Neos Flow Alice connector

Neos Flow package for expressive fixture generation based on Alice.

The Swisscom.AliceConnector simply provides a Context that connects your functional test cases with Alice.

Getting started

Install the package through composer. You likely require it for dev only.

composer require --dev swisscom/aliceconnector

Configuration

Set the path to your fixture files in the Settings.yaml:

Swisscom:
  AliceConnector:
    fixtureSets:
      default: '%FLOW_PATH_PACKAGES%Application/Your.Package/Tests/Fixtures/{name}.yaml'

Fixture creation

Create your file based Alice fixtures under the path defined in fixtureSets.

This basic example stored as Company.yaml defines a single fixture object for the domain model Company:

Your\Package\Domain\Model\Company:
  company1:
    name: 'Swisscom'

For a more real case example and documentation reference about the notation go to "[What does Alice?](#What does Alice?)".

Usage

Use the Context in your test and load the fixtures. $testablePersistenceEnabled should be enabled to work with persistence.

<?php
namespace Your\Package\Tests\Functional;

use Swisscom\AliceConnector\Context;
use Neos\Flow\Tests\FunctionalTestCase;

class CompanyTest extends FunctionalTestCase
{

    /**
     * @var Context
     */
    protected $fixtureContext;

    public function setUp()
    {
        parent::setUp();
        $this->fixtureContext = new Context($this->objectManager, $this::$testablePersistenceEnabled);
    }
    
    /**
     * @test
     */
    public function companyTest()
    {
        $fixtures = $this->fixtureContext->loadFixture('Company');
        $company = $fixtures['company1'];
        self::assertSame('Swisscom', $company->getName());
    }
}

If you have persistence enabled, you could also query the fixture through your repository:

$companyRepository = $this->objectManager->get(CompanyRepository::class);
$company = $companyRepository->findOneByName('Swisscom');

This example loads the fixture defined in %FLOW_PATH_PACKAGES%/Application/Your.Package/Tests/Fixtures/Company.yaml'

What does Alice?

Alice allows you to define expressive fixtures based on YAML, JSON or PHP files. Alice again is relying on Faker to create fake data for your fixtures.

The following sample shows you the real gain of Alice creating 10 random Person entities with account and related entities:

Neos\Flow\Security\Account:
  account{1..10}:
    accountIdentifier: 'user<current()>'
    credentialsSource: <passwordHash('12345678')>
    authenticationProviderName: UsernamePasswordTestingProvider
    roles:
      - <role('Your.Package:User')>

Neos\Party\Domain\Model\PersonName:
  personName{1..10}:
    firstName: '<firstName()>'
    lastName: '<lastName()>'

Neos\Party\Domain\Model\ElectronicAddress:
  electronicAddress{1..10}:
    identifier (unique): '<email()>'
    type: Email

Neos\Party\Domain\Model\Person:
  person{1..10}:
    name: '@personName<current()>'
    primaryElectronicAddress: '@electronicAddress<current()>'
    accounts:
    - '@account<current()>'

We use fixture ranges {1..10} to create the 10 objects each, fixture references (e.g. @personName) as well as faked data through faker formatters (e.g. firstName()).

See the complete Alice reference for detailed information and more features.

What does Faker?

Faker simply provides random dummy data for your fixtures by providing formatters which can be used in Alice. See the available Faker formatters for complete reference.

The faker formatters are directly called in the fixture definition file.

Additionally, the Context exposes the faker generator through getFaker(), so that formatters can be used even directly in your code.

Custom Flow formatters

The package provides the following custom formatters for your Flow application.

Collection

A doctrine array collection:

$collection = $faker->arrayCollection([$item1, $item2]);

Resource

A persistent resource:

$resource = $faker->persistentResource('Dummy.txt');

Image asset with reference to a persistent resource:

$image = $faker->persistentResourceImage('Dummy.png');

Document asset with reference to a persistent resource:

$document = $faker->persistentResourceDocument('Dummy.pdf');

Security

Password hash for the given password:

$image = $faker->hashPassword('12345678');

Role object for the identifier:

$image = $faker->role('Your.Package:User');

Notes

  • Context and providers are all stored inside the Classes folder to make them available not only for test cases. Possible use cases are fixture generation on demo environments or even master data imports on prod environments.
