EventSauce Message Storage Monorepo

This repository contains multiple packages that all implement a part of EventSauce's storage related interfaces.

Message Repositories

Message repositories are used to store messages in for aggregate root reconstitution.

Docs coming soon...

Message Outboxes

A message outbox can be used to dispatching of messages via a database buffer table. Doing so allows you to ensure message persistence and dispatching happens in a single transaction.

Testing

Dependencies

Testing these packages requires accessing a MySQL 8 database.

By default, the tests assume MySQL is running on 127.0.0.1 and listening on port 3306.

To run tests with a different host or port, the following environment variables can be set:

• EVENTSAUCE_TESTING_MYSQL_HOST: Set to the IP address of the host running MySQL.
• EVENTSAUCE_TESTING_MYSQL_PORT: Set to the port that MySQL is listening on.

Running

Schema

All tests require the expected schema to be in place. This schema can be created by running:

php src/wait-for-and-setup-database.php

Test all implementations except Doctrine 2

The test suite includes tests for multiple implementations.

The test suite includes tests for two major versions of Doctrine (2 and 3) that are not compatible with each other and cannot be installed at the same time.

This means we can test all implementations together except for the Doctrine 2 implementation.

Running all tests except for the Doctrine 2 tests can be accomplished by excluding tests in the doctrine2 group.

./vendor/bin/phpunit --verbose --exclude-group=doctrine2

Doctrine 2 tests

In order to test the Doctrine 2 implementation, the dependencies for the project must first be updated to use Doctrine 2 instead of the Doctrine 3 default.

composer require doctrine/dbal:^2.6

This will replace Doctrine 3 with Doctrine 2. This means the Doctrine 3 tests will no longer run correctly.

After the Composer dependencies are downgraded to Doctrine 2 the Doctrine 2 implementation can be tested. Since the rest of the implementations are already tested using the first method, testing the Doctrine 2 implementation can be accomplished by only running tests in the doctrine2 group.

./vendor/bin/phpunit --verbose --group=doctrine2

Take care to not include the changes to composer.json in any PR you intend to share.

Docker Compose

This package ships with a Docker Compose file in the project's root directory. This can be used to create a MySQL 8 server that can be used for testing this package.

Run:

docker-compose up

Once running, the testing commands can be run.
