Testing Symfony custom maker (maker bundle) - php

Question

I'm trying to make a custom maker with the Symfony make bundle.
The maker command looks like this:
<?php
namespace App\Maker;
use Doctrine\Common\Annotations\Annotation;
use Symfony\Bundle\MakerBundle\ConsoleStyle;
use Symfony\Bundle\MakerBundle\DependencyBuilder;
use Symfony\Bundle\MakerBundle\Generator;
use Symfony\Bundle\MakerBundle\InputConfiguration;
use Symfony\Bundle\MakerBundle\Maker\AbstractMaker;
use Symfony\Bundle\MakerBundle\Str;
use Symfony\Component\Console\Command\Command;
use Symfony\Component\Console\Input\InputArgument;
use Symfony\Component\Console\Input\InputInterface;
final class MakeCustomEntity extends AbstractMaker
{
public static function getCommandName(): string
{
return 'make:custom-entity';
}
public static function getCommandDescription(): string
{
return 'Creates a new entity';
}
public function configureCommand(Command $command, InputConfiguration $inputConf)
{
$command
->addArgument('entity-class', InputArgument::OPTIONAL, sprintf('Choose a name for your entity class (e.g. <fg=yellow>%s</>)', Str::asClassName(Str::getRandomTerm())));
}
public function generate(InputInterface $input, ConsoleStyle $io, Generator $generator)
{
}
public function configureDependencies(DependencyBuilder $dependencies)
{
$dependencies->addClassDependency(
Annotation::class,
'doctrine/annotations'
);
}
}
So far so good, the custom maker shows up when listing all commands.
However I would like to write a test for this maker (inspired from the tests I have found on the bundles github):
<?php
namespace Tests\Maker;
use App\Maker\MakeCustomEntity;
use Symfony\Bundle\MakerBundle\Test\MakerTestCase;
use Symfony\Bundle\MakerBundle\Test\MakerTestDetails;
class MakeCustomEntityTest extends MakerTestCase
{
public function getTestDetails()
{
yield 'entity_full_custom_namespace' => [
MakerTestDetails::createTest(
$this->getMakerInstance(MakeCustomEntity::class),
[
// entity class name
'\App\Domain\Entity\Test\Test',
]
)
->assert(function (string $output, string $directory) {
$this->assertStringContainsString('created: src/Domain/Entity/Test/Test.php', $output);
}),
];
}
}
When I try to run this test I get the following warning and test doesn't fail even though it should:
The data provider specified for Tests\Maker\MakeCustomEntityTest::testExecute is invalid.
You have requested a non-existent service "maker.maker.make_custom_entity". Did you mean one of these: "maker.maker.make_authenticator",...
Is this the correct way to testing custom makers? What should I do to avoid this?
