In Book 14 of The Odyssey, why does Odysseus test Eumaeus' loyalty?

I think the biggest reason for Odysseus wanting to test
the loyalty of Eumaeus is that he has been away from Ithaca for so long, and he knows
that there is a hostile force of the suitors in his palace trying to woo Penelope and
take his wife and kingdom away from him. This must have made him incredibly unsure about
his position. Although Athena has told him to go to Eumaeus, the wily Odysseus is never
going to trust somebody straight off without testing their loyalty and checking that
their character has not changed and they are still completely devoted to him. This is
what we see in Book 14: Odysseus devises a number of tests to prove beyond a shadow of a
doubt that Eumaeus, the faithful swinherd, is still loyal to his
master.
