Test code is total: we require it to always terminate or it's a failure! It also typically has 100% line and branch coverage. I feel way less nervous about refactoring tests, you can always just run them.

Terminad is a really interesting approach to rendering markdown in the CLI. It deliberately doesn't render links, so you can always see both the link text and the URL. In a browser you have hover to see URLs, but not necessarily in a terminal.

It's really satisfying to use a profiler for the first time on a project. I always find a big performance win with only a small code change. It's never the code that I expected to be slow, however!
