How do I use logger in lambda?

On lambda, we have prepared the following scripts to verify logger operation:

import logging

deflambda_handler(event, context):
    # print("Received event:" + json.dumps(event,indent=2))"

    logging.basicConfig (level=logging.DEBUG)
    logger = logging.getLogger()
    logger.debug('test')

if__name__=='__main__':
    lambda_handler (None, None)

If you do this from the command line, the log will output correctly as follows:

$python lambda_function.py
DEBUG:root:test

However, if you do this on lambda, the logger does not appear.

Question:

How do I debug/info output the logger on lambda?

Is it not recorded in CloudWatch Logs?
