Mockito使用案例

需求

接入facebook第三方登录
官方接口文档
https://developers.facebook.com/docs/graph-api/reference
官方接口调试工具
https://developers.facebook.com/tools/explorer/

背景

由于国内无法连接facebook，需要借助VPN，而我使用的VPN又只支持全局模式，使用的话就无法再访问大多数的国内网站，而一个第三方登录接口既要访问外网，又需要访问内网，无法同时兼顾，因此给程序调试带来非常大的困难

解决

1、首先连接VPN，仅对所需要接入的facebook接口做单元测试，确保程序调用facebook接口这一步没有问题
2、利用mockito Mock掉第三方登录接口中需要调用facebook的两个步骤，然后在需要连接VPN调试的地方做断点就很好做整体测试了
