CheckSocket

A very simple Raku function to test if a TCP socket is listening on a given address or a UNIX domain socket on the specified path

Description

This module provides a very simple mechanism to determine whether something is listening on a TCP socket at the given port and address, or UNIX domain socket at a specified path. This is primarly for the convenience of testing where there may be a dependency on an external network service. For example:

 use Test;
 use CheckSocket;

 if not check-socket(80, "localhost") {
      skip-all "no web server";
     exit;
 }

# or

use Test;
use CheckSocket;

# Start some socket server concurrently
if wait-socket(80, "localhost") {
	# do some tests
}
else {
	skip-all "server didn't start in time";
}

Installation

You can install directly with zef:

# From the source directory
