Overview

Package nettest provides a set of network helpers for when unit testing networks

Uses a channel log the messages recieved by the server

Usage:

done := make(chan string)
addr, sock, srvWg := CreateServer(t, tc.net, tc.la, done)
defer srvWg.Wait()
defer os.Remove(addr.String())
defer sock.Close()

s, err := net.Dial(tc.net, addr.String())
defer s.Close()
fmt.Fprintf(s, "test message\n")
if "test message\n" != <-done {
    t.Error("message not recieved")
}

Functions

func CreateServer

func CreateServer(t *testing.T, n, la string, done chan<- string) (addr net.Addr, sock io.Closer, wg *sync.WaitGroup)

CreateServer creates a network server that will output all messages to the done channel for use with testing

It can create `udp`, `unixgram`, and `tcp` networks

Example:

done := make(chan string)
addr, sock, srvWg := CreateServer(t, tc.net, tc.la, done)
defer srvWg.Wait()
defer os.Remove(addr.String())
defer sock.Close()

s, err := net.Dial(tc.net, addr.String())
defer s.Close()
fmt.Fprintf(s, "test message\n")
if "test message\n" != <-done {
    t.Error("message not recieved")
}
