php - 在 Laravel-Doctrine 中使用工厂时调用未定义的方法 newCollection

Question

我想使用 Model factories ，但我收到此错误:

1) Tests\Factory\UserFactoryTest::testUserCount
Error: Call to undefined method App\Entities\User::newCollection()

C:\Projects\factory_test\vendor\laravel\framework\src\Illuminate\Database\Eloquent\FactoryBuilder.php:228
C:\Projects\factory_test\vendor\laravel\framework\src\Illuminate\Database\Eloquent\FactoryBuilder.php:178
C:\Projects\factory_test\tests\Factory\UserFactoryTest.php:21

工厂代码复制自 Laravel-Doctrine example project :

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

我做错了什么？在使用工厂之前，我是否需要额外的配置？ Doctrine 完美无缺，我只有 factory()

有问题

测试类如下所示:

class UserFactoryTest extends TestCase {

    private $users = array();

    protected function setUp(): void
    {
        parent::setUp();

        $this->users = factory(User::class, 3)->create();
    }

    // ...

}

Answer 1

您的 setUp() 函数使用标准的 Laravel factory() 助手来生成测试数据。

将此更改为:

protected function setUp(): void
{
    parent::setUp();
    $this->users = entity(User::class, 3)->create();
    //             ^^^^^^
}

Laravel 原则 entity() helper method在幕后使用与标准 Laravel factory() 辅助方法不同的基类。

// Laravel Doctrine
$factory = app('LaravelDoctrine\ORM\Testing\Factory');

与 factory() helper method 比较在 Laravel 框架中:

// Laravel framework
$factory = app(EloquentFactory::class);
