mysql tests for XA during recovery

[Zardosht Kasheff]

Hello all,

Are there any XA tests in the MySQL test suite that execute the
functions one would expect to see during recovery. Namely, I am
looking for tests that execute:
 - handlerton->recover
 - handlerton->commit_by_xid
 - handlerton->rollback_by_xid

I see xa.test, but I don't think that executes the functions mentioned above.

Thanks
