"""
Automated test for https://github.com/taurus-org/taurus/issues/1118

It requires docker-compose to be installed.

- If the bug is not present, it finishes in after counting to 30 and 
printing "SUCCESS!"
- If the bug is present, crashes (non-zero exit value) at some point of the 
count (~15)

Note: reproducibility is not 100%, but in my case it is at least 9/10
