How, exactly, does one "test" kamikazes?

I was doing some research on Japanese aircraft carriers (don't ask why), and came upon a site with brief descriptions on all the various assorted classes. (There were more than I thought.) Anyway, I was given pause over this passage and photo (never mind the Akagi label, it should be Aso):

The design of this class closely followed that of the Hiryu class, but with the bridge on the starboard side. The keels were laid down for this class of ships in 1942-43, but only three of them ever reached completion. Work stopped on the Kasagi in April, 1945 when she was 84% complete, no armament having been fitted. Work also stopped on the Iso and the Ikoma in January, 1945 due to lack of building materials. They only had been completed to hanger deck level (60% complete with no hanger or armament fitted). All ships had been launched and left in their incomplete state until August, 1945 when they were surrendered and then later scrapped. The hull of the Aso had been used as a Kamikaze test-bed and she was in a poor state of repair, half sunk in shallow water when surrendered. The Unyru was sunk by the USS Redfish in the East China Sea in December, 1944.

Am I reading "test-bed" wrong? Did they test their kamikazes? Um, how did that work out?
