While RSpec may also be used for unit or integration tests, its download count is quite impressive. As a comparison, the most-downloaded Cucumber v3.1.2 is merely 8.8 million.

Need help regarding ruby install on Mac
pry and rspec are gems. You had at least 3 rubies (system, rbenv, rvm), and each ruby puts its gems in a different folder. Your rspec might be in a folder for rbenv's ruby. If you switched to rvm's ruby, then bundle exec rspec would fail because rvm's ruby can't find rbenv's gems.

Inherited rails app - what the hell are all these rack timeout lines in the log?
Without seeing more of the app, it's tough to say for certain, but one gem you might find helpful is the [bullet](https://github.com/flyerhzm/bullet) gem -- set this up in the app then start browsing around the app in development. If you have any N+1 queries or other minor optimizations that could be done it will inform you about them.

Understanding N and 1 queries problem
There's a Ruby gem called Bullet that identifies and warns developers about N+1 problems. You can also have it fail tests if detected.
I don't know if the approach is possible with every ORM or if it's just leveraging some Ruby perks, but I can't think of a good reason why you wouldn't use the equivalent everywhere.

Understanding and Fixing N+1 Query
As a Rails developer, recently I found Bullet [0] which helps massively in dealing with eager loading. For some reason I expected the framework to manage this sort of thing for me, even when Rails actually does a ton out of the box already. Only while refactoring I picked up on queries dragging performance. Oh well...

How do you find the cause of slowness in your app?
This is good advice, it'll likely pick out some glaring issues right away. I would generally recommend looking at DB queries here too and recommend Bullet, but most software like DataDog, AppSignal etc will often also point N+1 and issues like it out.
