# TEST Per-operation recovery tests for non-duplicate, non-split
|
||||
# TEST messages. Makes sure that we exercise redo, undo, and do-nothing
|
||||
# TEST condition. Any test that appears with the message (change state)
|
||||
# TEST indicates that we've already run the particular test, but we are
|
||||
# TEST running it again so that we can change the state of the data base
|
||||
# TEST to prepare for the next test (this applies to all other recovery
|
||||
# TEST tests as well).
|
||||
# TEST
|
||||
# TEST These are the most basic recovery tests. We do individual recovery
|
||||
# TEST tests for each operation in the access method interface. First we
|
||||
# TEST create a file and capture the state of the database (i.e., we copy
|
||||
# TEST it. Then we run a transaction containing a single operation. In
|
||||
# TEST one test, we abort the transaction and compare the outcome to the
|
||||
# TEST original copy of the file. In the second test, we restore the
|
||||
# TEST original copy of the database and then run recovery and compare
|
||||
# TEST this against the actual database.
