Get a free server port for testing with
use Test::Util::ServerPort; my $port = get-unused-port(); # .. start some server with the port
This is a utility to help with the testing of TCP server software.
It exports a single subroutine
get-unused-port that will return
a port number in the range 1025 - 65535 (or a specified range
as an argument,) that is free to be used by a listening socket. It
checks by attempting to
listen on a random port on the range
until it finds one that is not already bound.
Assuming you have a working Rakudo Perl 6 installation you should be able to install this with zef :
# From the source directory zef install . # Remote installation zef install Test::Util::ServerPort
Suggestions and patches that may make it more useful in your software are welcomed via github at:
This is free software.
