This is looking good @PeculiarE, good job 🎉 🎉 . Maybe you could do some refactoring on a follow up Pr for some of the things code climate is highlighting? These could also be good ftos am happy to help on those. Really love the tests! thanks

Thank you @cesswairimu! And yes, I do have 'code refactoring' noted down in my personal list of future project improvements 😅. I'd really appreciate it if you could help out. Thank you ❤️

This looks great, i just made one request on named attributes in a test method. Then we can merge this!

[jywarren]

Woohoo! Great work.
