[Mono-winforms-list] Testing Visual Properties in MWF

[Ritvik Mayank]

Hi Folks,
              Suresh and I were looking for a Framework that will help
us to test the Visual Properties of MWF on Mono. We have experimented
with the following method. It guides with online instruction which helps
the tester to examine the expected behavior and take the appropriate
step. Attached is the sample code and the screenshot.

Regards,
Ritvik
