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。

在我的测试中，我使用$this->expectsEvents它来测试事件是否被触发。测试类看起来有点像这样：

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 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');
    }
}

我看到调用 parent::__construct 的唯一地方是 in Illuminate\Broadcasting\PrivateChannel，它扩展了 Illuminate\Broadcasting\Channel （它是一个子类，所以我不明白为什么它会抛出这个错误）：

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);
    }
}

stacktrace 看起来像这样，让我相信 Mockery 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 - 结果mockery/mockery是0.9在我的composer.json. 升级mockery/mockery到版本1.3为我解决了这个问题。

相关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

setUp可能的罪魁祸首是由于对and的新语法要求tearDown。 来源

这可能是由于缺少返回类型（即void.

例如，改变这个：

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

public function tearDown()
{
    parent::tearDown();

}

对此：

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

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

}

注意：我发现这个问题是在单元测试中寻找错误消息，奇怪的是它与 相关m::close()，所以我描述的问题与原始问题不同，但我的回答将是相关的。
