Noremac Asks: Should I avoid testing on live data for acceptance testing?
My team is transitioning into using BDD and cucumber. We are creating acceptance tests and from what I understand we want to be high level, happy path type tests that are hitting our features end to end as a user would.

How do we:

1. Ensure the changing data on a live environment won't cause tests to have false failures?
2. Protect changes deployed to an environment from impacting all customers if things go wrong?

Alternatively we've considered having a sterile, repeatable database that we could use for the app to run against. However, then how would we:

1. Ensure that we don't miss features failing because the data isn't representative of live data.
2. Avoid testing too closely to implementation rather than behavior

I would love to get some pointers on best practices here.

costa rica Asks: Gunicorn error: unrecognized arguments: run:app (using waitress and nginx)
I am using an AWS ubuntu machine to run a Flask Blueprints application. I have been able to run in development mode where my service file has an ExecStart like this: ExecStart=/home/ubuntu/environments/venv_wsh06api/bin/gunicorn -w 3 -b 0.0.0.0:8001 run:app

But now I want to run using waitress. I have tried every iteration I can think of: gunicorn waitress -w 3 -b 0.0.0.0:8080 run:app

and each is giving some version of “gunicorn: error: unrecognized arguments: run:app”. It’s always last argument where I am telling what app to run that is being called out as the error.

I have seen some very elaborate run.py files but none seem to apply to me. I know there are a few other posts and even a Medium article that closely address my needs. I’ve parsed through them in detail alternating things and still not getting anywhere.

Any advice greatly appreciated. Even a suggestion where to look would be wonderful. Thanks.

jack parsons Asks: I am starting a new rails app(Rails 7.0.4) with the option --webpack=react and I have no /app/javascript/packs folder
I have installed node and npm I tried brew install yarn but that may have failed.... I am copying a tutorial by Zayne on how to get ruby on rails running with react and he used the command rails new react-app --webpack=react and he got a folder called /app/javascript/packs with a file called hello_react.jsx, maybe this is because he is on RoR 6 and I am using version Rails 7.0.4.
