strict';

        var $filter;
        var student;
        var session;
        beforeEach(function () {
            module('course.filters');

            inject(function (_$filter_, _Session_) {

                $filter = _$filter_;
                session = _Session_;

            });
            patient = {
                "firstName": "John",
                "lastName": "Doe"
            }

            session.setState({
               studentNameFormat: 1
            });

        });

        it('return full lastName full FirstName if given 1', function () {
            console.log(patient);
            var studentFilter = $filter('studentName');

            expect(studentFilter (student)).toEqual("Doe John");

        });

它给了我错误sessionProvider未定义。 错误：[$ injector：unpr]未知提供者：SessionProvider＆lt; - Session＆lt; - studentFilter
