描述

I've found that many Closure externs are out of date for Jasmine. Specifically, I see:

Many custom matcher types are missing, including:
- CustomMatcherFactories
- MatchersUtil
- CustomEqualityTester
- CustomMatcher
Jasmine's pretty print utility is missing (jasmine.pp())
Most matcher functions (toBe(), toEqual(), etc.) accept an optional string to use as an error message if the expectation fails. This is also missing.
Likely others...

Without these types, custom matchers are basically impossible. Would be great to see these types updated.

贡献者指南

研究方向: 通过比较当前的extern文件与Jasmine API文档，找出缺失的Jasmine extern类型。添加缺少的类型定义（CustomMatcherFactories、MatchersUtil、CustomEqualityTester、CustomMatcher），并更新现有的匹配器函数以包含可选的message参数。参考https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/jasmine/index.d.ts中的extern文件作为指导。
