The FakeChat notifier transport can be used for testing purposes, as it does not require third party setup.

INFO

Notifier Chat Channel's own test code uses the Fake transport to mock the behavior of transports.

Send messages to logs or email

This transport sends chat messages to either logs or email.

For logger, you can view them in dblog.module or your configured logging solution, such as a logger for Monolog.

For email, messages will be transformed into email, so you can view them in a third party or a local development solution like Mailpit or Mailhog.

Installation

From a project with a pre-installed version of Notifier and Notifier Chat Channel, bring in the FakeChat dependency:

composer require symfony/fake-chat-notifier

WARNING

The dependency must be brought in as a non- dev requirement, as the container compiler pass (\Drupal\notifier_chat_channel\NotifierChatChannelCompilerPass) is intelligent enough to not enable services for transports when they're found in require-dev.

Configuration

In the site directory, usually sites/default/, create a services.yml file.

Add to settings.php:

$settings['container_yamls'][] = __DIR__ . '/services.yml';

The transport DSN is different depending on whether you prefer email or logger behavior. Add to services.yml:

parameters:
  chatter.transports:
    # Choose one of, logger:
    fake_transport_logger: 'fakechat+logger://default'
    # ...or email:
    fake_transport_email: 'fakechat+email://MAILER_SERVICE_ID?to=TO&from=FROM'

Then clear Drupal caches:

drush cr
