CMocka

CMocka 是一个优雅的 C 单元测试框架，支持模拟对象。它只需要标准的 C 库，适用于各种计算平台（包括嵌入式）和不同的编译器。它有一个关于使用模拟测试， API 文档和各种示例的教程 。

void null_test_success (void ** state) {}

void null_test_fail (void ** state)

/* These functions will be used to initialize
   and clean resources up after each test run */
int setup (void ** state)
{
    return 0;
}

int teardown (void ** state)
{
    return 0;
}

    };

    /* If setup and teardown functions are not
       needed, then NULL may be passed instead */
