NAME

Test::CompanionClasses::Base - base class for test companion classes

SYNOPSIS

package My::Foo_TEST;

use warnings;
use strict;

use base 'Test::CompanionClasses::Base';

use constant PLAN => 5;

sub run {
    my $self = shift;
    $self->SUPER::run(@_);
    is_deeply(...);
    ...
}

DESCRIPTION

Base class for test companion classes. Each test companion class should inherit from this class.

METHODS

new

A constructor per Class::Accessor::Complex's mk_new().

package

Automatically set; holds the package name of the class you are testing. If your test companion class is called My::Foo_TEST, then package() will return My::Foo.

An accessor per Class::Accessor::Complex's mk_scalar_accessor().

PLAN

A constant that says how many tests this particular class defines. Real test companion classes (i.e., subclasses of this class) will want to redefine it like this:

use constant PLAN => 5;

Note that you should only specify how many tests the current class runs; test counts of superclasses are automatically taken care of.

planned_test_count

Uses PLAN(), calculated over the test companion class' whole class hierarchy, to determine how many tests will be run in total.

make_real_object

Loads the actual class being tested (cf. package()) and returns an object of this class (constructed by calling new() on it).

In your test companion class you will want to test certain assumptions about your real class, so this method will be useful.

run

Test companion classes should override this method and run their tests. Be sure to call SUPER::run(@_) so that all tests over the class hierarchy are run.

The run() method in this base class just prints a line informing the test user that tests for this particular companion class have begun. If you have several companion classes - and you probably will or you won't have been using Test::CompanionClasses - this serves as a visual distinction of where on companion class' tests end the next ones' begin.
