DESCRIPTION
"Test::Deep::Type" provides the sub "is_type" to indicate that the data being tested must validate against the passed type. This is an actual type object, not a string name --- for example something provided via MooseX::Types, or a plain old coderef that returns a bool (such as what might be used in a Moo type constraint).FUNCTIONS

"is_type"
Exported by default; to be used within a Test::Deep comparison function such as cmp_deeply. As this module aims to be a solution for many popular type systems, we attempt to use the type in multiple ways:
-
- MooseX::Types/Moose::Meta::TypeConstraint-style types:
- If the "validate" method exists, it is invoked on the type object with the data as its parameter (which should return "undef" on success, and the error message on failure).
- coderef/Moo-style types:
-
If the type appears to be or act like a coderef (either a coderef, blessed or
unblessed, or possesses a coderef overload) the type is invoked as a sub, with
the data as its parameter. Its return value is treated as a boolean; if it
also dies with a message describing the failure, this message is used in the
failure diagnostics.
Type::Tiny types fall into this category, and are fully supported.
-
CAVEATS
Regular strings describing a type under a particular system (e.g. Moose, Params::Validate) are not currently supported.SUPPORT
