   1 //! Test that no series of bytes received over the wire/connections created/payments sent can
   2 //! result in a crash. We do this by standing up a node and then reading bytes from input to denote
   3 //! actions such as creating new inbound/outbound connections, bytes to be read from a connection,
   4 //! or payments to send/ways to handle events generated.
   5 //! This test has been very useful, though due to its complexity good starting inputs are critical.
