## NAME
    [Type::Tiny::Manual::UsingWithTestMore](https://www.chedong.com/phpMan.php/perldoc/Type%3A%3ATiny%3A%3AManual%3A%3AUsingWithTestMore/markdown) - [Type::Tiny](https://www.chedong.com/phpMan.php/perldoc/Type%3A%3ATiny/markdown) for test suites

## MANUAL
### [Test::TypeTiny](https://www.chedong.com/phpMan.php/perldoc/Test%3A%3ATypeTiny/markdown)
    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](https://www.chedong.com/phpMan.php/perldoc/Test%3A%3ATypeTiny/markdown) for more information.

### [Type::Tiny](https://www.chedong.com/phpMan.php/perldoc/Type%3A%3ATiny/markdown) as a Replacement for [Test::Deep](https://www.chedong.com/phpMan.php/perldoc/Test%3A%3ADeep/markdown)
    Here's one of the examples from the [Test::Deep](https://www.chedong.com/phpMan.php/perldoc/Test%3A%3ADeep/markdown) 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](https://www.chedong.com/phpMan.php/perldoc/Types%3A%3AStandard/markdown):

     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](https://www.chedong.com/phpMan.php/perldoc/Test%3A%3ADeep/markdown), but if you're already familiar with
    [Type::Tiny](https://www.chedong.com/phpMan.php/perldoc/Type%3A%3ATiny/markdown)'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.

        Advanced information on [Type::Params](https://www.chedong.com/phpMan.php/perldoc/Type%3A%3AParams/markdown), and using [Type::Tiny](https://www.chedong.com/phpMan.php/perldoc/Type%3A%3ATiny/markdown) with other signature modules like
        [Function::Parameters](https://www.chedong.com/phpMan.php/perldoc/Function%3A%3AParameters/markdown) and Kavorka.
