I am not sure if testcontainers suits our needs, inspite of having "clean" containers to work with for every/specific tests and executing tests without extra preperations like starting and stopping the containers manually for a single test:

• With a current build time of ~18min, starting and stopping individual containers (kafka, elasticsearch) for specific tests would increase the build time substantially.
• When containers for agent and frontier would be needed, we would have to construct custom images from our .deb's, which probably would also increase the build time.
