The test depends on registration of DAMON_OPS_PADDR. It would be registered only when CONFIG_DAMON_PADDR is set. DAMON core kunit tests do fake ops registration for such case. However, the functions for such fake ops registration is not available to DAMON debugfs interface. Just skip the test in the case.
