Getting NameError: name 'bot_token' is not defined py.test

I am getting hit with a NameError: name 'bot_token' is not defined when I try to run pytest, even though I am importing the all the necessary files (or clearly maybe not).

Directory structure:

bot/
-src/
--__init__.py
--my_bot.py
--bot_token.py
-tests/
--test-sample.py

test-sample.py

import src.my_bot
import src.bot_token

def test
...

my_bot.py

import src.bot_token

client.run(bot_token.bot_token)

...

bot_token.py

bot_token = 'blahblahblah'

When I try to run python3 -m pytest, I get hit with the following error:

_________________________________________________ ERROR collecting tests/test_sample.py _________________________________________________
tests/test_sample.py:2: in <module>
    import src.my_bot

E   NameError: name 'bot_token' is not defined
======================================================== short test summary info ========================================================
ERROR tests/test_sample.py - NameError: name 'bot_token' is not defined

How do I manage this?
