Overview

When reviewing the PR that added these pages, I thought the + icons were from the diff tool, not present in the actual file! CC @TG199 as previous PR author to double-check changes like that :) nbd, my fault for being too lazy to build and preview the changes this time. I'll be more careful in the future

Thanks for catching that @mark-wiemer! You're absolutely right - those + symbols shouldn't be in the actual content. I must have accidentally included them when working with the diff view.
Appreciate you cleaning this up, and I'll be more careful to preview the built docs locally before submitting future PRs. Good lesson learned! 🙂
Question about completing #5248: Now that we have the related tools documentation migrated, should I also tackle moving the appropriate code examples to mocha-examples repo I'm thinking things like:

The EventEmitter spy examples from the original Spies wiki page
Test coverage integration examples mentioned on the wiki homepage
Framework integration examples (Express/Connect, etc.)

Would that be the next logical step, or do you prefer to handle the examples migration separately?
