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

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"
xsi:noNamespaceSchemaLocation="http://schema.phpunit.de/4.1/phpunit.xsd"
backupGlobals="false"

</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')
