NAME
    Test::TypeConstraints - testing whether some value is valid as
    (Moose|Mouse)::Meta::TypeConstraint

SYNOPSIS
      use Test::TypeConstraints qw(type_isa);

      type_isa($got, "ArrayRef[Int]", "type should be ArrayRef[Int]");

DESCRIPTION
    Test::TypeConstraints is for testing whether some value is valid as
    (Moose|Mouse)::Meta::TypeConstraint.

METHODS
  type_isa
        type_isa($value, $type);
        type_isa($value, $type, $test_name);
        type_isa($value, $type, $test_name, %options);

    Performs a type check against the $value using the $type.

    $type can be a class name, a Moose/Mouse type name,
    Moose/Mouse::Meta::TypeConstraint object or
    Moose/Mouse::Meta::TypeConstraint::Class object.

    $test_name is the description of the test. If not given, one will be
    provided.

    %options control optional behaviors. Its keys can be the following...

   coerce
    If true, coercion will be used when performing the type check.

    If a code ref is given, it will be run and passed in the coerced value
    for additional testing.

        type_isa $value, "Some::Class", "coerce to Some::Class", coerce => sub {
            isa_ok $_[0], "Some::Class";
            is $_[0]->value, $value;
        };

  type_does
        type_does($value, $role);
        type_does($value, $role, $test_name);
        type_does($value, $role, $test_name, %options);

    Tests that the $value does the $role.

    Works like "type_isa", but for roles instead of classes and types. The
    $value must have consumed the given $role.

  type_isnt
  type_doesnt
    The opposites of "type_isa" and "type_does". They take the same
    arguments and options.

    Checks that the value is *not* of the given type or role.
