Tests total: 7, failed: 1, passed: 6
Error: 1 test(s) failed
Usage:
  crd-to-sample test [flags]

Flags:
  -h, --help     help for test
  -u, --update   Update any existing snapshots.

2024/08/19 08:23:42 failed to run command: 1 test(s) failed

Arguably the output could be nicer and the failure including the HELP of the command is ugly.
