To be able to test pqMessenger it is necessary to have in addition to the installation of the application itself:

• An OpenLDAP server installation + pqChecker plug-in on the same server machine
• A functional installation of a MoM, e.g. Apache ActiveMQ Artemis
• At least one valid person entry in the OpenLDAP server to test passwords broadcast
• A way to send and receive messages from the MoM (Apache Artemis provided an optional interface that allows it)

Set up the settings:

• The MoM:
  • Create a Topic called PwdChannel and a test user who has read and write rights to this Topic.
  • Set the MoM logs to a sufficient level to monitor the flow of messages
• pqMessenger: customize the «pqmessenger.yml» file for the test
• Parameter servers: a single server, set host and port to the values used for the MoM (e.g. localhost and 61614)
• login and password parameters: set to the values of the MoM test user, see the MoM parameter setting above
• activetls parameter: set to false to disable TLS and make the test easier to perform
• pqMessenger logs: Set the log level to «debug» in the file «log4j2.xml»

The pqMessenger configuration files must be in the «/etc/ldap/pqchecker/» folder for a Debian compliant system and «/etc/openldap/pqchecker/» for a Redhat compliant system.

A test that include the entire functional features of the communication performed by pqMessenger will proceed as follows:

1. Start the MoM, then pqMessenger. Check the success of connection to the MoM in the pqmessenger logs: /var/log/pqmessenger/pqmessenger.log
2. Create a subscription to the PwdChannel Topic of the MoM
3. Send a message to read the passwords quality parameters and check the response message
4. Send a message to change the passwords quality parameters. Check that these parameters have actually been modified: contents of the pqparams.dat file
5. Modify the password of a person contained in the directory. Check in the MoM logs that the broadcast message for this password has been sent
