Answer 1

From your error messages, you are using Python3.7.

It is possible that you are using the deprecated getfuncargvalue instead of getfixturevalue as described here .

Answer 2

Try to update the dependencies of the project, the default dependencies of Pytest, pymongo and Flask are quite old. I managed to get the tests passing after updating them.

Answer 3

Same happened to me. I added attrs==19.1.0 to requirements.txt and it worked!
