Passing mock boto3 client in init.py

Question

I am trying to figure out how to pass a mock boto3 client to init.py with pytest, but am having some trouble. When I pass my fixture into the function I'm trying to test, the function called in init.py still tries to use a real instance of the boto client when get_secret is called instead of the one I'm mocking. Wondering what I am doing wrong here?

As an example:

init.py

from helpers.token_helper import get_token
from my_jobs.jobs import job_1, job_2

params = {'token': get_token()}
job_1()
job_2(params)

token_helper.py

import os
from aws_helper import get_secret

def get_token():
    token = os.getenv("MY_TOKEN")
    if not token:
        try:
            token = get_secret("my-secret/my-token")
        except Exception as e:
            raise Exception(f"could not get token")
    return token

aws_helper.py

import boto3

def get_secret(secret_name):
    client = boto3.client("secretsmanager", region_name="us-east-1")
    try:
        response = client.get_secret_value(SecretId=secret_name)
        return response["SecretString"]
    except Exception as e:
        print(e)
        raise e

jobs.py

def job_1():
    return 'yay'

def job_2(params):
    print(params)
    return 'boo'

test_jobs.py

import pytest
import boto3
import moto
from my_jobs.jobs import job_1

@pytest.fixture(scope="session")
def mock_boto3_client():
    with moto.mock_secretsmanager():
        client = boto3.client("secretsmanager", region_name="us-east-1")
        secret_name = "my-test-secret"
        secret_value = "my-test-secret-value"
        client.create_secret(Name=secret_name, SecretString=secret_value)
        yield client

def test_job_1(mock_boto3_client):
    response = job_1()
    assert response == 'yay'
