Utilisation d'une autre base de données pour le test phpunit sur Laravel 6 avec docker-compose.

Every engineer would hope to divide database when running test. I'll show using another database for phpunit test on Laravel 6 with docker-compose in this article.

STEP

1. Adding test database on docker-compose
2. Adding setting for test database in config/database.php
3. Adding environment at phpunit.xml
4. Create .env.testing as new env file
5. Running migration command for test database
6. Running phpunit
