QUESTION
I'd like to write some unit tests of our mongo code using mongomock as the backend. However, Flask-PyMongo adds a convenience class (find_one_or_404
) on top of the Collection class that means that I can't do a straight-up MongoMock substitution. Any attempts at monkeypatching this function onto the Collection class don't seem to be working (I assume it has something to do with the overridden __getattr__
- every time I try I get TypeError: 'Collection' object is not callable
on db.collection_name.find_one_or_404({})
). What are my options here, besides just not using this function?

Say I have the following MongoDB collection (am using mongomock
for this example so it's easy to reproduce):

, because it requires a single filter which in your use case would not work as each filter is different.
A simpler construct uses upsert=True
to avoid the insert/update logic, and also sets all the fields specified in the record which is less coding :

No vulnerabilities reported
Install mongomock
You can use mongomock like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
