在简单的Jasmine测试中注入$ log服务

Question

是的，我是Angular和Jasmine的新手，我无法弄清楚如何为我的测试注入一个模拟$ log。这是测试：

(function () {
    'use strict';

    describe('basic test', function(){
        it('should just work', function(){
            var $log;

            beforeEach(inject(function(_$log_){
                $log = _$log_;
            }));

            $log.info('it worked!');
            expect($log.info.logs).toContain(['it worked!']);
        });
    });

}())

这在注入行上失败并出现错误：

TypeError: Cannot set property 'typeName' of undefined

我错过了什么？

这是怎么回事：

describe('basic test', function(){
    var log;
    beforeEach(inject(function(_$log_){
        log = _$log_;
    }));

    it('should just work', function(){
        log.info('it worked!');
        expect(log.info.logs).toContain(['it worked!']);
    });
});
