If you've been following open source development for the last little while, you may have heard of Travis, the free continuous integration service for open source projects. I've been interested in trying it out, but I haven't had a project I thought was suitable for testing with it.
Until now! As luck would have it, the most recent UpThing installment added a PHPUnit-based functional test. This means that I've got something I can send to Travis. :)
