You can give the test the parameter 'w' for writing files or 'h' for
help (it's calling getopt so I think this is `-w` and `-h`).

I think the test itself by default just doing memory I/O and
calculating the md5 is not a bad idea. Just means you have to re-run
it manually to get actual output files. Also it is one of the few
API-based tests that we have around.

For output files, you can check the diff with something like L-SMASH's
boxdumper with the `--box` parameter, which dumps the box structure of
the file. Then you can diff those two outputs from before/after.

Best regards,
