模拟/补丁 function 在视图中

Question

from flask import request
from flask.views import MethodView
from unittest.mock import patch
from router.views.time_view import (
    _utcnow
)

class StateSetupView(MethodView):
    @app.route("/state-setup", methods=['POST'])
    def post():
        print(f"Non-mocked version: {_utcnow()}")
        with patch('router.views.time_view._utcnow', return_value = "LOL"):
            print(f"Mocked version: {_utcnow()}")

I can't seem to mock the function return value in runtime. The code above returns the same value in both instances. I do not want to wrap this in a pytest, this needs to work in a view.

Answer 1

Just simple replacing the function straight up worked.

router.views.time_view._utcnow = lambda: 12346789
