What type of ki tests? Do you mean things like unbendable arm, fudotai sieza and tachi, unliftable and/or unbendable body? Those are all included in our normal testing (except unbendable body...we just do that for fun
Oh BTW, I practice seidokan which was founded by the late Rod Kobayashi, yet another student of Tohei Sensei
And yes, ki is mentioned all the time.
