 In both cases, the test terminates as successful when the conductor receives the incremented state from all other nodes. Then, the conductor sends a special "kill" message to all known nodes and waits for them to disconnect.
 
 Metadata about the toplogy is currently read from an `identity_mapping.json` file that manually labels the type of node (bootstrap, regular, conductor). The conductor uses this to figure out information about all nodes in the network. The regular nodes use this to learn about their ip address and the addresses necessary to bootstrap onto the network. The boostrap nodes only use this to learn about their ip addresses.
