将 pod 'MockFive' 添加到 Podfile 中，或将 MockFive.swift 从 MockFive 文件夹拖到您的项目中。
使您的模拟对象符合 Mock 协议，并在结构体或类中的任何地方添加 let mockFiveLock = lock()。现在您可以使用 mock() 了！在函数体中调用 mock() 会在 myMockObject.invocations 中记录其调用，并在运行时实现替代实现。
使用 MockFive 允许对象报告它们被调用的哪些函数，并允许在运行时进行方法存根。由于 MockFive 使用反射生成其消息，mock() 方法保证了测试字符串始终与生产代码匹配。《Mock》协议可以被结构体模拟和类模拟采用。
