Unit Tests don't clean up docker containers

[slominskir]

Description

If you run a unit test over and over the number of stopped containers in Docker just piles up.

How to reproduce

Run the unit tests for this project, or even target a specific one and run it multiple times. It uses trivup to launch, but doesn't seem to cleanup after itself. I'm manually deleting the containers from Docker Desktop after a round of testing.
