(You may already know these two but I figured I’d share just in case.)
As far as coding goes, I’d highly suggest utilizing CSIDE which was developed by a moderator from here (It’s CJW but I don’t want to summon them, lol) in order to help writers programming choicescript games succeed. It’s intuitive, even for first time coders in my experience, and has about a million tools and shortcuts on there. I’m pretty sure you can run some amount of tests on it too.
Furthermore, you can peek into other authors’ code and review how they accomplished their games’ creation as a great learning tool. You can find how to do that here. Don’t be intimidated though, it’s quite simple once you plug everything in.
