Stress Testing with git

I have an application that monitors git traffic of all kinds. The problem is is that I only am prepared to handle certain events like commits, branch creation/deletion, tag creation/deletion, and notes, but there are a lot of other funky situations git can get itself into.

Is there anything that anyone knows of that is like a thorough test of a large variety of git commit interactions that one could use to stress test an application meant to monitor git traffic?
