Is there a reason we don't have unit tests for the message_box module?

[osinjoku]

Not worth it with the heavy use of the Win32 API. The integration cover the cases quite well.

[LiawChungYao]

Shouldn't we use the automodule like the other files or is there some custom content added to this page?

[osinjoku]

automodule is there in the API section. I have added extra docs to help the user.
