=head1 NAME
Test::Alien::Build - Tools for testing Alien::Build + alienfile
=head1 VERSION
version 2.29
=head1 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;
=head1 DESCRIPTION
This module provides some tools for testing L<Alien::Build> and L<alienfile>. Outside of L<Alien::Build>
core development, It is probably most useful for L<Alien::Build::Plugin> developers.
This module also unsets a number of L<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:
C<ALIEN_BUILD_PRELOAD> C<ALIEN_BUILD_POSTLOAD> C<ALIEN_INSTALL_TYPE>.
=head1 FUNCTIONS
=head2 alienfile
my $build = alienfile;
my $build = alienfile q{ use alienfile ... };
my $build = alienfile filename => 'alienfile';
Create a Alien::Build instance from the given L<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 L<Alien::Build>
so that you will get diagnostics with the correct line numbers.
=over 4
=item source
The source for the alienfile as a string. You must specify one of C<source> or C<filename>.
=item filename
The filename for the alienfile. You must specify one of C<source> or C<filename>.
=item root
The build root.
=item stage
The staging area for the build.
=item prefix
The install prefix for the build.
=back
=head2 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 C<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 L<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
};
=head2 alienfile_skip_if_missing_prereqs
alienfile_skip_if_missing_prereqs;
alienfile_skip_if_missing_prereqs $phase;
Skips the test or subtest if the prereqs for the alienfile are missing.
If C<$phase> is not given, then either C<share> or C<system> will be
detected.
=head2 alien_install_type_is
alien_install_type_is $type;
alien_install_type_is $type, $name;
Simple test to see if the install type is what you expect.
C<$type> should be one of C<system> or C<share>.
=head2 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 C<undef> otherwise.
=head2 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 C<undef> otherwise.
=head2 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 }, $name;
Runs the download and build stages. Passes if the build succeeds. Returns an instance
of L<Alien::Base> which can be passed into C<alien_ok> from L<Test::Alien>. Returns
C<undef> if the test fails.
Options
=over 4
=item class
The base class to use for your alien. This is L<Alien::Base> by default. Should
be a subclass of L<Alien::Base>, or at least adhere to its API.
=back
=head2 alien_build_clean
alien_build_clean;
Removes all files with the current build, except for the runtime prefix.
This helps test that the final install won't depend on the build files.
=head2 alien_clean_install
alien_clean_install;
Runs C<$build-E<gt>clean_install>, and verifies it did not crash.
=head2 alien_checkpoint_ok
alien_checkpoint_ok;
alien_checkpoint_ok $test_name;
Test the checkpoint of a build.
=head2 alien_resume_ok
alien_resume_ok;
alien_resume_ok $test_name;
Test a resume a checkpointed build.
=head2 alien_rc
alien_rc $code;
Creates C<rc.pl> file in a temp directory and sets ALIEN_BUILD_RC. Useful for testing
plugins that should be called from C<~/.alienbuild/rc.pl>. Note that because of the
nature of how the C<~/.alienbuild/rc.pl> file works, you can only use this once!
=head2 alien_subtest
alien_subtest $test_name => sub {
...
};
Clear the build object and clear the build object before and after the subtest.
