phpunit,laravel:当当前 class 作用域没有 parent 时,无法使用 "parent"

phpunit, laravel: Cannot use "parent" when current class scope has no parent

我在 PHP7.4 上使用 PHP6.5.13 单元和 Laravel 5.5。我最近从 PHP 7.2 升级到 7.4。似乎这触发了错误。

在我的测试中,我使用 $this->expectsEvents 来测试事件是否被触发。测试 class 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');
    }
}

我唯一看到 parent::__construct 被调用的地方是 Illuminate\Broadcasting\PrivateChannel,它扩展了 Illuminate\Broadcasting\Channel(它是 child class,所以我不明白为什么会抛出这个错误):

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);
    }
}

堆栈跟踪看起来像这样,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

/project-root/vendor/mockery/mockery/library/Mockery/Loader/EvalLoader.php:16
/project-root/vendor/mockery/mockery/library/Mockery/Loader/EvalLoader.php:16
/project-root/vendor/mockery/mockery/library/Mockery/Container.php:219
/project-root/vendor/mockery/mockery/library/Mockery.php:89
/project-root/vendor/laravel/framework/src/Illuminate/Foundation/Testing/Concerns/MocksApplicationServices.php:99
/project-root/vendor/laravel/framework/src/Illuminate/Foundation/Testing/Concerns/MocksApplicationServices.php:54
/project-root/tests/Feature/MyEventTest.php:29

我有同样的问题 - 结果 mockery/mockery 在我的 composer.json 中设置为版本 0.9。将 mockery/mockery 升级到版本 1.3 解决了我的问题。

相关composer.json片段:

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

尝试设置相同的版本 运行 composer update

可能的罪魁祸首是 setUptearDown 的新语法要求。 Source

可能是缺少 return 类型造成的,即 void

例如,更改为:

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查找错误消息,奇怪的是它与 m::close() 有关,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。
