add static tests for coercion functions?

[sherrardb]

similar to the test currently local.t

my $false =  bless( do{\(my $o = 0)}, 'JSON::PP::Boolean' );

  my $DATA = {
    'client_ip' => '138.197.111.110',
    'object' => 'token',
    'type' => 'card',
...
      'customer' => undef,
      'address_line1_check' => undef,
      'address_country' => undef
      }
  };

  Unexpected_keys_ignored: {
    my $obj =  Net::Stripe::_hash_to_object({
            %$DATA,
            'dummy_object' => {
              object  => 'foo_bar',
              garbage => 'bin',
            },
            dummy_scalar => 'rubbish',
    });
    is (ref($obj), 'Net::Stripe::Token', 'unmodelled data has no effect');
    ok (! exists($obj->{dummy_object}), 'dummy_object ignored');
    ok (! exists($obj->{dummy_scalar}), 'dummy_scalar ignored');
  }

we may want to add tests that confirm the expected behavior of _pre_2011_08_01_processing(),
_pre_2012_10_26_processing(), etc.

my testing has always involved forcing the API version with

    $req->header( 'Stripe-Version' => $ENV{STRIPE_API_VERSION} ) if exists( $ENV{STRIPE_API_VERSION} );

and iterating over a range of versions using a bash for loop, but obviously this method is of no benefit for users, cpantesters, etc.

[sherrardb]

methods used on the request side fall into this category as well. and we already have an example:

Placeholder: {
    my $return = { Net::Stripe::Resource::form_fields_for_hashref( "hashref", { level1=> { level2=> "value" } } ) };
    is_deeply $return, { 'hashref[level1][level2]' => 'value' };
}

that section just needs a name change to remove the implication of transience.
