How to test telegram chat bots that work on prod?

Question

Bots

If there is a chat bot that works and people use it (constantly), and I want to make edits / add a feature to it, how can I make sure that the bot does not crash due to incorrect editing? because I want to test the whole thing
, in my head there is an option to create another chat bot for testing, which will have the same code as on the prod, but only I can make changes to it. And when I test and see that everything works correctly, then I can upload the changes to the prod.
Then the question arises, how to make it work correctly?
1. Make two windows in the IDE, where one project is a dev code, and the second is a pro code
2. Build a CI / CD in which there will be two development / production branches?

Answer 1

The second option, of course. The first is savagery. Good idea about two bots
