# Recovery Test 1.
# These are the most basic recovery tests. We do individual recovery
# tests for each operation in the access method interface. First we
# create a file and capture the state of the database (i.e., we copy
# it. Then we run a transaction containing a single operation. In
# one test, we abort the transaction and compare the outcome to the
# original copy of the file. In the second test, we restore the
# original copy of the database and then run recovery and compare
# this against the actual database.
