Code Coverage has been out for a little while now and it is brand new functionality that isn't just an incremental improvement on existing features from WDSc etc.
In order to help people get comfortable with these new feature a new lab has been added to the set of Hands-On labs so that anyone can play with this and see how to apply this within the context of their own shop.
The entire set of labs is available at http://ibm.biz/rdi_labs and the 10th lab is the brand new one. You will need at least RDi 9.5 to try this and IBM supplies the IBM i backend. Lab #1 will show you how to get a userid and connect to this demo IBM i, and then you can jump right to the Lab #10 if you like.
