AttributeError: module 'uwsgi' has no attribute 'masterpid'

Question

I'm trying to run some unit tests on a Flask api built in python, but when importing the app in the setUp of the class, I'm getting this:

def setUp(self):

  from app import OPERATIONS_CATALOG_SVC

test/common/operations/test_common_services.py:10:

There may be name conflict somewhere. Make sure you do not name your file/folder with python package name.

Start from scratch and it should be fine.

masterpid() is available in uwsgi package.

Link to the document : https://uwsgi-docs.readthedocs.io/en/latest/API.html#uwsgi-masterpid

uwsgi.masterpid()

return the current pid of the master process
