Types

type Request

type Request struct {
	Req proto.Message
	Err error
}

Request wraps the request protobuf (xds/LRS) and error received by the Server in a call to stream.Recv().

type Response

type Response struct {
	Resp proto.Message
	Err  error
}

Response wraps the response protobuf (xds/LRS) and error that the Server should send out to the client through a call to stream.Send()

type Server

type Server struct {
	// XDSRequestChan is a channel on which received xDS requests are made
	// available to the users of this Server.
	XDSRequestChan *testutils.Channel
	// XDSResponseChan is a channel on which the Server accepts xDS responses
	// to be sent to the client.
	XDSResponseChan chan *Response
	// LRSRequestChan is a channel on which received LRS requests are made
	// available to the users of this Server.
	LRSRequestChan *testutils.Channel
	// LRSResponseChan is a channel on which the Server accepts the LRS
	// response to be sent to the client.
	LRSResponseChan chan *Response
	// NewConnChan is a channel on which the fake server notifies receipt of new
	// connection attempts. Tests can gate on this event before proceeding to
	// other actions which depend on a connection to the fake server being up.
	NewConnChan *testutils.Channel
	// Address is the host:port on which the Server is listening for requests.
	Address string
	// contains filtered or unexported fields
}

Server is a fake implementation of xDS and LRS protocols. It listens on the same port for both services and exposes a bunch of channels to send/receive messages.

func StartServer

func StartServer() (*Server, func(), error)

StartServer makes a new Server and gets it to start listening on a local port for gRPC requests. The returned cancel function should be invoked by the caller upon completion of the test.

func (*Server) XDSClientConn

func (xdsS *Server) XDSClientConn() (*grpc.ClientConn, func(), error)

XDSClientConn returns a grpc.ClientConn connected to the fakeServer.
