Hi @<1535069219354316800:profile|PerplexedRaccoon19>
What do you mean by simulate?
You can manually setup and run a Task if you need,
'clearml-agent execute --id task_id' add --docker for docker mode.
This will setup the env and run the task

I need to mock it - because I'm writing some unittests

Ohh if this is the case, you might also consider using offline mode, so there is no need for backend
