--- Comment #5 from François Gouget fgouget@codeweavers.com 2013-03-17 05:18:12 CDT --- The new plan for this is to get rid of TestLauncher and use winetest.exe directly instead. This will remove code duplication and avoid such issues in the future.
What's needed for that is the ability to package winetest.exe with a single test to not have to shuttle around a bloated binary for every small test.
See bug 33065 - Make it possible to build a winetest executable with a single test.
