Phpunit on Symfony 3.4 You have requested a non-existent service

Question

I am working on a Symfony 3.4 installation that was upgraded from version 2.

When I try to run a unit test with this command

./bin/phpunit tests/MyBundle/ -c tests/phpunit.xml

I get the following error:

    Symfony\Component\DependencyInjection\Exception\ServiceNotFoundException: You have requested a non-existent service "XXXX\MyBundle\Services\ListServices".

/apps/xxxx/unitTest/vendor/symfony/symfony/src/Symfony/Component/DependencyInjection/Container.php:348
/apps/xxxx/unitTest/tests/MyBundle/Services/ListServicesTest.php:19

I have made the Services public

  services:
    _defaults:
      autowire: true
      autoconfigure: true
      public: true

But that did not work. I also tried adding a Compiler pass, but that was it's own can of worms...

my phpunit.xml

<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</phpunit>

this is my test file

namespace Tests\MyBundle\Services;

use XXXX\MyBundle\Services\ListServices;
use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;

class ListServicesTest extends WebTestCase
{
    /**
     * @test
     */    
public function testGetCurrentList()
    {
        $kernel = new AppKernel('dev', false);
        $kernel->boot();
        $container = $kernel->getContainer();

        $listService = $container->get(ListServices::class);

        $this->assertNotNull($listService->getCurrentList());

    }
}

Any ideas on how to get the unit tests to work? thanks

Answer 1

You are trying to get the service by it's name (class name) and not by it's alias from the container. Service should be registered in the container:

services:
    your_service_alias:
      class: YourApp\Services\ListServices
      arguments: (if any)
        - "@some_dependency"

Then in your test you should get the service by it's alias

$container->get('your_service_alias')
