Hello, I'm really dumb and have never written tests before 🥲
I'm just really good at reading code and copy/pasting.

If you're willing to create tests, that'd be awesome.
Additionally, I'd be more than willing to hop on a zoom call to work together on this, so I can do it myself in the future. I love this repo, and would like to contribute more in the future as Docker continues to grow.

Apologies, i was quite busy those last few weeks, I skipped your message :(

No worries about it. While I won't really have the time to do a zoom call, I can write the test myself and you will be able to see what the test code should look like. Hopefully, that will help you understand a bit huw unit testing works.

I should have some time to make the unit tests Thursday :)
