When doing tests while investigating WT-8025, I wanted to run many-collection-test on an existing database and I could not.
Reproducing the error:
Run the script with clean-and-populate task ... Run the script again without specifying the task
The script needs to be corrected to:
- Allow the task input argument to be undefined
- Not exit if a variable is undefined
Another issue I faced is when the replica set was being initialized by the test while it was already set up:
pymongo.errors.OperationFailure: already initialized, full error: {'ok': 0.0, 'errmsg': 'already initialized', 'code': 23, 'codeName': 'AlreadyInitialized', '$clusterTime': {'clusterTime': Timestamp(1630462114, 1), 'signature': {'hash': b'\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00', 'keyId': 0}}, 'operationTime': Timestamp(1630462114, 1)}
To correct this, we need to fix the condition when setup_mongodb() is called. We are calling it if oplog is set to True which seems wrong. It should be called when populate is set to True. This makes me think that the oplog variable can be fully removed as it is not used anywhere else.

Definition of done:
Make sure the test can run with and without specifying the task name.
