Hello Dan!
I'm sure there will always be some tests that are better written directly in CxTest, but I'm going to try to push yawt forward, too. With luck we'll have the two test systems working well together in a month or two.
YAWT looks interesting, I also had a look to AutoHotKey, and its language seems to solve some of the problems we have with CxTest scripts (double click, better support for menus, better conditioning). It also introduces hard dependency on Windows and Wine (CxTest can test also X11 apps), which is problematic in case of i.e. CrossOver installation (X11 based app).
We try to write some tests in YAWT and see how it works. Regarding Direct3D testing framework, we try both YAWT and CxTest and use whatever is easier to use for that purpose. Important thing is that Stefan does not create new server side (PHP code and some things around), we should just extend current implementation with ability to generate 2D graphs, then we have everything in one place (Wine make test results, Direct3d performance results) instead of several web pages with pieces of information.
