Jmockdata

Jmockdta是一款實現模擬java類型或對象的實例化并隨機初始化對象的數據的工具框架。單元測試的利器。The plug-in of Jmockdata what through random algorithm mock java data.Jmockdata插件通過隨機算法模擬Java數據.

具體介紹和用法可以參考如下：

模擬數據入口方法 JMockData.mock(JmockDataWrapper)被模擬數據必須繼承JmockDataWrapper經過它的包裝被模擬的數據最好是plain bean,只提供getter,setter,has,is方法的才可以被模擬

框架默認實現了40個元數據類型的數據模擬器包括：

short.class,Short.class,short[].class,Short[].class, int.class,Integer.class,int[].class,Integer[].class, long.class,Long.class,long[].class,Long[].class, float.class,Float.class,float[].class,Float[].class, double.class,Double.class,double[].class,Double[].class, boolean.class,Boolean.class,boolean[].class,Boolean[].class, char.class,Character.class,char[].class,Character[].class, String.class,String[].class, BigDecimal.class,BigDecimal[].class, BigInteger.class,BigInteger[].class, Date.class,Date[].class

通過對以上基本元數據類型的模擬實現，能夠進一步實現BEAN，LIST,SET,ARRAY等結構的模擬。

可以通過JmockDataContext 獲取模擬過程的所有上下文信息，甚至可以打印整個模擬類型樹可以通過JMockDataManager 注冊模擬數據類型，重寫模擬數據算法，注冊模擬數據類攔截器等可以通過實現MockData來實現一個模擬數據類型可以通過實現JmockDataTemplate，或者繼承JmockDataTemplateDefault來重寫模擬數據算法可以通過實現JmockDataInterceptor來實現一個攔截器具體示例實踐請參考https://github.com/jsonzou/jmockdata-demo有問題或者對本框架有新的想法，請聯系我，作者：jsonzou
