The state of the test-repository is a bit old (approx one year) but you
may have a look into
git://login.openssl.org/openssl
http://www.openssl.org/gitweb.cgi/
When the initial test migrations were performed (2 years ago) I used
cvs2svn-2.1.1
with some setup in cvs2svn-git.options. Since then Geoff Thorpe also
worked a bit on some automatic way to keep the test repo in sync with
the CVS repo but all of this is on hold until the team has come to a
final decision...
