Re: [TFUI] Digest Number 225

Phlip -

Building a unit test framework into a legacy GUI app
is a hard problem (especially using MFC). Your
approach is excellent: minimum code changes, minimum
effort to build tests.

When you make the dialog not WS_VISIBLE, you have to
add code to show() it. When I test GUI objects, I
generally don't care whether they are visible or not,
as long as I don't have to interact with them.
Besides, the visible GUI operations make it look like
I'm actually working. :)

What is the purpose of capturing the window as a
bitmap? I would comment that trying to unit test the
exact pixel output of a GUI is very expensive, and
usually unnecessary.
