Symfony 5.4 .env.test does not overwrite .env when using phpunit

Question

I have upgraded Symfony from 4.4 to 5.4. Every dependencies have been upgraded and recipes installed.

I have a .env and a .env.test (nothing else in terms of dotenv).

I also have a phpunit.xml.dist as described in the Symfony recipe (the exact same file, with the ). My tests/bootstrap.php is also the same.

When doing functional tests, the environment variables are loaded from the .env but the .env.test isn't loaded. I know that because the tests does not find variables set in the .env.test. I also find out that the APP_ENV has not changed and still "dev", and I really don't know why. I thought that the APP_ENV in phpunit.xml.dist was the key to load the test environment, but it's not.

The command I use to run the tests

php bin/phpunit

Does someone already have this kind of problem with a Symfony upgrade ? I really tested everything I know to solve this issue.

As my files are all the same than the recipe, I just provide my composer.json. Maybe the problem comes from here, and an example of a test I do.

Feel free to ask anything else.

The test example :

class AccueilControllerTest extends WebTestCase
{
    private KernelBrowser $client;

    protected function setUp(): void
    {
        $kernel = self::bootKernel();
        static::ensureKernelShutdown();
        $this->client = static::createClient();
    }

    /**
     * @return void
     */
    public function testUserNotLoggedIndexRedirectsLogin()
    {
        $this->client->request('GET', '/calculatrice_nos/');
        $this->assertEquals(Response::HTTP_FOUND, $this->client->getResponse()->getStatusCode());

        $expectedRedirectUrl = $this->client->getContainer()->get('router')->generate('app_login', [], UrlGeneratorInterface::ABSOLUTE_URL);
        $this->assertTrue($this->client->getResponse()->isRedirect($expectedRedirectUrl));
    }
    
    //...
}

This is my phpunit.xml.dist which does not work. As a workaround, I managed to add APP_ENV as server and env var in a new version. But that's not clean.

In phpunit.xml.dist set (at least) the APP_ENV var

<?xml version="1.0" encoding="UTF-8"?>

         convertDeprecationsToExceptions="false"
>
    <php>

</phpunit>
