But sometimes we need to change the env to finish some unit test. The following way just like a hack but it is ok to unit test: private void setNewEnviron ...

It'll be a challenge to get the expected result as they are changing with time, then it's time to use the Mock tool. today I meet the same issue, I need to test one method timeFormat(), this method is to form ...

今天在stackoverflow上面看到一个帖子讨论说关于提高数组效率的问题,看了下他的问题,是关于一个四维数组的效率问题,四维数组类似这样子: ushort[, , ,] map = new ushort[3000, 3000, 3, 3]; 暂且先不管为啥要搞一个四维数组(毕竟四维已经超出了人的立体思维想象了-_-),我随手写了一个测试类来测试,但是发现了一个更有意思的现象,数组声明方式不同会导致初始化的效率极大区别: 声明方式一: int [][][][] map = new int[3000][3000][3][3]; 声明方式二: int [][][][] map2 = new in ...
以此作为笔记,记录一些小碎片,省得以后再去找。 1. 如何读取和当前class位于同一目录下的文件,也可以是其他相对路径: xml在随意某个包路径下: String s_xmlpath="com/spf/web/ext/hotspot/hotspotxml/hotspot.xml"; ClassLoader classLoade ...
