This code in wttest.py
. except wiredtiger.WiredTigerError as e: print("Failed wiredtiger_open: dir '%s', config '%s'" % \ (home, conn_param)) raise e
leads to this in test_txn19.py
if expect_fail: with self.expectedStdoutPattern('Failed wiredtiger_open'): errmsg = '/WT_TRY_SALVAGE: database corruption detected/'
We should report errors to stderr, not stdout.
