Yes, currently the test works like:

do_test_setup();
read_from_debugfs_file();
check_results();

and the middle step stays the same. But of course in general case there
could be argument passing etc, even though the test for this issue
doesn't need them.

Myself I don't see the problem with just adding a file under debugfs and
bind to its read.
