Update:

1) I found the command:

 --stop-after-init

which seems to work but exists with code 1, meaning, it will be interpreted as an error. Any ideas about that?

Thx

I had this same problem. Additionally I wanted an interactive way of running my test quite continuously during development...

I created an open source script to solve both use-cases:

Feedback welcome :)

To run it inside of docker you'll need 'docker in docker', I believe.
