At this point, most software engineers see the value of testing their software regularly. But are you testing your data engineering as well?

@L3n Where do you create your A and B dependencies? Where do you create your factory? Where do you bootstrap your entire application?
@L3n As a complicated example, you can check how I initialize dependencies here: github.com/Zomis/Games/blob/main/games-server/src/main/kotlin/… . Everything that is needed is somehow passed into other classes. Passing both the A and B dependencies to the factory would make sense if that's all that's needed to create the other commands.
However, I would also like to ask how/when/where these commands are used? Are they created and used at the same time, or are they created much much earlier than being used? Or what happens? My impression is that it's some kind of console commands, i.e. write something in stdin and it gets interpreted as a command which is then executed?

I just saw a link at the end of this answer to a list of words, which I hadn't seen before. I wasn't familiar with the domain so I checked out the main page - it has some great animated gifs
I noticed this humorous list of quotes from children (perhaps from exams?) and used my in-browser Google Translate plugin - it did fairly well
