Alice - Expressive fixtures generator

Relying on fzaninotto/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 being updated for alice 3.0. If you want to check the documentation for 2.x, head here.

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:^3.0@beta

Example

Here is a complete example of entity declaration:

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