Alice - Expressive fixtures generator

Package version Build Status Slack License

Relying on FakerPHP/Faker, Alice allows you to create a ton of fixtures/fake data for use while developing or testing your project. It gives you a few essential tools to make it very easy to generate complex data with constraints in a readable and easy to edit way, so that everyone on your team can tweak the fixtures if needed.

Warning: this doc is for alice 3.0. If you want to check the documentation for 2.x, follow this link.

2.x is in maintenance mode: PRs are accepted, but no active development is done on it by the maintainers any longer.

Installation

This is installable via Composer as nelmio/alice:

composer require --dev nelmio/alice

Example

Here is a complete example of entity declaration:

Nelmio\Entity\User:
    user{1..10}:
        username: '<username()>'
        fullname: '<firstName()> <lastName()>'
        birthDate: '<date_create()>'
        email: '<email()>'
        favoriteNumber: '50%? <numberBetween(1, 200)>'

Nelmio\Entity\Group:
    group1:
        name: Admins
        owner: '@user1'
        members: '<numberBetween(1, 10)>x @user*'
        created: '<dateTimeBetween("-200 days", "now")>'
        updated: '<dateTimeBetween($created, "now")>'

You can then load them easily with:

$loader = new Nelmio\Alice\Loader\NativeLoader();
$objectSet = $loader->loadFile(__DIR__.'/fixtures.yml');

Or load an array right away:

$loader = new Nelmio\Alice\Loader\NativeLoader();
$objectSet = $loader->loadData([
    \Nelmio\Entity\User::class => [
        'user{1..10}' => [
            'username' => '<username()>',
            'fullname' => '<firstName()> <lastName()>',
            'birthDate' => '<date_create()>',
            'email' => '<email()>',
            'favoriteNumber' => '50%? <numberBetween(1, 200)>',
        ],
    ],
    \Nelmio\Entity\Group::class => [
        'group1' => [
            'name' => 'Admins',
            'owner' => '@user1',
            'members' => '<numberBetween(1, 10)>x @user*',
            'created' => '<dateTimeBetween("-200 days", "now")>',
            'updated' => '<dateTimeBetween($created, "now")>',
        ],
    ],
]);

Check the contribution guide.

Backward Compatibility Promise (BCP)

The policy is for the major part following the same as Symfony's one with a few changes or highlights:

  • Code marked with @private or @internal are excluded from the BCP
  • Nelmio\Alice\Loader\NativeLoader is excluded from the BCP: as it is the no DIC solution, registring a new service may require a new method, in which case your code may break if you have already declared that method. To avoid that, please beware of the naming of your methods to avoid any conflicts.

Upgrade
