测试用例

/* test case : test.c */#include#include"assert_self.h"  int main(int argc, char* argv[]){    switch(argc)    {        case 2:            ASSERT1(atoi(argv[1]));            break;        default:            printf("ARG ACCEPT 1\n");            break;    }    exit(0);}

软件Bug定位，很多时候，比如利用Assert宏，可以把48小时的调试大餐压缩成1口可以吃掉的饭后甜点，每个软件小组都在重新演化，过去的经验总是得不到很好的传承，这就是我们！
