It's that time of year again! Time to get your jam on (I like mine on a bagel).
We love new test contributions, and there's a collection of wiki tutorials and videos to help you contribute them. You don't have to be technical to write tests -- we need manual testcases also which are written in plain English :-)
More interested in submitting your results for tests? We've also got you covered. We have tests for the default applications of ubuntu as well as the images of ubuntu. Download an image and run it on your machine. Try running through some default testcases for ubuntu or your favorite flavor. An image and a pc or laptop is all you need to get started. Happy Jamming!
