profiles_display_all_threads_created_by_the_associated_user 测试会报错

/** @test */
public function profiles_display_all_threads_created_by_the_associated_user()
{
    $user = create('App\Models\User');
    $this->signIn($user);

    $thread = create('App\Models\Thread', ['user_id' => $user->id]);
    $this->get("/profiles/{$user->name}")
        ->assertSee($thread->title)
        ->assertSee($thread->body);
}

我加了登录之后，这个报错才没有，不知道有没有人跟我遇到同样的问题！
