README

A Symfony Bundle to use when you want to assert that messages used with Message brokers such like RabbitMQ are compliant with the Zero Downtime Deployment.

Upgrading from yousign/zdd-message-bundle

This bundle was published as yousign/zdd-message-bundle up to v3.3.0, under the Yousign\ZddMessageBundle\ namespace. Following the company rename to Youtrust, v4.0.0 moves to youtrust/zdd-message-bundle and the Youtrust\ZddMessageBundle\ namespace. There is no functional change between v3.3.0 and v4.0.0.

$ composer remove yousign/zdd-message-bundle
$ composer require youtrust/zdd-message-bundle:^4.0

Then replace every Yousign\ZddMessageBundle\ prefix with Youtrust\ZddMessageBundle\. Beyond your PHP code, three spots live in configuration and are easy to miss:

  • the bundle class in config/bundles.php
  • the serializer service in messenger.yaml, if you use ZddMessageMessengerSerializer
  • your own implementations of ZddMessageConfigInterface and CustomMessageGeneratorInterface

The console commands are renamed to youtrust:zdd-message:*, with no alias kept for the old names. They are typically invoked from CI pipelines rather than from PHP, so unlike the namespace change this one fails at run time rather than at autoload time — update your pipelines as part of the upgrade.

yousign/zdd-message-bundle is abandoned and no longer maintained. It will receive no further release of any kind, security fixes included.

Requirements

  • PHP 8.3 and above
  • Symfony 7.4 or 8

Getting started

Installation

First, install the bundle with composer:

$ composer require youtrust/zdd-message-bundle

Then, verify that the bundle has been registered in config/bundles.php:

Youtrust\ZddMessageBundle\ZddMessageBundle::class => ['all' => true],

Configuration

Create a class to configure the messages to assert and how to create them:

<?php

namespace App\Message;

use Youtrust\ZddMessageBundle\Config\CustomMessageGeneratorInterface;
use Youtrust\ZddMessageBundle\Config\ZddMessageConfigInterface;

class MessageConfig implements ZddMessageConfigInterface, CustomMessageGeneratorInterface
{
    /**
     * Return the list of messages to assert.
     */
    #[\Override]
    public function getMessageToAssert(): array
    {
        return [
            App\Message\MyMessage::class,
            App\Message\AnotherMessage::class,
            //...
        ];
    }

    /**
     * If your message contains no scalar value as parameter such like value enums, value object more complex object,
     * you should use this method to return value for each type hint.
     */
    #[\Override]
    public function generateValueForCustomPropertyType(string $type): mixed
    {
        return match ($type) {
            'App\ValueObject\Email' => new App\ValueObject\Email('dummy@email.fr'),
            'App\Enum\MyEnum' => App\Enum\MyEnum::MY_VALUE,
            default => null,
        };
    }

    /**
     * Optional: Implement CustomMessageGeneratorInterface if you need full control
     * over how a specific message instance is created.
     * This is useful when the default instantiation (using reflection and property injection)
     * is not sufficient or when your message requires specific constructor logic.
     *
     * WARNING: The object must be instantiated with minimum requirements (i.e., nullable properties
     * must be set as null) in order to ensure a good ZDD test.
     */
    #[\Override]
    public function generateCustomMessage(string $className): ?object
    {
        return match ($className) {
            App\Message\ComplexMessage::class => new App\Message\ComplexMessage('custom data'),
            default => null,
        };
    }
}

Then, register this class as a service.

# config/services.yaml
  App\Message\MessageConfig:

Finish by updating the configuration with this new service in config/packages/zdd_message.yaml:

# config/packages/zdd_message.yaml
  zdd_message:
    message_config_service: App\Message\MessageConfig

Optional configuration

Use a custom serializer

Option to use different serializer. Possible options:

  • Youtrust\ZddMessageBundle\Serializer\ZddMessageMessengerSerializer (default, already configured for messenger serialization in messenger.yaml)
  • Define your own serializer
    • Create a service that implement Youtrust\ZddMessageBundle\Serializer\SerializerInterface
    • Use it in the configuration
# config/packages/zdd_message.yaml
  zdd_message:
    serializer: '<your-service-id>'

Custom directory for serialized messages

Option to specify a custom directory where serialized messages will be stored.

# config/packages/zdd_message.yaml
zdd_message:
  # ...
  serialized_messages_dir: '%kernel.project_dir%/custom/path' # Default: '%kernel.project_dir%/var/zdd-message'

Detect messages not tracked

Option to write a log message if an asynchronous message has been sent (using symfony messenger) and is not present in your configuration.

# config/packages/zdd_message.yaml
zdd_message:
  # ...
  log_untracked_messages:
    messenger:
      enable: true # false by default
      level: 'error' # warning by default

Usage

The bundle comes with commands to assert that your messages are compliant with the Zero Downtime Deployment:

$ bin/console youtrust:zdd-message:generate # Generate serialized messages in files.
$ bin/console youtrust:zdd-message:validate # Assert that the messages are compliant by deserializing them from files and call the properties.
$ bin/console youtrust:zdd-message:debug # Output all tracked messages.

💡 You should run bin/console youtrust:zdd-message:generate with the production version code and bin/console youtrust:zdd-message:validate with the version code you want to merge.

Example from the version you want to merge:

$ git checkout [production_version]
$ bin/console youtrust:zdd-message:generate
$ git checkout - # Go back to the version you want to merge
$ bin/console youtrust:zdd-message:validate

💡 Use verbose mode to see error details

$ bin/console youtrust:zdd-message:validate -vv
