You should read man test and the definition of path, see example:
Code:
$ test -e /test/dir1/foo.bar && echo Path OK || echo Path OK
Path OK                     
$ test -d /test/dir1/foo.bar && echo Path OK || echo Path NOK
Path NOK              #that's wrong , the path exist , however it's not a directory (-d).

NAME
MouseX::Types::Path::Class - A Path::Class type library for Mouse SYNOPSIS
CLASS TYPES package MyApp; use Mouse; use MouseX::Types::Path::Class; has 'dir' => ( is => 'ro', isa => 'Path::Class::Dir', required => 1, coerce => 1, ); has 'file' => ( is => 'ro', isa => 'Path::Class::File', required => 1, coerce => 1, ); CUSTOM TYPES package MyApp; use Mouse; use MouseX::Types::Path::Class qw(Dir File); has 'dir' => ( is => 'ro', isa => Dir, required => 1, coerce => 1, ); has 'file' => ( is => 'ro', isa => File, required => 1, coerce => 1, ); DESCRIPTION
MouseX::Types::Path::Class creates common Mouse types, coercions and option specifications useful for dealing with Path::Class objects as Mouse attributes. Coercions (see Mouse::Util::TypeConstraints) are made from both "Str" and "ArrayRef" to both Path::Class::Dir and Path::Class::File objects. If you have MouseX::Getopt installed, the Getopt option type ("=s") will be added for both Path::Class::Dir and Path::Class::File. TYPES
Dir A Path::Class::Dir class type. Coerces from "Str" and "ArrayRef" via "new" in Path::Class::Dir. File A Path::Class::File class type. Coerces from "Str" and "ArrayRef" via "new" in Path::Class::File. AUTHOR
