phpunit，laravel：当前类范围中没有父级时，不能使用“父级”

Question

我在PHP 7.4上使用PHPUnit 6.5.13和Laravel 5.5。我最近从PHP 7.2升级到7.4。似乎触发了错误。

在测试中，我使用$this->expectsEvents来测试是否触发了事件。测试类看起来像这样：

namespace Tests\Feature;
use Tests\TestCase;
use App\Events\OrderReSent;

class MyEventTest extends TestCase {
    /** @test */
    public function authenticated_client_can_resend()
    {
        $this->expectsEvents(OrderReSent::class); // there is some more code but this is the line that returns the error
    }
}

OrderReSent看起来像这样（我尝试注释掉broadcastOn并删除InteractsWithSockets的使用，结果没有变化）：

namespace App\Events;

use Illuminate\Broadcasting\Channel;
use Illuminate\Queue\SerializesModels;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Broadcasting\PresenceChannel;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;

class OrderReSent
{
    use Dispatchable, InteractsWithSockets, SerializesModels;

    public $invoiceId;

    public function __construct($invoiceId)
    {
        $this->invoiceId = $invoiceId;
    }

    public function broadcastOn()
    {
        return new PrivateChannel('channel-name');
    }
}

我看到被调用parent :: __ construct的唯一地方是在Illuminate\Broadcasting\PrivateChannel中，它扩展了Illuminate \ Broadcasting \ Channel（这是一个子类，所以我不明白为什么会引发此错误）：

namespace Illuminate\Broadcasting;

class PrivateChannel extends Channel
{
    /**
     * Create a new channel instance.
     *
     * @param  string  $name
     * @return void
     */
    public function __construct($name)
    {
        parent::__construct('private-'.$name);
    }
}

堆栈跟踪看起来像这样，使我相信嘲笑是罪魁祸首：

1) Tests\Feature\MyEventTest::authenticated_client_can_resend
ErrorException: Cannot use "parent" when current class scope has no parent

我有同样的问题-事实证明，我的mockery/mockery中将0.9设置为版本composer.json。 mockery/mockery升级到1.3版本为我解决了这个问题。

相关的composer.json片段：

        "mockery/mockery": "~1.3.0",
        "phpunit/phpunit": "~8.0",

尝试设置相同的版本并运行composer update
