I'm looking at the SIKE known answer tests and am realizing that I'm confused on all the different terms in a Diffie-Hellman key exchange.

From the Wikipedia page, I would think there would be a public key and 2 secret keys, then a shared secret. However, the KAT provides a public key, a secret key, a shared secret, and a ciphertext. What exactly is the ciphertext, and where is the secret key?

This Wiki page describes SIDH, a key exchange protocol.

SIKE is a key encapsulation mechanism, like all entries in the NIST PQ competition, it has a different API.
