tests for git-p4

I'm planning to write a "p4-fast-export" that will facilitate using
Bazaar on projects maintained in Perforce.  I'd like to reuse code
from git-p4 since it appears to have much of the functionality I want.
 In fact, the main reason I can't just use git-p4 today is that it
does too much: it pushes the Perforce fast-export representation
directly into Git.  I'm going to work on covering the existing
functionality in tests before I start modifying the code, and I could
try to write those tests such that they'll be useful to the Git
project as well.

Would my tests be of interest to git-p4's authors? Is there any existing test framework for git-p4 that I missed?
