Hello fellow Perl-Monks,

I am expanding my knowledge in testing right now. I want to test some functions of mine which interact with an LDAP-Server.

This might sound like a stupid question, but what is the best way to deal with Wrapper-Classes?

Context:
I write a module, which gets some Users from LDAP.
To communicate with the LDAP, I use a provided module from my workplace which wraps some system-specific parameters in the LDAP-methods (Utils::Ldap::CompanyLdap) and provides some additional methods.
This module again is a subclass of another LDAP-Wrapper Module (Utils::Ldap::Base) which finally uses Net::LDAP.

Now, in my program I use the first Ldap-Module e.g. 
package MyAwesomeProgram;
use Utils::Ldap::CompanyLdap;

sub read_users {
   # code that reads users from Ldap
   # searchGetEntries/get_value is provided by Utils::Ldap::CompanyLda
+p
   foreach my $entry ( $ldap->searchGetEntries() ) {
      my $uid = $entry->get_value( 'uid' );
      #... do something more
   }

}

I want to test the read_users function of my program, which gets its users via Utils::Ldap::CompanyLdap. How do I mock this? As you see, I do not directly interact with a Net::LDAP-Object

I have already understood that there is Test::Net::LDAP::Mock/Test::Net::LDAP::Utils qw(ldap_mockify) which can mock an Ldap Connection. What I do not understand yet: How can I use this in conjunction with my Wrapper Module? My module uses the code and the functions of our Ldap-Wrappers. Would the correct way be to write mocking code for the wrappers (e.g. Utils::Ldap::CompanyLdap::Mock), or is there a way of overwriting the Net::LDAP Object which is used by the Base-Wrapper Class Utils::Ldap::Base? I am not shure how to best approach this.

Second Question:
In case I get this working, is there a way of taking a Net::LDAP object and feeding it into my Mock-Object? I'd like to copy the datastructe of our LDAP to the Mock-Object.

Kind regards,

yulivee
