NAME

       Test::File::ShareDir - Create a Fake ShareDir for your modules for testing.

VERSION

       version 1.001002

SYNOPSIS

           use Test::More;

           # use FindBin; optional

           use Test::File::ShareDir
               # -root => "$FindBin::Bin/../" # optional,
               -share => {
                   -module => { 'My::Module' => 'share/MyModule' }
                   -dist   => { 'My-Dist'    => 'share/somefolder' }
               };

           use My::Module;

           use File::ShareDir qw( module_dir dist_dir );

           module_dir( 'My::Module' ) # dir with files from $dist/share/MyModule

           dist_dir( 'My-Dist' ) # dir with files from $dist/share/somefolder

DESCRIPTION

       "Test::File::ShareDir" is some low level plumbing to enable a distribution to perform
       tests while consuming its own "share" directories in a manner similar to how they will be
       once installed.

       This allows "File::ShareDir" to see the latest version of content instead of simply
       whatever is installed on whichever target system you happen to be testing on.

       Note: This module only has support for creating 'new' style share dirs and are NOT
       compatible with old File::ShareDirs.

       For this reason, unless you have File::ShareDir 1.00 or later installed, this module will
       not be usable by you.

SIMPLE INTERFACE

       Starting with version 0.4.0, there are a few extra interfaces you can use.

       These will probably be more useful, and easier to grok, because they don't have a layer of
       indirection in order to simultaneously support both "Module" and "Dist" "ShareDir"'s.

   Simple Exporter Interfaces
       "Test::File::ShareDir::Dist"

       "Test::File::ShareDir::Dist" provides a simple export interface for making "TempDir"
       "ShareDir"'s from a given path:

           use Test::File::ShareDir::Dist { "Dist-Name" => "share/" };

       This will automatically create a "ShareDir" for "Dist-Name" in a "TempDir" based on the
       contents of "CWD/share/"

       See "Test::File::ShareDir::Dist" for details.

       "Test::File::ShareDir::Module"

       "Test::File::ShareDir::Module" provides a simple export interface for making "TempDir"
       "ShareDir"'s from a given path:

           use Test::File::ShareDir::Module { "Module::Name" => "share/" };

       This will automatically create a "ShareDir" for "Module::Name" in a "TempDir" based on the
       contents of "CWD/share/"

       See "Test::File::ShareDir::Module" for details.

   Simple Object Oriented Interfaces
       "Test::File::ShareDir::Object::Dist"

       "Test::File::ShareDir::Object::Dist" provides a simple object oriented interface for
       making "TempDir" "ShareDir"'s from a given path:

           use Test::File::ShareDir::Object::Dist;

           my $obj = Test::File::ShareDir::Object::Dist->new( dists => { "Dist-Name" => "share/" } );
           $obj->install_all_dists;
           $obj->register;

       This will automatically create a "ShareDir" for "Dist-Name" in a "TempDir" based on the
       contents of "CWD/share/"

       See "Test::File::ShareDir::Object::Dist" for details.

       "Test::File::ShareDir::Object::Module"

       "Test::File::ShareDir::Object::Module" provides a simple object oriented interface for
       making "TempDir" "ShareDir"'s from a given path:

           use Test::File::ShareDir::Object::Module;

           my $obj = Test::File::ShareDir::Object::Module->new( modules => { "Module::Name" => "share/" } );
           $obj->install_all_modules;
           $obj->register;

       This will automatically create a "ShareDir" for "Module::Name" in a "TempDir" based on the
       contents of "CWD/share/"

       See "Test::File::ShareDir::Object::Module" for details.

SCOPE LIMITED UTILITIES

       "Test::File::ShareDir" provides a few utility functions to aide in temporarily adjusting
       "ShareDir" behavior.

           use Test::File::ShareDir qw( with_dist_dir with_module_dir );

           with_dist_dir({ 'Dist-Name' => 'Some/Path' }, sub {
             # dist_dir() now behaves differently here
           });
           with_module_dir({ 'Module::Name' => 'Some/Path' }, sub {
             # module_dir() now behaves differently here
           });

       See "EXPORTABLE FUNCTIONS" for details.

IMPORTING

       Since 1.001000, there are 2 ways of passing arguments to "import"

         use Foo { -root => ... options }, qw( functions to import );
         use Foo -optname => option, -optname => option, qw( functions to import );

       Both should work, but the former might be less prone to accidental issues.

   IMPORT OPTIONS
       -root

       This parameter is the prefix the other paths are relative to.

       If this parameter is not specified, it defaults to the Current Working Directory ( "CWD"
       ).

       In versions prior to 0.3.0, this value was mandatory.

       The rationale behind using "CWD" as the default value is as follows.

       •   Most users of this module are likely to be using it to test distributions

       •   Most users of this module will be using it in "$project/t/" to load files from
           "$project/share/"

       •   Most "CPAN" tools run tests with "CWD" = $project

       Therefor, defaulting to "CWD" is a reasonably sane default for most people, but where it
       is not it can still be overridden.

         -root => "$FindBin::Bin/../" # resolves to project root from t/ regardless of Cwd.

       -share

       This parameter is mandatory, and contains a "hashref" containing the data that explains
       what directories you want shared.

         -share =>  { ..... }

       -module

       "-module" contains a "hashref" mapping Module names to path names for module_dir style
       share dirs.

         -share => {
           -module => { 'My::Module' => 'share/mymodule/', }
         }

         ...

         module_dir('My::Module')

       Notedly, it is a "hashref", which means there is a limitation of one share dir per module.
       This is simply because having more than one share dir per module makes no sense at all.

       -dist

       "-dist" contains a "hashref" mapping Distribution names to path names for dist_dir style
       share dirs. The same limitation applied to "-module" applies here.

         -share => {
           -dist => { 'My-Dist' => 'share/mydist' }
         }
         ...
         dist_dir('My-Dist')

EXPORTABLE FUNCTIONS

   with_dist_dir
       Sets up a "ShareDir" environment with limited context.

         # with_dist_dir(\%config, \&sub);
         with_dist_dir( { 'Dist-Name' => 'share/' } => sub {

             # File::ShareDir resolves to a copy of share/ in this context.

         } );

       %config can contain anything "Test::File::ShareDir::Dist" accepts.

       "-root": Defaults to $CWD
       "$distName": Declare $distName's "ShareDir".

       Since 1.001000

   with_module_dir
       Sets up a "ShareDir" environment with limited context.

         # with_module_dir(\%config, \&sub);
         with_module_dir( { 'Module::Name' => 'share/' } => sub {

             # File::ShareDir resolves to a copy of share/ in this context.

         } );

       %config can contain anything "Test::File::ShareDir::Module" accepts.

       "-root": Defaults to $CWD
       "$moduleName": Declare $moduleName's "ShareDir".

       Since 1.001000

       Thanks to the "#distzilla" crew for ideas,suggestions, code review and debugging, even
       though not all of it made it into releases.
