This package adds support the laravel's Model Factory' functionnality to the Analogue datamapper ORM.

Installation

Add this line to your composer.json file :

composer require analogue/factory

Configuration

Add the Service Provider to config/app.php :

'Analogue\Factory\FactoryServiceProvider',

Usage

Analogue Factory uses the same definitions mechanism Eloquent's does. Out of the box, this file provided with the default Laravel's install contains one factory definition:

$factory->define(App\User::class, function (Faker\Generator $faker) {
    return [
        'name' => $faker->name,
        'email' => $faker->email,
        'password' => bcrypt(str_random(10)),
        'remember_token' => str_random(10),
    ];
});

Within the Closure, which serves as the factory definition, you may return the default test values of all attributes on the model. The Closure will receive an instance of the Faker PHP library, which allows you to conveniently generate various kinds of random data for testing.

Of course, you are free to add your own additional factories to the ModelFactory.php file.

Multiple Factory Types

Sometimes you may wish to have multiple factories for the same Analogue Entity class. For example, perhaps you would like to have a factory for "Administrator" users in addition to normal users. You may define these factories using the defineAs method:

$factory->defineAs(App\User::class, 'admin', function ($faker) {
    return [
        'name' => $faker->name,
        'email' => $faker->email,
        'password' => str_random(10),
        'remember_token' => str_random(10),
        'admin' => true,
    ];
});

Instead of duplicating all of the attributes from your base user factory, you may use the raw method to retrieve the base attributes. Once you have the attributes, simply supplement them with any additional values you require:

$factory->defineAs(App\User::class, 'admin', function ($faker) use ($factory) {
    $user = $factory->raw(App\User::class);

    return array_merge($user, ['admin' => true]);
});

Using Factories In Tests

Once you have defined your factories, you may use them in your tests or database seed files to generate model instances using the global analogue_factory function. So, let's take a look at a few examples of creating models. First, we'll use the make method, which creates models but does not save them to the database:

public function testDatabase()
{
    $user = analogue_factory(App\User::class)->make();

    // Use entity in tests...
}

If you would like to override some of the default values of your entities, you may pass an array of values to the make method. Only the specified values will be replaced while the rest of the values remain set to their default values as specified by the factory:

$user = analogue_factory(App\User::class)->make([
    'name' => 'Abigail',
   ]);

You may also create a Collection of many models or create models of a given type:

// Create three App\User instances...
$users = analogue_factory(App\User::class, 3)->make();

// Create an App\User "admin" instance...
$user = analogue_factory(App\User::class, 'admin')->make();

// Create three App\User "admin" instances...
$users = analogue_factory(App\User::class, 'admin', 3)->make();

Persisting Factory Entities

The create method not only creates the model instances, but also saves them to the database using Analogue's Mapper store() method.

public function testDatabase()
{
    $user = analogue_factory(App\User::class)->create();

    // Use entity in tests...
}

Again, you may override attributes on the model by passing an array to the create method:

$user = analogue_factory(App\User::class)->create([
    'name' => 'Abigail',
   ]);

Building complex Entities

By recursively calling the analogue_factory function, you can generate complex Entities very easily :

$factory->define(App\Post::class, function (Faker\Generator $faker) {
    return [
        'title' => $faker->sentence,
        'content' => $faker->text,
    ];
});

$factory->define(App\User::class, function (Faker\Generator $faker) {
    return [
        'name' => $faker->name,
        'posts' => analogue_factory(App\Post::class, 10),
    ];
});

You can even persist these complex entities with a single call :

$users = analogue_factory(App\User::class, 3)->create();
