test and dev environment variables with docker-compose

[grambas]

we can use docker compose environment element to define symfony envs. For example DATABASE_URL.

services:
  php:
    environment:
      DATABASE_URL:  "mysql..."

Using this method all .env files, even .env.test.local file will be overwritten. In that case my tests runs on DATABASE_URL which is defined in docker-compose what is wrong, becouse test env has another database connection. My question is if it is possible to define symfony envs with docker-compsose for both dev and test environment

Your DATABASE_URL for your tests can be defined in the phpunit.xml file.

Otherwise you have to define your APP_ENV=test in the phpunit.xml and use a bootstrap file to load your configuration with something like this : (new Dotenv())->bootEnv(dirname(__DIR__)'/.env');.

As mentioned in #379, we need to rework this.
