该类可以实现自动类型判断模拟一些比较合理的数据，比如对于时间字段对于昵称字段对于头像字段的假数据自动填充。
在服务器接口还没出来的情况，要模拟模型数据填充，最快的方法当然是我这个测试工具类了.
用法:
if (BuildConfig.DEBUG) {
return TestUtils.createModeListAndFillField(DetailPersonModel.class);
}
//或者
TestUtils.createModelAndFillField(model.class);
有一些不严谨，比如对类型的判断，不够我自己够用，各位自己遇到问题的欢迎改改，我再提交一下。

日志开关工具类用于解决Log在编译后一直打印问题优化性能也方便控制.使用时把所有的Log.替换为Prt. 然后把导入包的也批量替换一下就完成了优化。怎么替换需要技巧的。
