phpunit finishes successfully, but when coverage is disabled, it does fail

Current behavior

Generating code coverage report in PHP format ... done [00:00.033]
Class "Behat\MinkExtension\Context\RawMinkContext" not found
Error: Process completed with exit code 2.

How to reproduce

see https://github.com/atk4/ui/pull/1628/checks?check_run_id=2476898808#step:9:45

Expected behavior

When class is not loaded in any phpunit tests, zero coverage must be generated even if parent class is not loadable and no error must be generated.
