NAME

Test::Builder::Mock::Class - Simulating other classes for Test::Builder

SYNOPSIS

use Test::Builder::Mock::Class ':all';
mock_class 'Net::FTP' => 'Net::FTP::Mock';
my $mock_object = Net::FTP::Mock->new;

# anonymous mocked class
my $metamock = mock_anon_class 'Net::FTP';
my $mock_object = $metamock->new_object;

DESCRIPTION

This module adds support for standard Test::Builder framework (Test::Simple or Test::More) to Test::Mock::Class.

Mock class can be used to create mock objects which can simulate the behavior of complex, real (non-mock) objects and are therefore useful when a real object is impractical or impossible to incorporate into a unit test.

INHERITANCE

FUNCTIONS

mock_class( class : Str, mock_class : Str = undef ) : Moose::Meta::Class

Creates the concrete mock class based on original class. If the name of mock_class is undefined, its name is created based on name of original class with added ::Mock suffix.

The function returns the metaclass object of new mock_class.

mock_anon_class( class : Str ) : Moose::Meta::Class

Creates an anonymous mock class based on original class. The name of this class is automatically generated.

The function returns the metaobject of new mock class.

IMPORTS

Test::Builder::Mock::Class ':all';

Imports all functions into caller's namespace.

EXAMPLE

The Test::Builder::Mock::Class fits perfectly to Test::Builder (Test::Simple or Test::More) tests. It adds automatically the tests for each mock_invoke (which is called implicitly by all mock methods) and mock_tally. It means that you need to add these tests to your test plan.

Example code:

package My::ExampleTest;

use Test::More tests => 3;
use Test::Builder::Mock::Class ':all';

my $mock = mock_anon_class 'IO::File';
my $io = $mock->new_object;
$io->mock_return( open => 1, args => [qr//, 'r'] );

ok( $io->open('/etc/passwd', 'r'), '$io->open' );
$io->mock_tally;

BUGS

The API is not stable yet and can be changed in future.
