I'm a complete n00b at this and am eternally grateful for any assistance.

The goal is to automated round robin lead assignments.  I’ve installed the Round Robin Record Assignment app which is designed for Cases, but as others have said here and elsewhere, it needs some modification to make it work for Leads.  I’ve followed the instructions to create the triggers leadOwnerUpdate and leadRoundRobin based on what was built in for Cases (I would link to the page where I got the leadRoundRobin code, but I can’t seem to find it right now – it’s basically using Lead instead of Case in these new triggers).  I also created a class called TestMethodCls4 which is based on what’s included for the package for testing Cases, but it’s saying I’ve only got 66% test coverage when I try to deploy the two new triggers and class from the Sandbox to the Enterprise account.

Can anyone provide any assistance as to how I should update my test class to get at least 9% more coverage?  I've been up almost the entire night working on this and researching what I could find online, so this is a last resort.  Thank you in advance!
