Today I saw two similar projects related to OpenGL: [1]:

It seems be having win32 port also. [2]: > Piglit is a collection of automated tests for OpenGL implementations. > > The goal of Piglit is to help improve the quality of open source OpenGL > drivers by providing developers with a simple means to perform > regression tests. > > Current status is that the framework is working (though rough at the > edges).

Then there is PerceptualDiff utility I found some time ago [3]. Guessed, could it also usefull for finding visual regressions of Wine? Probably not, as it seems to be used for testing video codecs (but I may be wrong): > PerceptualDiff is an image comparison utility that makes use of a > computational model of the human visual system to compare two images. > > So why would I use a program to tell me if two images are similar if I > can tell the difference myself by eyeballing it? > > Well the utility of this program really shines in the context of QA of > rendering algorithms. > > During regression testing of a renderer, hundreds of images are > generated from an older version of the renderer and are compared with a > newer version of the renderer.
