My guess is that is accidental - that the result of valid_session does not
get used.

The second user is generated with mock_model, which does not save anything
to the database, so I doubt that's the underlying issue.

If the idea here is that the session user is removing him/herself from the
system, then the example should set up _that_ user in the session e.g.
it "destroys the requested user" do
user = User.create! valid_attributes
expect {
delete :destroy, {:id => user.to_param}, {:user_id => user.id}
}.to change(User, :count).by(-1)
end
end
Since :user_id is the only key used in destroy, I _think_ this should work.
