At the Mercury Interactive Worldwide Conference in 2002, I did a presentation on using dynamic GUI maps with WinRunner. The presentation (in PDF format) can be accessed here.
On a less formal basis, I have created the following presentations on various topics somewhat related to test automation. These were given to a group of people with whom I worked with in 2008. The PDF versions of the presentations are available.
Sticky Minds published an article on July 22, 2008 about data-driven test automation. The article can be accessed here.
In 2003 I wrote an article on test automation architectures. I didn't do anything more with it. The article (in PDF format) can be accessed here.
