How would I go about testing things through GMod 13?

[NnyAskC]

I've heard it has (or plans to have) better reporting and would like to test things through it, but the file structure is a lot different.

Where would I put random scripts and addons for testing?

Well, considering the vanilla addon system doesn't work for Garry's Mod 13, it'd be kinda difficult.

Leave it to the developers to test their own scripts.

I've been developing in gamemodes rather than having addons :(

Haha, Myself and Deadman123's Hacker Gamemode is going to be tested on GMod, might release it when it's done for you.

The legacy system for addons was readded in beta 15.

Furthermore, you can and always have been able to put lua scripts into the lua folder and call them in the console. How have you normally been doing it?

Game modes function the same, and info.txt was removed and replaced with something similar in function.
