Here lives an experimental bot that does this: Commitfest → Github → ( Travis, AppVeyor ). You can find a report for the current CF, the next CF or individual patch authors.
Announcing some new features: result links now take you directly to build logs, testing is now done on multiple operating systems, and new patches should be picked up a lot more quickly than before.
