Dedicated test databases with Laravel Sail

#laravel #php #sail

I’ve been playing around with Laravel Sail on a project that I’ve just started and wanted to be able to run my tests on a separate database and leave my main DB intact for development.

Adding a second database for tests involves adding a second container and configuring your tests to point at the newly created host.

Add the following to docker-compose.yml under the services: key:

mysql_test: image: "mysql:8.0" environment: MYSQL_ROOT_PASSWORD: "${DB_PASSWORD}" MYSQL_DATABASE: "${DB_DATABASE}" MYSQL_USER: "${DB_USERNAME}" MYSQL_PASSWORD: "${DB_PASSWORD}" MYSQL_ALLOW_EMPTY_PASSWORD: "yes" networks: - sail
Enter fullscreen mode Exit fullscreen mode

Next, configure your .env.testing file to point at the mysql_test host (Docker Compose uses the service name as the host name for networking):

# Don't forget to set APP_KEY too DB_HOST=mysql_test # This is the important bit DB_DATABASE= DB_USERNAME=root
Enter fullscreen mode Exit fullscreen mode

Then finally, run your tests:

./vendor/bin/sail test
Enter fullscreen mode Exit fullscreen mode
