Package versionBuild StatusSlackLicense

Relying onFakerPHP/Faker, Aliceallows you to create a ton of fixtures/fake data for use while developingor testing your project. It gives you a few essential tools to make itvery easy to generate complex data with constraints in a readable and easyto 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 documentationfor 2.x, followthis 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 viaComposer asnelmio/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:Adminsowner:'@user1'members:'<numberBetween(1, 10)>x @user*'created:'<dateTimeBetween("-200 days", "now")>'updated:'<dateTimeBetween($created, "now")>'

You can then load them easily with:

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

Or load an array right away:

$loader =newNelmio\Alice\Loader\NativeLoader();$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 thecontribution guide.

Backward Compatibility Promise (BCP)

The policy is for the major part following the same asSymfony's one with a few changes orhighlights:

  • 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 servicemay 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

Check theupgrade guide.
