Docs Request: Unit Testing Module

[Valcoholics]

What is the issue you are encountering with the docs?

We need a module just for understanding the testing suite, code formatting/following a style guide for writing functions. I've got a good handle on many concepts, but the way tests are expecting exact lettering for functions is holding me back from getting those NFT stickers.

Information that's missing:

• How to find the Unit Tests
• FAQ answer to common error "Something is wrong with the contract at the address you are trying to submit"
  "It is likely that your function signatures do not match what is expected." which has been asked over 10 times in the Base Discord

Describe the solution you'd like to see.
