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.
