Testing resources and workflow

Hello, Kind of new around here. Anyone wants to share with me their workflow? Which resources are your go to resources?

I am interested in your workflow for writing smart contracts tests. I see on Oppenzppelin's GitHub there are a lot of tests, any other resources or projects with great test code?

By the way does anyone wants to be friends? I Would love a short 'test writing' peer coding session to learn from coding, sharing and exchanging ideas. Please let me know if you are interested
