Micheus and gg, both you guys know how to use git.
Just create a remote and fetch the branch you want to test

I sometimes also help dev for a project called mypaint, and their users pull git branches for testing without having any coding skills! Of course wings is a tad bit more complicated to build. But once the dev/git environment is setup, it's dead easy to try the latest version of wings any dev is producing.
