AWS Lambda function is not updating in basic test environment

I'm trying to set up a very basic AWS Lambda script, but I struggle to get the AWS Lambda Test functionality to recognize the changes I make.

To setup the simplest possible test, I created a new AWS Lambda function for Python 3.7. I then make a simple change in the code as below, add a test output and run Test:

import json

def lambda_handler(event, context):
    # TODO implement
    return {
        'statusCode': 200,
        'body': json.dumps('I changed this text')
    }

I've verified that Version: is set to $LATEST - yet when I run the test, there is no change in my output - it keeps returning the original code output. Further, if I try to export the function, I get the original code - not my updated code above (despite having saved it).

I realize this seems very basic, but I wanted to check if others have experienced this as well.

Based on feedback, it seems hitting Deploy is required in order to be able to test the updated function

Even with hitting deploy, there's a definite delay. Try adding a print statement and hitting deploy and then testing. This will show that it often doesn't accept the new code right away. EXTREMELY frustrating for debugging. I have to literally refresh my lambda console page to get the changes to take.
