工厂定义：

public function definition()
{
    return [
        'user_id' => function() {
            return User::factory()->create()->id;
        },
        'category_id' => function() {
            return Category::factory()->create()->id;
        },
        'title' => $this->faker->sentence,
        'body' => $this->faker->paragraph,
    ];
}

抛出错误的测试

<?php

namespace Tests\Unit;

use App\Models\Question;
use PHPUnit\Framework\TestCase;

class QuestionTest extends TestCase
{
    protected $question;

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

        $this->question = Question::factory()->create();
    }


    public function test_it_has_an_owner()
    {
        $this->assertInstanceOf('App\User', $this->question->creator);
    }
}

那是错误：

有 1 个错误：

1) Tests\Unit\QuestionTest::test_it_has_an_owner
