	channel *p2p.Channel,
	peerID types.NodeID,
	send proto.Message,
	receive proto.Message,
)

RequireSendReceive requires that a given Protobuf message is sent to the given peer, and then that the given response is received back.

Types

type Message

type Message = gogotypes.StringValue

Message is a simple message containing a string-typed Value field.

type Network

type Network struct {
	Nodes map[types.NodeID]*Node
	// contains filtered or unexported fields
}

Network sets up an in-memory network that can be used for high-level P2P testing. It creates an arbitrary number of nodes that are connected to each other, and can open channels across all nodes with custom reactors.

func MakeNetwork

func MakeNetwork(ctx context.Context, t *testing.T, opts NetworkOptions) *Network

MakeNetwork creates a test network with the given number of nodes and connects them to each other.

func (*Network) MakeChannels

func (n *Network) MakeChannels(
	ctx context.Context,
	t *testing.T,
	chDesc *p2p.ChannelDescriptor,
) map[types.NodeID]*p2p.Channel

MakeChannels makes a channel on all nodes and returns them, automatically doing error checks and cleanups.

func (*Network) MakeChannelsNoCleanup

func (n *Network) MakeChannelsNoCleanup(
	ctx context.Context,
	t *testing.T,
	chDesc *p2p.ChannelDescriptor,
) map[types.NodeID]*p2p.Channel

MakeChannelsNoCleanup makes a channel on all nodes and returns them, automatically doing error checks. The caller must ensure proper cleanup of all the channels.

func (*Network) MakeNode

func (n *Network) MakeNode(ctx context.Context, t *testing.T, opts NodeOptions) *Node

MakeNode creates a new Node configured for the network with a running peer manager, but does not add it to the existing network. Callers are responsible for updating peering relationships.

func (*Network) NodeIDs

func (n *Network) NodeIDs() []types.NodeID

NodeIDs returns the network's node IDs.

func (*Network) Peers

func (n *Network) Peers(id types.NodeID) []*Node

Peers returns a node's peers (i.e. everyone except itself).

func (*Network) RandomNode

func (n *Network) RandomNode() *Node

RandomNode returns a random node.

func (*Network) Remove

func (n *Network) Remove(ctx context.Context, t *testing.T, id types.NodeID)

Remove removes a node from the network, stopping it and waiting for all other nodes to pick up the disconnection.

func (*Network) Start

func (n *Network) Start(ctx context.Context, t *testing.T)

Start starts the network by setting up a list of node addresses to dial in addition to creating a peer update subscription for each node. Finally, all nodes are connected to each other.

type NetworkOptions

type NetworkOptions struct {
	NumNodes   int
	BufferSize int
	NodeOpts   NodeOptions
}

NetworkOptions is an argument structure to parameterize the MakeNetwork function.

type Node

type Node struct {
	NodeID      types.NodeID
	NodeInfo    types.NodeInfo
	NodeAddress p2p.NodeAddress
	PrivKey     crypto.PrivKey
	Router      *p2p.Router
	PeerManager *p2p.PeerManager
	Transport   *p2p.MemoryTransport
	// contains filtered or unexported fields
}

Node is a node in a Network, with a Router and a PeerManager.

func (*Node) MakeChannel

func (n *Node) MakeChannel(
	ctx context.Context,
	t *testing.T,
	chDesc *p2p.ChannelDescriptor,
) *p2p.Channel

MakeChannel opens a channel, with automatic error handling and cleanup. On test cleanup, it also checks that the channel is empty, to make sure all expected messages have been asserted.

func (*Node) MakeChannelNoCleanup

func (n *Node) MakeChannelNoCleanup(
	ctx context.Context,
	t *testing.T,
	chDesc *p2p.ChannelDescriptor,
) *p2p.Channel

MakeChannelNoCleanup opens a channel, with automatic error handling. The caller must ensure proper cleanup of the channel.

func (*Node) MakePeerUpdates

func (n *Node) MakePeerUpdates(ctx context.Context, t *testing.T) *p2p.PeerUpdates

MakePeerUpdates opens a peer update subscription, with automatic cleanup. It checks that all updates have been consumed during cleanup.

func (*Node) MakePeerUpdatesNoRequireEmpty

func (n *Node) MakePeerUpdatesNoRequireEmpty(ctx context.Context, t *testing.T) *p2p.PeerUpdates

MakePeerUpdatesNoRequireEmpty opens a peer update subscription, with automatic cleanup. It does *not* check that all updates have been consumed, but will close the update channel.

type NodeOptions

type NodeOptions struct {
	MaxPeers     uint16
	MaxConnected uint16
	MaxRetryTime time.Duration
}
