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
