TestDrive Virtualizes Brand-New Ubuntu Builds for Easy Testing
Ubuntu: Want to try out the latest build of the next Ubuntu release with almost no hassle at all? TestDrive is a one-shot tool that downloads, virtualizes, and keeps daily Ubuntu builds up to date.
TestDrive runs from the command line, but you literally enter only one number to make it work. Run it from your Applications/System Tools menu, and a terminal prompt asks you to pick which daily build of Ubuntu you want to install. Enter your number, hit return, and TestDrive gets to work downloading the latest ISO, turning it into a virtual machine, and then, if you have VirtualBox or KVM installed, launching it immediately.
