@henrykironde what was the secret here, before I merge.

@bw4sz @ethanwhite, while this solution works, it's not ideal. The script relies on keeping the console output clean to force the test to pass, which feels like a workaround. It's challenging to make verbose=False tests pass reliably since other output (beyond the expected print statements) might be present.

        if mosaic:
             # Suppress output if not verbose
             if not verbose:
                 f = io.StringIO()
                 with contextlib.redirect_stdout(f):
