Monkey Patching Functions

monkey-patch.py

# So, a bit like mocking/patching, it depends on how the thing you're patching is imported *where it's used*.

# If the code that uses it is in a module called `client`, you'd want to do one of the following:

# If client.py looks like this:
from django.things import victim

def useful_function():
  victim(blah)

# ... then you'd monkey patch it like this in your own code:

import client # ensure that client is loaded into memory
client.victim = my_monkey   # Replace the top-level variable with your own value

# But if client.py looks like this:
import django.things

def useful_function():
    django.things.victim(blah)
    
# ... then you need to patch it in `things`, so you do this:
import django.things    # ensure django.things is loaded
django.things.victim = my_monkey    # Replace its top-level variable with your own value
