NAME

Test::Alien::Synthetic - A mock alien object for testing

VERSION

version 1.67

SYNOPSIS

 use Test2::V0;
 use Test::Alien;
 
 my $alien = synthetic {
   cflags => '-I/foo/bar/include',
   libs   => '-L/foo/bar/lib -lbaz',
 };
 
 alien_ok $alien;

 done_testing;

DESCRIPTION

This class is used to model a synthetic Alien class that implements the minimum Alien::Base interface needed by Test::Alien.

It can be useful if you have a non-Alien::Base based Alien distribution that you need to test.

NOTE: The name of this class may move in the future, so do not refer to this class name directly. Instead create instances of this class using the Test::Alien#synthetic function.

ATTRIBUTES

cflags

String containing the compiler flags

cflags_static

String containing the static compiler flags

libs

String containing the linker and library flags

libs_static

String containing the static linker and library flags

dynamic_libs

List reference containing the dynamic libraries.

bin_dir

Tool binary directory.

runtime_prop

Runtime properties.

EXAMPLE

Here is a complete example using Alien::Libarchive which is a non-Alien::Base based Alien distribution.

 use strict;
 use warnings;
 use Test2::V0;
 use Test::Alien;
 use Alien::Libarchive;
 
 my $real = Alien::Libarchive->new;
 my $alien = synthetic {
   cflags       => scalar $real->cflags,
   libs         => scalar $real->libs,
   dynamic_libs => [$real->dlls],
 };
 
 alien_ok $alien;
 
 xs_ok do { local $/; <DATA> }, with_subtest {
   my($module) = @_;
   my $ptr = $module->archive_read_new;
   like $ptr, qr{^[0-9]+$};
   $module->archive_read_free($ptr);
 };
 
 ffi_ok { symbols => [qw( archive_read_new )] }, with_subtest {
   my($ffi) = @_;
   my $new  = $ffi->function(archive_read_new => [] => 'opaque');
   my $free = $ffi->function(archive_read_close => ['opaque'] => 'void');
   my $ptr = $new->();
   like $ptr, qr{^[0-9]+$};
   $free->($ptr);
 };

 done_testing;
 
 __DATA__
 
 #include "EXTERN.h"
 #include "perl.h"
 #include "XSUB.h"
 #include <archive.h>
 
 MODULE = TA_MODULE PACKAGE = TA_MODULE
 
 void *archive_read_new(class);
     const char *class;
   CODE:
     RETVAL = (void*) archive_read_new();
   OUTPUT:
     RETVAL
 
 void archive_read_free(class, ptr);
     const char *class;
     void *ptr;
   CODE:
     archive_read_free(ptr);
