Say that MSYS can be installed for testing. Anyway, I would
like to separate test description and the script running it.

Without output data verification it is almos useless in my opinion.
I have 2 examples in my mind I recently saw:
- new bug introduced in v.to.rast (last line segment not rasterized)
- bug in v.in.ascii on Windows (missing header file -> wrong output)

That is why I suggested a small mapset with etalon output data
which can be used for verification of test output.
