NAME

       Test2::Tools::Exports - Tools for validating exporters.

DESCRIPTION

       These are tools for checking that symbols have been imported into your namespace.

SYNOPSIS

           use Test2::Tools::Exports

           use Data::Dumper;
           imported_ok qw/Dumper/;
           not_imported_ok qw/dumper/;

EXPORTS

       All subs are exported by default.

       imported_ok(@SYMBOLS)
           Check that the specified symbols exist in the current package. This will not find inherited subs.
           This will only find symbols in the current package's symbol table. This WILL NOT confirm that the
           symbols were defined outside of the package itself.

               imported_ok( '$scalar', '@array', '%hash', '&sub', 'also_a_sub' );

           @SYMBOLS can contain any number of symbols. Each item in the array must be a string. The string
           should be the name of a symbol. If a sigil is present then it will search for that specified type, if
           no sigil is specified it will be used as a sub name.

       not_imported_ok(@SYMBOLS)
           Check that the specified symbols do not exist in the current package. This will not find inherited
           subs. This will only look at symbols in the current package's symbol table.

               not_imported_ok( '$scalar', '@array', '%hash', '&sub', 'also_a_sub' );

           @SYMBOLS can contain any number of symbols. Each item in the array must be a string. The string
           should be the name of a symbol. If a sigil is present, then it will search for that specified type.
           If no sigil is specified, it will be used as a sub name.

CAVEATS

       Before Perl 5.10, it is very difficult to distinguish between a package scalar that is undeclared vs
       declared and undefined. Currently "imported_ok" and "not_imported_ok" cannot see package scalars declared
       using "our $var" unless the variable has been assigned a defined value.

       This will pass on recent perls, but fail on perls older than 5.10:

           use Test2::Tools::Exports;

           our $foo;

           # Fails on perl onlder than 5.10
           imported_ok(qw/$foo/);

       If $foo is imported from another module, or imported using "use vars qw/$foo/;" then it will work on all
       supported perl versions.

           use Test2::Tools::Exports;

           use vars qw/$foo/;
           use Some::Module qw/$bar/;

           # Always works
           imported_ok(qw/$foo $bar/);
