测试 Eloquent Model

老师用的phpstrom主题是那个主题 感觉很干净

站长，调用create()方法时，报Error: Call to a member function make() on null ?

jelly老师，我运行test的时候出现以下问题

There was 1 error:

1) Tests\Unit\ArticleTest::itFetchesTrendingArticles
InvalidArgumentException: Unable to locate factory with name [default] [App\Article].

奇怪的是，我在tinker里面运行factory方法却一点问题都没有，我试过清除缓存和composer dump-autoload也没有效果，请问老师问题是出现在哪里呢？@jellybool
我的factory方法

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

我的testcase

class ArticleTest extends TestCase {
    /** @test */
    public function itFetchesTrendingArticles(){
        factory(Article::class,3)->create();
        factory(Article::class)->create(['read' => 10]);
        $mostPopular = factory(Article::class)->create(['read' => 20]);

        $articles = Article::trending();

        $this->assertEquals($mostPopular->id, $articles->first()->id);
    }
}

我的article model

use Illuminate\Database\Eloquent\Model;

class Article extends Model
{
    public function scopeTrending($query){

    }
}

$mostPopular = factory(Article::class, 1)->create([‘reads’ => 20]);
laravel5.5 返回的是 all collection格式
断言时
$this->assertEquals($mostPopular->first()->id, $articles->first()->id);
