NAME

Test::Net::LDAP::Mock - A mock LDAP client with simulated search in memory

SYNOPSIS

Test::Net::LDAP::Mock is a subclass of Test::Net::LDAP, which is a subclass of Net::LDAP. All the LDAP operations are performed in memory, instead of connecting to the real LDAP server.

use Test::Net::LDAP::Mock;
my $ldap = Test::Net::LDAP::Mock->new();

In practice, it is recommended to use "ldap_mockify" in Test::Net::LDAP::Util as below.

use Test::More tests => 1;
use Test::Net::LDAP::Util qw(ldap_mockify);

ldap_mockify {
    # Anywhere in this block, all the occurrences of Net::LDAP::new are
    # replaced by Test::Net::LDAP::Mock::new
    ok my_application_routine();
};

Note: if no LDAP entries have been added to the in-memory directory, the search method will silently succeed with no entries found.

Below is an example to set up some fake data for particular test cases.

use Test::More tests => 1;
use Test::Net::LDAP::Util qw(ldap_mockify);

ldap_mockify {
    my $ldap = Net::LDAP->new('ldap.example.com');
    
    $ldap->add('uid=user1, ou=users, dc=example, dc=com');
    $ldap->add('uid=user2, ou=users, dc=example, dc=com');
    $ldap->add('cn=group1, ou=groups, dc=example, dc=com', attrs => [
        member => [
            'uid=user1, ou=users, dc=example, dc=com',
            'uid=user2, ou=users, dc=example, dc=com',
        ]
    ]);
    
    ok my_application_routine();
};

Test::Net::LDAP::Mock maintains a shared LDAP directory tree for the same host/port, while it separates the directory trees for different host/port combinations. Thus, it is important to specify a correct server location consistently.

DESCRIPTION

Overview

Test::Net::LDAP::Mock provides all the operations of Net::LDAP, while they are performed in memory with fake data that are set up just for testing.

It is most useful for developers who write testing for an application that uses LDAP search, while they do not have full control over the organizational LDAP server. In many cases, developers do not have write access to the LDAP data, and the organizational information changes over time, which makes it difficult to write stable test cases with LDAP. Test::Net::LDAP::Mock helps developers set up any fake LDAP directory tree in memory, so that they can test sufficient varieties of senarios for the application.

Without this module, an alternative way to test an application using LDAP is to run a real server locally during testing. (See how Net::LDAP is tested with a local OpenLDAP server.) However, it may not be always trivial to set up such a server with correct configurations and schemas, where this module makes testing easier.

LDAP Schema

In the current version, the LDAP schema is ignored when entries are added or modified, although a schema can optionally be specified only for the search filter matching (based on Net::LDAP::FilterMatch).

An advantage is that it is much easier to set up fake data with any arbitrary LDAP attributes than to care about all the restrictions with the schema. A disadvantage is that it cannot test schema-sensitive cases.

Controls

LDAPv3 controls are not supported (yet). The control parameter given as an argument of a method will be ignored.

METHODS

new

Creates a new object. It does not connect to the real LDAP server. Each object is associated with a shared LDAP data tree in memory, depending on the target (host/port/path) and scheme (ldap/ldaps/ldapi).

Test::Net::LDAP::Mock->new();
Test::Net::LDAP::Mock->new('ldap.example.com', port => 3389);

mock_data

Retrieves the currently associated data tree (for the internal purpose only).

mock_schema

Gets or sets the LDAP schema (Net::LDAP::Schema object) for the currently associated data tree.

In this version, the schema is used only for the search filter matching (based on Net::LDAP::FilterMatch internally). It has no effect for any modification operations such as add, modify, and delete.

mock_root_dse

Gets or sets the root DSE (Net::LDAP::RootDSE) for the currently associated data tree.

This should be set up as part of the test fixture before any successive call to the root_dse() method, since Net::LDAP will cache the returned object.

$ldap->mock_root_dse(
    namingContexts => 'dc=example,dc=com'
);

Note: the namingContexts value has no effect on the restriction with the topmost DN. In other words, even if namingContexts is set to 'dc=example,dc=com', the add() method still allows you to add an entry to 'dc=somewhere-else'.

Searches for entries in the currently associated data tree.

$ldap->search(
    base => 'dc=example, dc=com', scope => 'sub',
    filter => '(cn=*)', attrs => ['uid', 'cn']
);

See "search" in Net::LDAP for more parameter usage.

compare

Compares an attribute/value pair with an entry in the currently associated data tree.

$ldap->compare('uid=test, dc=example, dc=com',
    attr => 'cn',
    value => 'Test'
);

See "compare" in Net::LDAP for more parameter usage.

add

Adds an entry to the currently associated data tree.

$ldap->add('uid=test, dc=example, dc=com', attrs => [
    cn => 'Test'
]);

See "add" in Net::LDAP for more parameter usage.

modify

Modifies an entry in the currently associated data tree.

$ldap->modify('uid=test, dc=example, dc=com', add => [
    cn => 'Test2'
]);

See "modify" in Net::LDAP for more parameter usage.

delete

Deletes an entry from the currently associated data tree.

$ldap->delete('uid=test, dc=example, dc=com');

See "delete" in Net::LDAP for more parameter usage.

moddn

Modifies DN of an entry in the currently associated data tree.

$ldap->moddn('uid=test, dc=example, dc=com',
    newrdn => 'uid=test2'
);

See "moddn" in Net::LDAP for more parameter usage.

bind

Does nothing except for returning a success message.

unbind

Does nothing except for returning a success message.

abandon

Does nothing except for returning a success message.
