NAME

Test::Moose::More - More tools for testing Moose packages

VERSION

This document describes version 0.023 of Test::Moose::More - released January 21, 2014 as part of Test-Moose-More.

SYNOPSIS

use Test::Moose::More;

is_class 'Some::Class';
is_role  'Some::Role';
has_method_ok 'Some::Class', 'foo';

# ... etc

DESCRIPTION

This package contains a number of additional tests that can be employed against Moose classes/roles. It is intended to replace Test::Moose in your tests, and re-exports any tests that it has and we do not, yet.

FUNCTIONS

known_sugar

Returns a list of all the known standard Moose sugar (has, extends, etc).

TEST_FUNCTIONS

meta_ok $thing

Tests $thing to see if it has a metaclass; $thing may be the class name or instance of the class you wish to check.

does_ok $thing, < $role | \@roles >, [ $message ]

Checks to see if $thing does the given roles. $thing may be the class name or instance of the class you wish to check.

Note that the message will be taken verbatim unless it contains %s somewhere; this will be replaced with the name of the role being tested for.

does_not_ok $thing, < $role | \@roles >, [ $message ]

Checks to see if $thing does not do the given roles. $thing may be the class name or instance of the class you wish to check.

Note that the message will be taken verbatim unless it contains %s somewhere; this will be replaced with the name of the role being tested for.

has_attribute_ok $thing, $attribute_name, [ $message ]

Checks $thing for an attribute named $attribute_name; $thing may be a class name, instance, or role name.

has_method_ok $thing, @methods

Queries $thing's metaclass to see if $thing has the methods named in @methods.

requires_method_ok $thing, @methods

Queries $thing's metaclass to see if $thing requires the methods named in @methods.

Note that this really only makes sense if $thing is a role.

is_role $thing

Passes if $thing's metaclass is a Moose::Meta::Role.

is_class $thing

Passes if $thing's metaclass is a Moose::Meta::Class.

is_anon $thing

Passes if $thing is "anonymous".

is_not_anon $thing

Passes if $thing is not "anonymous".

check_sugar_removed_ok $thing

Ensures that all the standard Moose sugar is no longer directly callable on a given package.

check_sugar_ok $thing

Checks and makes sure a class/etc can still do all the standard Moose sugar.

validate_thing

Runs a bunch of tests against the given $thing, as defined:

validate_class $thing => (

    attributes => [ ... ],
    methods    => [ ... ],
    isa        => [ ... ],

    # ensures $thing does these roles
    does       => [ ... ],

    # ensures $thing does not do these roles
    does_not   => [ ... ],
);

$thing can be the name of a role or class, an object instance, or a metaclass.

validate_role

The same as validate_thing(), but ensures $thing is a role, and allows for additional role-specific tests.

validate_role $thing => (

    required_methods => [ ... ],

    # ...and all other options from validate_thing()

validate_class

The same as validate_thing(), but ensures $thing is a class, and allows for additional class-specific tests.

validate_attribute

validate_attribute() allows you to test how an attribute looks once built and attached to a class.

Let's say you have an attribute defined like this:

has foo => (
    traits  => [ 'TestRole' ],
    is      => 'ro',
    isa     => 'Int',
    builder => '_build_foo',
    lazy    => 1,
);

You can use validate_attribute() to ensure that it's built out in the way you expect:

validate_attribute TestClass => foo => (
    -does => [ 'TestRole' ],
    -isa  => [ 'Moose::Meta::Attribute' ], # for demonstration's sake
    traits   => [ 'TestRole' ],
    isa      => 'Int',
    does     => 'Bar',
    handles  => { },
    reader   => 'foo',
    builder  => '_build_foo',
    default  => undef,
    init_arg => 'foo',
    lazy     => 1,
    required => undef,
);

Not yet documented or tested exhaustively; please see t/validate_attribute.t for details at the moment. This test routine is likely to change in implementation and scope, with every effort to maintain backwards compatibility.

attribute_options_ok

Validates that an attribute is set up as expected; like validate_attribute(), but only concerns itself with attribute options.

Not yet documented or tested exhaustively; please see t/validate_attribute.t for details at the moment. This test routine is likely to change in implementation and scope, with every effort to maintain backwards compatibility.
