win32程序代码的单元测试。
请教下面这段代码如何写单元测试桩和驱动呢?
LRESULT CALLBACK About(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam)
{
switch (message)
{
case WM_INITDIALOG:
return TRUE;
case WM_COMMAND:
if (LOWORD(wParam) == IDOK || LOWORD(wParam) == IDCANCEL)
{
EndDialog(hDlg, LOWORD(wParam));
return TRUE;
}
break;
}
return FALSE;
}

这是个回调函数吗?如果是回调函数的话,你应该连它的调用函数一块测的,而且驱动函数要调用是它的调用函数。

其实我就是拿vc6自动生成的“hello,world”,win32的一个程序
,我的实际目的就是想知道win32的函数如何做单元测试!谢谢,能否用这个代码举个例子?谢谢

这个例子实在算不上是代码,因为这些代码都是vc自动生成的框架,因为你的测试本身就是在这个平台上做的,你的测试代码还要依赖这个平台给你生成的一些框架,你能想象出怎么用类中的方法来测试这个类本身吗?你可以在里边写一段自己的代码,然后再针对这段代码进行测试。
leopdong 2006-7-15 14:43
就是因为我对win32编程不是很熟,所以很迷糊。网上很多文章都讲一段很简单的代码,而且都是纯C、C++的,没有哪个文章讲win32代码的,因为我觉得win32他的机制不一样,班主能否讲一段win32代码的如何做单元测试的?
zixuxuwu 2006-7-16 18:35
纯粹的单元测试与机制没有太大的关系,因为它的主体测试对象是一个个的单元,至于具体的单元的确定就要根据不同的情况来确定了。这个得自己来定。

具体测试操作看看这个帖子的介绍
leopdong 2006-8-1 09:15
都是泛泛而谈,这个帖子有win32的代码,为什么斑竹就不能动手写写呢?
理论的东西大家都会说,但是对于实际的测试代码还真的很少看见,所以我对斑竹很有意见了,你既然会,为什么不给我们这些不会的作个实际的例子呢?
