1 //! Test that monitor update failures don't get our channel state out of sync.
2 //! One of the biggest concern with the monitor update failure handling code is that messages
3 //! resent after monitor updating is restored are delivered out-of-order, resulting in
4 //! commitment_signed messages having "invalid signatures".
5 //! To test this we stand up a network of three nodes and read bytes from the fuzz input to denote
6 //! actions such as sending payments, handling events, or changing monitor update return values on
7 //! a per-node basis. This should allow it to find any cases where the ordering of actions results
8 //! in us getting out of sync with ourselves, and, assuming at least one of our recieve- or
9 //! send-side handling is correct, other peers. We consider it a failure if any action results in a
10 //! channel being force-closed.
