所以我定义了事件和侦听器类,并将它们注册在EventServiceProvider.php的$ listen数组中。这是代码:
use App\Events\EpisodeCreated;
use App\Listeners\NewEpisodeListener;
use Event;
class EventServiceProvider extends ServiceProvider {
protected $listen = [
EpisodeCreated::class => [
NewEpisodeListener::class
]
];
}
,然后在EventServiceProvider的启动方法中,我有以下内容:
public function boot() {
Episode::created(function($episode) {
Event::fire(new EpisodeCreated($episode));
});
}
这是EpisodeCreated事件类:
namespace App\Events;
use App\Models\Episode;
class EpisodeCreated extends Event {
public $episode;
public function __construct(Episode $episode) {
$this->episode = $episode;
}
}
最后是听众:
namespace App\Listeners;
use App\Events\EpisodeCreated;
use App\Facades\EventHandler;
use App\Http\Resources\ShowResource;
class NewEpisodeListener {
public function __construct() {
}
public function handle(EpisodeCreated $event) {
EventHandler::sendNewEpisode((new ShowResource($event->episode->show))->toArray());
}
}
最后,我编写了以下单元测试,以确保事件正在触发。似乎不是:
public function testNewEpisodeEventFiredOff() {
Event::fake();
$show = factory(Show::class)->create();
$episode = factory(Episode::class)->create(['show_id' => $show->id]);
Event::assertDispatched(EpisodeCreated::class);
}
我收到一条错误消息,说我运行phpunit时从未调度该事件。我还添加了echo调试语句,并且在创建EpisodeCreated对象时,未触发NewEpisodeListener。大家能提供的任何帮助将不胜感激。

好吧,我的问题似乎是我在EventServiceProvider
中定义了启动方法而没有调用parent::boot()
。由于我将代码重构为完全不使用boot方法,因此我将其删除,现在看来效果更好。

我遇到了问题,可以解决此问题。您应该将以下代码添加到EventServiceProvider类:
public function register()
{
$this->boot();
}
当boot method
由UnitTest或我不知道为什么的命令行命令运行时,似乎没有被调用。
