How to create your own symfony controller tests or add tests to PrestaShop

If you create your own Modern (symfony) controllers or if you plan on migrating a legacy controller, you can create tests to cover parts of HTTP layer aka symfony functional tests.

Creating a functional test

To create a functional test, we encourage you to base your test class on our own implementation of WebTestCase.

For instance:

<?php
namespace Tests\Functional\Foo;

use Tests\Integration\PrestaShopBundle\Test\WebTestCase;

class BarTest extends WebTestCase
{
    public function testSomeAction()
    {
        $url = this->router->generate('route_name');
        $this->client->request('GET', $url);
        
        $response = $this->client->getResponse();
        
        self::assertTrue($response->isSuccessful());
    }
}
