NAME
Test::Net::LDAP::Mock - A mock LDAP client with simulated search in memory
SYNOPSIS
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();
"Test::Net::LDAP::Mock" is a subclass of Test::Net::LDAP, which is a subclass of
Net::LDAP.
In the actual test code, "ldap_mockify" in Test::Net::LDAP::Util should be used to mock
all the "Net::LDAP" instances in your application code.
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);
mockify
Test::Net::LDAP::Mock->mockify(sub {
# CODE
});
Inside the code block (recursively), all the occurrences of "Net::LDAP::new" are replaced
by "Test::Net::LDAP::Mock::new".
Subclasses of "Net::LDAP" are also mockified. "Test::Net::LDAP::Mock" is inserted into
@ISA of each subclass, only within the context of "mockify".
See also: "ldap_mockify" in Test::Net::LDAP::Util.
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'.
mock_bind
Gets or sets a LDAP result code (and optionally a message) that will be used as a message
returned by a later "bind()" call.
use Net::LDAP::Constant qw(LDAP_INVALID_CREDENTIALS);
$ldap->mock_bind(LDAP_INVALID_CREDENTIALS);
$ldap->mock_bind(LDAP_INVALID_CREDENTIALS, 'Login failed');
# ...
my $mesg = $ldap->bind(...);
$mesg->code && die $mesg->error; #=> die('Login failed')
In the list context, it returns an array of the code and message. In the scalar context,
it returns the code only.
Alternatively, this method can take a callback subroutine:
$ldap->mock_bind(sub {
my $arg = shift;
# Validate $arg->{dn} and $arg->{password}, etc.
if (...invalid credentials...) {
return LDAP_INVALID_CREDENTIALS;
}
});
The callback can return a single value as the LDAP result code or an array in the form
"($code, $message)". If the callback returns nothing (or "undef"), it is regarded as
"LDAP_SUCCESS".
mock_password
Gets or sets the password for the simple password authentication with "bind()".
$ldap->mock_password('uid=test, dc=example, dc=com' => 'test_password');
# Caution: Passwords should usually *not* be hard-coded like this. Consider to load
# passwords from a config file, etc.
The passwords are stored with the entry node in the data tree.
Once this method is used, the "bind()" call will check the credentials whenever the
"password" parameter is passed. Anonymous binding and all the other authentication methods
are not affected.
mock_target
Gets or sets the target scheme://host:port to normalize the way for successive
"Test::Net::LDAP::Mock" objects to resolve the associated data tree.
It is useful when normalizing the target scheme://host:port for different combinations.
For example, if there are sub-domains (such as ldap1.example.com and ldap2.example.com)
that share the same data tree, the target host should be normalized to be the single
master server (such as ldap.example.com).
Test::Net::LDAP::Mock->mock_target('ldap.example.com');
Test::Net::LDAP::Mock->mock_target('ldap.example.com', port => 3389);
Test::Net::LDAP::Mock->mock_target(['ldap.example.com', {port => 3389}]);
Test::Net::LDAP::Mock->mock_target({scheme => 'ldaps', port => 3389});
Since this will affect all the successive calls to instantiate "Test::Net::LDAP::Mock", it
may not be ideal when your application uses connections to multiple LDAP servers. In that
case, you can specify a callback that will be invoked each time a "Test::Net::LDAP::Mock"
object is instantiated.
Test::Net::LDAP::Mock->mock_target(sub {
my ($host, $arg) = @_;
# Normalize $host, $arg->{port}, and $arg->{scheme}
$host = 'ldap.example1.com' if $host =~ /\.example1\.com$/;
$host = 'ldap.example2.com' if $host =~ /\.example2\.com$/;
return ($host, $arg);
});
search
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
Returns an expected result message if the bind result has previously been setup by the
"mock_bind()" method. Otherwise, a success message is returned.
unbind
Returns a success message.
abandon
Returns a success message.
