luaunit的使用

github的地址：

https://github.com/bluebird75/luaunit

使用说明文档：

http://luaunit.readthedocs.org/en/latest/

使用方法：

测试命令：lua.exe <测试用例文件：testcase.lua> -v(显示每一项测试结果)

UT目标文件：testlib.lua

 1 function add(v1,v2)
 2     -- add positive numbers
 3     -- return 0 if any of the numbers are 0
 4     -- error if any of the two numbers are negative
 5     if v1 < 0 or v2 < 0 then
 6         error('Can only add positive or null numbers, received '..v1..' and '..v2)
 7     end
 8     if v1 == 0 or v2 == 0 then
 9         return 0
10     end
11     return v1+v2
12 end
