10 //! Functional tests for the BOLT 12 Offers payment flow.
12 //! [`ChannelManager`] provides utilities to create [`Offer`]s and [`Refund`]s along with utilities
13 //! to initiate and request payment for them, respectively. It also manages the payment flow via
14 //! implementing [`OffersMessageHandler`]. This module tests that functionality, including the
15 //! resulting [`Event`] generation.
17 //! Two-node success tests use an announced channel:
21 //! While two-node failure tests use an unannounced channel:
25 //! Six-node tests use unannounced channels for the sender and recipient and announced channels for
26 //! the rest of the network.
32 //! Alice ... Bob -------- Charlie ... David
38 //! Unnamed nodes are needed to ensure unannounced nodes can create two-hop blinded paths.
40 //! Nodes without channels are disconnected and connected as needed to ensure that deterministic
41 //! blinded paths are used.
