使用Queue :: fake()测试监听器 [英] Testing listeners with Queue::fake()

问题描述

我的Laravel 5.5应用程序具有 Product 模型. Product 模型具有一个 dispatchesEvents 属性，如下所示:

My Laravel 5.5 application has a Product model. The Product model has a dispatchesEvents property that looks like this:

/**
 * The event map for the model.
 *
 * @var array
 */
protected $dispatchesEvents = [
    'created' => ProductCreated::class,
    'updated' => ProductUpdated::class,
    'deleted' => ProductDeleted::class
];

我还有一个名为 CreateProductInMagento 的侦听器，该侦听器映射到 EventServiceProvider 中的 ProductCreated 事件.该侦听器实现 ShouldQueue 接口.

I also have a listener that is called CreateProductInMagento which is mapped to the ProductCreated event in the EventServiceProvider. This listener implements the ShouldQueue interface.

创建产品时，将触发 ProductCreated 事件，并将 CreateProductInMagento 侦听器推入队列并运行.

When a product is created, the ProductCreated event is fired and the CreateProductInMagento listener is pushed to the queue and is run.

我现在正尝试为所有这些编写测试.这是我所拥有的:

I am now trying to write a test for all of this. Here is what I have:

/** @test */
public function a_created_product_is_pushed_to_the_queue_so_it_can_be_added_to_magento()
{
    Queue::fake();

    factory(Product::class)->create();

    Queue::assertPushed(CreateProductInMagento::class);
}

但是我得到一个预期的[App \ Listeners \ Magento \ Product \ CreateProductInMagento]作业未推送.错误消息.

But I get a The expected [App\Listeners\Magento\Product\CreateProductInMagento] job was not pushed. error message.

如何使用Laravel的 Queue :: fake()方法测试可排队的侦听器?

How do I test queueable listeners using Laravel's Queue::fake() method?

推荐答案

此处的问题是，侦听器不是推送到队列的作业.取而代之的是，有一个 Illuminate \ Events \ CallQueuedListener 作业排队，并且在解析后将依次调用适当的侦听器.

The problem here is that the listener is not the job pushed to the queue. Instead, there's a Illuminate\Events\CallQueuedListener job that is queued and will in turn call the appropriate listener when resolved.

所以您可以这样声明:

Queue::assertPushed(CallQueuedListener::class, function ($job) {
    return $job->class == CreateProductInMagento::class;
});
