List of things we should test

• failures after committing record and before any resources have committed

• failures before committing record.  Does it rollback correctly

• failure after one but not all have prepared

• failure after one but not all have committed

• A mixture of all of the above in one test (to test that the log handles all scenarios at once)

• test log corruption at last record

• test log corruption at any record

• test scenario where not all resources are available at recovery.

• test hot deployment of a resource
