=head1 NAME

Test::DocKnot::Spin - Helper functions for testing spin

=head1 SYNOPSIS

    use Test::DocKnot::Spin qw(is_spin_output);

    $spin->spin_file($input, $output);
    is_spin_output($output, $expected, 'Check a single file');

    $spin->spin_tree($input_path, $output_path);
    is_spin_output_tree($output_path, $expected_path, 'Check a tree');

=head1 DESCRIPTION

This module collects utility functions that are useful for testing the
App::DocKnot::Spin module.

This module B<must> be loaded before Test::More or it will abort during
import.

=head1 FUNCTIONS

None of these functions are imported by default.  The ones used by a script
should be explicitly imported.

=over 4

=item fix_pointers(TREE, BASE)

Find all F<*.spin> pointer files in TREE, treat any relative paths found in
those pointer files as if they were relative to BASE, convert them to absolute
paths, and write out the modified pointer file.  This is intended to be used
after copying an input tree for App::DocKnot::Spin to a temporary directory,
which would otherwise break any relative paths in pointer files.

=item is_spin_output(OUTPUT, EXPECTED, MESSAGE)

Given OUTPUT, which should be a Path::Tiny object pointing to the output from
App::DocKnot::Spin, compare it to the expected output in the file named
EXPECTED (also a Path::Tiny object).  MESSAGE is the message to print with the
test results for easy identification.

=item is_spin_output_tree(OUTPUT, EXPECTED, MESSAGE)

Compare the output tree at OUTPUT with the expected output tree at EXPECTED
(both Path::Tiny objects), using the same comparison algorithm as
is_spin_output() for HTML and RSS files and a straight content comparison for
all other files.  MESSAGE with the message to print with the test results for
easy identification.
