I am going to start writing tests for my Fancy::Open module that needs a file to open. Test::MockObject was suggested. In reading the beginning of the documentation, I saw it can mock arrays, scalars, code, and globs, but I do not see files.

my $mock_array  = Test::MockObject->new( [] );
my $mock_scalar = Test::MockObject->new( \( my $scalar ) );
my $mock_code   = Test::MockObject->new( sub {} );
my $mock_glob   = Test::MockObject->new( \*GLOB );

So, can Test::MockObject mock a file? If yes, how does it work? I am having a difficult time understanding the documentation.
