Print reminder to update things when testing
Please give a one-sentence summary of the feature you would like to see.
When developers are testing the app, they should see a reminder when they start the app, on what to update.
Please give as many details as possible about the requirements for the feature.
Since most of us developers are using ngrok for tunneling and we are frugal, we are using the free version of ngrok, which means that the ngrok URL changes every single time we launch it. There are a couple of things that are tied to the URL. Remembering them all (and not forgetting any one of them) is a challenge, and it might be better if we use checklists.
Please list any additional context.
Less mental remembering things.
Since we are phasing out TESTING config, there is no longer a reliable way to check whether the app is testing (we know that apps with USE_AWS_LOCAL set must be testing, but not all of them use it). May be a good idea to print the message out every single time the server restarts at logging.info level.
