Are you sure the tests for Robot Simulator work?

Yes:

What exactly is failing for you?

Though indeed I really need to update the erlang used by the actions

Having done some further checks, I think I found what you are talking about, you probably receive a relatively generic error message when trying to run the tests.

Saldy this is a problem for robot-simulator as well as some further exercises, and I have not yet been able to look into this.

For some reasons the tests are failing in the test runners docker environment, but not in/on real systems.

Back when I discovered it first, I didn't have the time to debug it and forgot about it later on.

Thanks, I understood it now after Brujo Benavides explained this to me.

This problem expects that you send and receive messages.
