Class-Based Factories with Laravel Poser

 With Laravel Poser, you can “create class-based model factories in Laravel applications in seconds.” This package works by creating factory classes by hand or using the artisan make:poser command:

1namespace Tests\Factories;
2 
3use Lukeraymonddowning\Poser\Factory;
4 
5class UserFactory extends Factory {}

Here’s a basic example of a test case using a Poser factory class:

1/** @test */
2public function a_user_can_have_customers()
3{
4    UserFactory::times(20)
5               ->hasAddress()
6               ->withCustomers(CustomerFactory::times(20)->withBooks(5))();
7 
8    $this->assertCount(20 * 20 * 5, Book::all());
9}

Poser is smart enough to figure out that withCustomers() is a reference to a CustomerFactory class, so you could write it as follows instead:

1/** @test */
2public function user_has_customers()
3{
4    $user = UserFactory::new()
5        ->withCustomers(30)
6        ->create();
7 
8    $this->assertCount(30, $user->customers);
9}

Another highlight is the ability to encapsulate everyday factory tasks:

 1class CompanyFactory extends Factory
 2{
 3    public function withMainUser()
 4    {
 5        return $this->afterCreating(function(Company $company) {
 6            $company->setMainUser(
 7                UserFactory::new()
 8                    ->forCompany($company)->create()
 9            );
10        });
11    }
12}
