Question

我正在通过Laracast教程：link。我的论坛项目在浏览器中工作。我可以看到所有线程都有相关的回复。这些回复包含带时间戳的用户信息。但是phpunit测试失败了，我无法理解为什么：

λ vendor\bin\phpunit tests\Unit\ReplyTest.php
PHPUnit 5.7.21 by Sebastian Bergmann and contributors.

F                                                                   1 / 1 (100%)

Time: 360 ms, Memory: 12.00MB

There was 1 failure:

1) Tests\Unit\ReplyTest::it_has_an_owner
Failed asserting that null is an instance of class "App\User".

C:\laragon\www\forum\tests\Unit\ReplyTest.php:19

FAILURES!
Tests: 1, Assertions: 1, Failures: 1.

这是我的 ReplyTest.php ：

<?php

namespace Tests\Unit;

use Tests\TestCase;
use Illuminate\Foundation\Testing\DatabaseMigrations;


class ReplyTest extends TestCase
{
    use DatabaseMigrations;

    /** @test **/
    public function it_has_an_owner()
    {
        $reply = factory('App\User')->create();

        $this->assertInstanceOf('App\User', $reply->owner);
    }
}

我的雄辩模型 Reply.php：

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Reply extends Model
{
    public function owner()
    {
        return $this->belongsTo(User::class, 'user_id');
    }
}

来自 ModelFactory.php的代码：

<?php

/** @var \Illuminate\Database\Eloquent\Factory $factory */
$factory->define(App\User::class, function (Faker\Generator $faker) {
    static $password;

    return [
        'name' => $faker->name,
        'email' => $faker->unique()->safeEmail,
        'password' => $password ?: $password = bcrypt('secret'),
        'remember_token' => str_random(10),
    ];
});

$factory->define(App\Thread::class, function (Faker\Generator $faker) {
    static $password;

    return [
        'user_id' => function() {
            return factory('App\User')->create()->id;
        },
        'title' => $faker->sentence,
        'body' => $faker->paragraph
    ];
});

$factory->define(App\Reply::class, function (Faker\Generator $faker) {
    static $password;

    return [
        'thread_id' => function() {
            return factory('App\Thread')->create()->id;
        },

        'user_id' => function() {
            return factory('App\User')->create()->id;
        },
        'body' => $faker->paragraph
    ];
});

show.blade.php

的代码摘录

<div class="col-md-8 col-md-offset-2">
    @foreach ($thread->replies as $reply)
     <div class="panel-heading">
        <a href="#">
            {{ $reply->owner->name }}
        </a>
        said {{ $reply->created_at->diffForHumans() }} ... 
    </div> 

    <div class="panel panel-default">
        <div class="panel-body">
            {{ $reply->body }}
        </div>
    </div>
    @endforeach
</div>

我希望我发布所有相关代码 - 如果没有，请告诉我你需要什么，我会发布它。我无法弄清楚为什么phpunit会在浏览器中一切正常时返回错误。

Answer 1

最终发现了我的错误。我使用工厂的错误类和创建用户而不是回复。更改后一切正常：

$reply = factory('App\Reply')->create();

Laravel - 声明null是类“App \ User”的实例失败
