lua是一种语法极为灵活、扩展性极强的“胶水语言”, 在使用lua/lua capi时常常会写出一些容易出错的code. 因此,有必要建立以lua vm为基础的unit test帮助程序员及早地发现bug,提高代码的质量。为此,有三件事情需要做。
1 编译配置googletest/googlemock环境

2 编译配置lua5.0
2.1 download src file: https://www.lua.org/ftp/lua-5.0.3.tar.gz
2.2 make
2.3 write testing code:
#include <stdio.h> #include <string.h> extern "C" {///< It is very important to wrap related header files into this cracket, or you will get some error message as below. #include "mylua/lua.h" #include "mylua/lauxlib.h" #include "mylua/lualib.h" } int main(void) { char buff[256] = "print(\"hello world!\n\")"; int error; lua_State* L = lua_open(); /* opens Lua */ luaopen_base(L); /* opens the basic library */ luaopen_table(L); /* opens the table library */ luaopen_io(L); /* opens the I/O library */ luaopen_string(L); /* opens the string lib. */ luaopen_math(L); /* opens the math lib. */ while (fgets(buff, sizeof(buff), stdin) != NULL) { error = luaL_loadbuffer(L, buff, strlen(buff), "line") || lua_pcall(L, 0, 0, 0); if (error) { fprintf(stderr, "%s", lua_tostring(L, -1)); lua_pop(L, 1); /* pop error message from the stack */ } } lua_close(L); return 0; }
2.3 use g++ to build:
g++ test.c -I $LD_HOME/include -L $LD_HOME/lib -llua -llualib -o app
