Type::Tiny::Manual::UsingWithTestMore - phpMan

NAME
    Type::Tiny::Manual::UsingWithTestMore - Type::Tiny for test suites

MANUAL
  Test::TypeTiny
    This is a module for testing that types you've defined accept and reject
    the values you think they should.

     should_pass($value, $type);
     should_fail($othervalue, $type);

    Easy. (But yeah, I always forget whether the type goes first or second!)

    There's also a function to test that subtype/supertype relationships are
    working okay.

     ok_subtype($type, @subtypes);

    Of course you can just check a type like this:

     ok( $type->check($value) );

    But the advantage of "should_pass" is that if the "EXTENDED_TESTING"
    environment variable is set to true, "should_pass" will also perform a
    strict check on the value, which involves climbing up the type's
    inheritance tree (its parent, its parent's parent, etc) to make sure the
    value passes all their constraints.

    If a normal check and strict check differ, this is usually a problem in
    the inlining code somewhere.

    See Test::TypeTiny for more information.

  Type::Tiny as a Replacement for Test::Deep
    Here's one of the examples from the Test::Deep documentation:

     my $name_re = re('^(Mr|Mrs|Miss) \w+ \w+$');
     cmp_deeply(
       $person,
       {
         Name       => $name_re,
         Phone      => re('^0d{6}$'),
         ChildNames => array_each($name_re)
       },
       "person ok"
     );

    It's pretty easy to rewrite this to use Types::Standard:

     my $name = StrMatch[ qr/^(Mr|Mrs|Miss) \w+ \w+$/ ];
     should_pass(
       $person,
       Dict[
         Name         => $name,
         Phone        => StrMatch[ qr/^0d{6}$/ ],
         ChildNames   => ArrayRef[$name]
       ]
     );

    There's nothing especially wrong with Test::Deep, but if you're already
    familiar with Type::Tiny's built-in types and you've maybe written your
    own type libraries too, it will save you having to switch between using
    two separate systems of checks.
