Starting in November 2018, Symfony has changed the way .env files are working: https://symfony.com/doc/current/configuration.html#the-env-file-environment-variables

These changes are not realized in Codeception.

To assert this, I created a controller which just outputs an environment variable:

return new Response(getenv('MAILER_URL'));`

When I access the url with codeception (codecept_debug($I->grabPageSource());), I always get what I have in .env (should be .env.local or .env.test).

However, when I open the page in the browser in DEV environment, I get the content of .env.dev, when in TEST environment, .env.test; this is the expected behavior.

• Codeception version: 2.5.x-dev fc6deb8
• Symfony version: 4.2.1
