• Applying SNOW-1825473 adding pat authentication integration #2122 was additionally tested with the following script:

from snowflake.connector import connect
from snowflake.connector.aio import connect as aconnect

import asyncio

PAT_params = {...}
PAT_params["authenticator"] = "PROGRAMMATIC_ACCESS_TOKEN"
PAT_params["token"] = ...

async def test_pat():
   with connect(**PAT_params) as conn:
       with conn.cursor() as cur:
           cur.execute("SELECT 1")
           print(cur.fetchone())
           print("SYNC - OK")

   connection = await aconnect(**PAT_params)
   cur = connection.cursor()
   await cur.execute("SELECT 1")
   print(await cur.fetchone())
   print("ASYNC - OK")
   await connection.close()

asyncio.run(test_pat())
