--- Comment #2 from François Gouget fgouget@codeweavers.com --- To run the test through WineTest, upload winetest64-latest.exe and specify the following arguments:
-c -o - -t foo msado15:msado15
Note however that '-o -' requires a WineTest patch: otherwise it will just send the test's output to a file called '-' which the TestBot will not retrieve.

Also if using this trick on a Wine machine and the executable is called 'winetest.exe', Wine will run 'programs/winetest/winetest.exe' instead of your uploaded executable because winetest.exe is a builtin :-( The workaround is to use any name that does not match a Wine builtin.
