NAMEType::Tiny::Manual::UsingWithTestMore − Type::Tiny for test suites
MANUAL
Test::TypeTinyThis 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::DeepHere'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.
NEXT STEPSHere's your next step: • Type::Tiny::Manual::Params Advanced information on Type::Params, and using Type::Tiny with other signature modules like Function::Parameters and Kavorka.
