How to setup which Symfony environment is used by unit tests? - symfony

Question

I am trying to setup a new Symfony environment named travis to run unit tests in a Travis container.
I setup this environment to distinguish it from prod and from dev.
Currently, I have:
a SYMFONY_ENV=travis environment variable setup in Travis
a config_travis.yml that contains my configuration for the Travis environment
a app_travis.php which specify the environment to load
a .travis.yml:
>
language: php
php:
- "7.2.17"
services:
- mysql
install:
- composer install --no-interaction
- echo "USE mysql;\nUPDATE user SET password=PASSWORD('${MYSQL_PASSWORD}') WHERE user='root';\nFLUSH PRIVILEGES;\n" | mysql -u root
- ./bin/console doctrine:database:create --env=travis
- ./bin/console doctrine:migration:migrate --env=travis --no-interaction
script:
- ./vendor/bin/simple-phpunit
My project looks like this:
Some examples of tests I'm running:
UserTest.php which tests the User.php model:
<?php
namespace Tests\AppBundle\Entity;
use AppBundle\Entity\User;
use PHPUnit\Framework\TestCase;
use AppBundle\Entity\Responsibility;
class UserTest extends TestCase
{
public function testId()
{
$user = new User();
$id = $user->getId();
$this->assertEquals(-1, $id);
}
}
LoginControllerTest.php which tests the LoginController.php controller:
<?php
namespace Tests\AppBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;
use Symfony\Component\Security\Core\Authentication\Token\UsernamePasswordToken;
use Symfony\Component\BrowserKit\Cookie;
use Symfony\Component\HttpFoundation\Response;
class LoginControllerTest extends WebTestCase
{
/*
* Test the login form
* Logins with (admin, password : a)
*/
public function testLogin()
{
// Create a new client to browse the app
$client = static::createClient();
$crawler = $client->request('GET', '/login');
$this->assertEquals(200, $client->getResponse()->getStatusCode(), "Unexpected HTTP status code for GET ");
// Get the form
$form = $crawler->selectButton('Connexion')->form();
// Fill the login form input
$form['_username']->setValue('admin');
$form['_password']->setValue('a');
// Send the form
$client->submit($form);
$crawler = $client->followRedirect();
$this->assertContains(
'Bienvenue admin.' ,
$client->getResponse()->getContent()
);
return array($client,$crawler);
}
}
My problem is: all the command run into the travis environment, except the unit tests. I want to be able to run the unit tests in dev env on my computer but in travis env in the Travis container.
How can I setup my PHPUnit so that it can run in travis environment and use my config_travis.yml file?

Answer 1

The createClient() method of the WebTestCase calls the bootKernel() method from the KernelTestCase which in turn calls createKernel(). In createKernel() there is the following code which determines in which environment the kernel should be booted:
if (isset($options['environment'])) {
$env = $options['environment'];
} elseif (isset($_ENV['APP_ENV'])) {
$env = $_ENV['APP_ENV'];
} elseif (isset($_SERVER['APP_ENV'])) {
$env = $_SERVER['APP_ENV'];
} else {
$env = 'test';
}
So in your case exporting the APP_ENV variable in your config_travis.yml file and setting it to travis should solve it.

Answer 2

PHPUnit uses an environment variable called APP_ENV to determines which environment is used. I had to create this environment variable in Travis.
