(* delegate registration *)
(**************************************************************************)
(* A delegate is a pkh. Delegates must be registered. Registration is
done via the self-delegation of the implicit contract corresponding
to the pkh. The implicit contract must be credited when the
self-delegation is done. Furthermore, trying to register an already
registered key raises an error.
In this series of tests, we verify that
1- unregistered delegate keys cannot be delegated to,
2- registered keys can be delegated to,
3- registering an already registered key raises an error.
We consider three scenarios for setting a delegate:
- through origination,
- through delegation when the implicit contract has no delegate yet,
- through delegation when the implicit contract already has a delegate.
We also test that emptying the implicit contract linked to a
registered delegate key does not unregister the delegate key.
*)
(*
Valid registration
Unregistered key:
- contract not credited and no self-delegation
- contract credited but no self-delegation
- contract not credited and self-delegation
Not credited:
- no credit operation
- credit operation of 1μꜩ and then debit operation of 1μꜩ
*)
(** A- unregistered delegate keys cannot be used for delegation *)
(* Two main series of tests: without self-delegation, and with a failed attempt at self-delegation
1- no self-delegation
a- no credit
- no token transfer
- credit of 1μꜩ and then debit of 1μꜩ
b- with credit of 1μꜩ.
For every scenario, we try three different ways of delegating:
- through origination (init origination)
- through delegation when no delegate was assigned (init delegation)
- through delegation when a delegate was assigned (switch delegation).
2- Self-delegation fails if the contract has no credit. We try the
two possibilities of 1a for non-credited contracts.
