Getting started

This is a list of tests that will be pretty easy to get started with, even if you're new to GLuaTest _(or even unit testing as a whole!)_

If you are still new to testing, please consider reading through GLuaTest's [Guided Testing Walkthrough]()

And if you decide to tackle one of these, please keep two things in mind:
1. Feel free to reach out! Message me directly on Discord, or join our [Dev Support](https://discord.gg/5JUqZjzmYJ) Discord Server
2. GLuaTest has a [rigorous set of documentation](https://github.com/CFC-Servers/GLuaTest?tab=readme-ov-file#writing-tests-%EF%B8%8F) - be sure to give it a skim!

Additionally, please be sure to read through the [Contributing](https://github.com/CFC-Servers/gmod_tests?tab=readme-ov-file#contributing) instructions in the README
