Another approach is to capture bugs in the form of test cases for a
test suite. That way, as long as you rerun the test suite
periodically, you can make sure that the bugs never return.
For those who don't know, I've been developing a framework for OpenGL
testing, and the first alpha release (with just a few demonstration
tests to show how it works) is now on mesa3d.org:
http://www.mesa3d.org/glean/
I've applied lessons learned by both the OpenGL conformance-testing
team and the high-end graphics group while I was at SGI, so I think
the basic design is sound. However, there's plenty of opportunity to
add to the suite, and I encourage everyone to add test cases for
whatever features are most important to you. You can send code to
[EMAIL PROTECTED] .
By the way, Jim Bushnell volunteered to help port the suite to Windows
starting next week. Once that's done, maybe I'll hold a contest. How
about US$50 for each of the three best new additions to the suite? :-)
