NAME

Test::Alien::Build - Tools for testing Alien::Build + alienfile

VERSION

version 2.83

SYNOPSIS

use Test2::V0;
use Test::Alien::Build;

# returns an instance of Alien::Build.
my $build = alienfile_ok q{
  use alienfile;

  plugin 'My::Plugin' => (
    foo => 1,
    bar => 'string',
    ...
  );
};

alien_build_ok 'builds okay.';

done_testing;

DESCRIPTION

This module provides some tools for testing Alien::Build and alienfile. Outside of Alien::Build core development, It is probably most useful for Alien::Build::Plugin developers.

This module also unsets a number of Alien::Build specific environment variables, in order to make tests reproducible even when overrides are set in different environments. So if you want to test those variables in various states you should explicitly set them in your test script. These variables are unset if they defined: ALIEN_BUILD_PRELOAD ALIEN_BUILD_POSTLOAD ALIEN_INSTALL_TYPE.

FUNCTIONS

alienfile

my $build = alienfile;
my $build = alienfile q{ use alienfile ... };
my $build = alienfile filename => 'alienfile';

Create a Alien::Build instance from the given alienfile. The first two forms are abbreviations.

my $build = alienfile;
# is the same as
my $build = alienfile filename => 'alienfile';

and

my $build = alienfile q{ use alienfile ... };
# is the same as
my $build = alienfile source => q{ use alienfile ... };

Except for the second abbreviated form sets the line number before feeding the source into Alien::Build so that you will get diagnostics with the correct line numbers.

source

The source for the alienfile as a string. You must specify one of source or filename.

filename

The filename for the alienfile. You must specify one of source or filename.

root

The build root.

stage

The staging area for the build.

prefix

The install prefix for the build.

alienfile_ok

my $build = alienfile_ok;
my $build = alienfile_ok q{ use alienfile ... };
my $build = alienfile_ok filename => 'alienfile';
my $build = alienfile_ok $build;

Same as alienfile above, except that it runs as a test, and will not throw an exception on failure (it will return undef instead).

[version 1.49]

As of version 1.49 you can also pass in an already formed instance of Alien::Build. This allows you to do something like this:

subtest 'a subtest' => sub {
  my $build = alienfile q{ use alienfile; ... };
  alienfile_skip_if_missing_prereqs; # skip if alienfile prereqs are missing
  alienfile_ok $build;  # delayed pass/fail for the compile of alienfile
};

alienfile_skip_if_missing_prereqs

alienfile_skip_if_missing_prereqs;
alienfile_skip_if_missing_prereqs $phase;

Skips the test or subtest if the prereqs for the alienfile are missing. If $phase is not given, then either share or system will be detected.

alien_install_type_is

alien_install_type_is $type;
alien_install_type_is $type, $name;

Simple test to see if the install type is what you expect. $type should be one of system or share.

alien_download_ok

my $file = alien_download_ok;
my $file = alien_download_ok $name;

Makes a download attempt and test that a file or directory results. Returns the file or directory if successful. Returns undef otherwise.

alien_extract_ok

my $dir = alien_extract_ok;
my $dir = alien_extract_ok $archive;
my $dir = alien_extract_ok $archive, $name;
my $dir = alien_extract_ok undef, $name;

Makes an extraction attempt and test that a directory results. Returns the directory if successful. Returns undef otherwise.

alien_build_ok

my $alien = alien_build_ok;
my $alien = alien_build_ok $name;
my $alien = alien_build_ok { class => $class };
my $alien = alien_build_ok { class => $class }, $name;

Runs the download and build stages. Passes if the build succeeds. Returns an instance of Alien::Base which can be passed into alien_ok from Test::Alien. Returns undef if the test fails.

Options

class

The base class to use for your alien. This is Alien::Base by default. Should be a subclass of Alien::Base, or at least adhere to its API.

alien_build_clean

alien_build_clean;

Removes all files with the current build, except for the runtime prefix. This helps test that the final install won't depend on the build files.

alien_clean_install

alien_clean_install;

Runs $build->clean_install, and verifies it did not crash.

alien_checkpoint_ok

alien_checkpoint_ok;
alien_checkpoint_ok $test_name;

Test the checkpoint of a build.

alien_resume_ok

alien_resume_ok;
alien_resume_ok $test_name;

Test a resume a checkpointed build.

alien_rc

alien_rc $code;

Creates rc.pl file in a temp directory and sets ALIEN_BUILD_RC. Useful for testing plugins that should be called from ~/.alienbuild/rc.pl. Note that because of the nature of how the ~/.alienbuild/rc.pl file works, you can only use this once!

alien_subtest

alien_subtest $test_name => sub {
  ...
};

Clear the build object and clear the build object before and after the subtest.
