Data Fixture For PHPUnit Bundle

This is a Symfony Bundle to use Symfony DoctrineFixturesBundle in PHPUnit test directly.

Requirements

• Symfony DoctrineFixturesBundle
• PHPUnit
• (optional, but recommended) Faker

Install

1. Create a config file (see Minimal Configuration)
2. run composer require --dev dknx01/data-fixtures-phpunit

Usage

If you want to use data fixtures in you tests you can do it in multiple ways. You can write a method to fill data in the database. or you can use a fixture and reuse it in multiple tests.

Configuration

Ensure you have the following file:

# config/packages/data_fixtures_php_unit.yaml
data_fixtures_php_unit:
  faker:
    locale: 'de_DE' # optional - defaults to en_EN
    providers:
      - 'App\Tests\Faker\Bundeslaender' # optional - defaults to empty array

locale and providers are optional and only needed if you want to change the default behavior.

Minimal Configuration

The minimal setup would look like:

# config/packages/data_fixtures_php_unit.yaml
data_fixtures_php_unit:
  faker:

Fixtures registration

You should have all your Fixture classes registered as a services - at leat inside the test container.

All Fixtures that are in the namespace App\Tests\Fixtures\ and inside the folder '%kernel.project_dir%/tests/Fixtures' are automatically registered.

Example registration:

when@test:
  services:
    _defaults:
      autowire: true
      autoconfigure: true
      public: true
    App\Tests\Fixtures\:
      resource: '%kernel.project_dir%/tests/Fixtures'

Writing a fixture

Each fixture must implement the Doctrine\Common\DataFixtures\FixtureInterface;. Example:

<?php

namespace App\Tests\Fixtures;

use App\Entity\User;
use Dknx01\DataFixturesPhpUnit\Contract\FakerAware;
use Doctrine\Common\DataFixtures\FixtureInterface;
use Doctrine\Persistence\ObjectManager;
use Faker\Generator;

readonly class UserFixture implements FixtureInterface, FakerAware
{
    private Generator $faker;

    public function __construct(private string $email = '')
    {
    }

    public function setFaker(Generator $faker): void
    {
        $this->faker = $faker;
    }

    public function load(ObjectManager $manager): void
    {
        $user = new User();
        $user->setEmail(!empty($this->email) ? $this->email : $this->faker->unique()->safeEmail());
        $user->setPassword('foo');
        $user->setRoles(['ROLE_USER']);
        $manager->persist($user);
        $manager->flush();
    }
}

#[DataFixture(new UserFixture('test@fooo.nlkdjlfs'))]
class ApiTest extends ApplicationTestCase {
 // your code
}

#[DataFixture(UserFixture::class)]
class ApiTest extends ApplicationTestCase {
    // your code
}

As you can see the fixture can have constructor arguments for individual data in different tests.

Data Fixture on method level

Data fixtures can be used on class level (see above) and on method level.

#[DataFixture(UserFixture::class)]
#[DataFixture(new BlaFixture(
    name: 'Test123',
    fileName: 'Test123'
))]
public function testFoo(): void
{
    // cor code
}

Dependent Fixtures

Fixtures can depend on other fixtures. You can use the way Doctrine data fixtures is suggesting, or you can use an attribute.

#[DependFixture(BarFixture::class)]
class FooFixture implements FixtureInterface, FakerAware
{
    // your code
}

Faker

As you can see it is possible to use PHPFaker inside a fixture class.

If you implement the FakerAware interface a Faker instance is automatically injected into the data fixture.

Limitations

• A fixture class can only be used once for a test, regardless of whether the DataFixture is defined on a class basis or a method basis
  • This is invalid and will only execute on fixture, mostly the latest defined one

    #[DataFixture(new BarFixture('first'))]
    #[DataFixture(BarFixture::class)]
    public function testFoo(): void
    {
    // code
    }
