c++ - MFC 应用程序的测试框架

Question

我正在为我们的 MFC 应用程序寻找一个测试框架。看了很多框架比较的Q&A

• Comparison of c++ unit test frameworks
• Unit testing for C++ code - Tools and methodology
• C++ unit testing framework

但对于我的真正目的，构建可靠的 MFC 应用程序，我看不出有什么不同。如果任何对这些框架有经验的人都可以阐明一些信息，我将不胜感激。

Answer 1

我已经使用了其中的一些(我主要使用 junit)。这些都是非常劳动密集型的——没有办法自动找到并运行测试。你可以考虑使用 nunit和 c++/cli

这是 c++/cli 测试示例之一:
