cxtest has already impressive infratructure (installation, creation of
clean environment) and nice scripting. However, it requires Metacity WM
I'm personally using AutoHotkey(http://www.autohotkey.com) as an
automatic testing framework backend. It's a Windows application, so it
can be run through Wine itself and it's sandboxed from X11.
I can imagine Winebot packages to be easily converted to an automatic
testing engine. Winebot actually covers automated installation and
creation of clean independent environment.
Running applications with different log levels, tracing output,
comparing screenshots with different levels of fuzzy comparaion
- it's not faraway.
AFAIK cxtest has the better functionality now.
