Hyperf Fakie

This PHP Hyperf library aim to help you generate objects fully populated with fake/random data for testing purposes.

Installation

composer require jainec/hyperf-fakie

Configuration

Publish the config file so you can define your own rules

php bin/hyperf.php vendor:publish jainec/hyperf-fakie

The config file will show up in the following path:

config/autoload/fakie.php

Here in the file you can define your own creation rules for specific classes and properties

<?php

declare(strict_types=1);

return [
    'rules' => [
        'App\Entity\User' => [
            'type' => array_rand(['CONSUMER', 'SELLER']),
        ],
        'App\Entity\Order' => [
            'type' => array_rand(['VIRTUAL', 'PHYSICAL']),
        ],
        'Class' => [
            'property1' => 'rule1',
            'property2' => 'rule2',
        ],
    ],
];

Usage

Simple usage

Without hyperf-fakie

// Ex.: Generating an OrderHistory object for testing purposes
$order = new Order(
    id: rand(),
    type: array_rand(['VIRTUAL', 'PHYSICAL']),
    amount: rand(),
    value: rand() / 100,
);

$user = new User(
    name: Str::random(),
    telephone: Str::random(),
    city: Str::random(),
);

$order_history = new OrderHistory(
    id: rand(),
    description: Str::random(),
    order: $order,
    user: $user,
);

See how it's simple with hyperf-Fakie

// Ex.: Generating an OrderHistory object for testing purposes with fakie
$order_history = Fakie::object(OrderHistory::class)->create();

Overriding properties values

$user = Fakie::object(OrderHistory::class)->create([
    'description' => 'Specific description for specific test case'
]);

Using a method to build the object other than the __construct()

You can use this feature only if your object can be built using a method that accepts an array with the [properties => values] as argument

$user = Fakie::object(UserDTO::class, 'fromArray')->create();

In this case Fakie will create and assign random values to all properties of the class. If there are properties your method don't need to receive, you can remove them using the excludeProperties

$user = Fakie::object(UserDTO::class, 'fromArray')->excludeProperties(['type', 'age'])->create();

In the example above the properties type and age will not be used and will not be passed to fromArray method

Important

Fakie uses the classes properties types to generate and assign random values to them
If a property doesn't have a defined type, a default string value will be assigned to it
If a property type is array or array<Type> it's recommended to you define your own rules in the config fakie.php file. Because we know with PHP we cannot be sure about what is expected inside an array
If a property type is abstract/interface, you need to define your own rules for these cases specifying a concrete class
You can also use Fakie objects to specify rules in you config file:

<?php

declare(strict_types=1);

return [
    'rules' => [
        'App\Entity\OrderHistory' => [
            'order' => Fakie::object(Order::class), // Don't call the create() method here
            'user' => Fakie::object(User::class, 'fromArray'), // Don't call the create() method here
        ],
    ],
];
