I think a option to test a single mod/group of mods would be nice. would do the run system for a world but not actully make a world. that way if (like me) your having problems with the game (aka keeps crashing on map gen) you can test some mods not only for any clashes but if a mod no longer works or need updating

cata\_test takes mod arguments, so you can do  
`./tests/cata_test --mods=<mod1, mod2>`  
to run the standard test suite on a world that has mod1 and mod2 in its mod list.

You need to compile it. Use MSYS if you are on Windows.
