在我的应用程序中，我成功使用了Firebase，在AppDelegate中我进行了设置：
原文链接：https://www.f2er.com/swift/320214.html// ### Initialize Firebase FIRApp.configure()
现在我对相关目标进行一些单元测试，当我启动它时，我得到错误：
2017-04-14 14:53:22.351 MyProject[28753] <Error> [Firebase/Core][I-COR000004] App with name __FIRAPP_DEFAULT does not exist. 2017-04-14 14:53:22.354 MyProject[28753] <Error> [Firebase/Messaging][I-IID001000] Firebase is not set up correctly.

版本：
Firebase/Core (3.16.0) Firebase/Messagging (3.16.0)
任何建议？
