        }

任务模拟

作为模拟的替代方式，你可以使用 Bus Facade 的 fake 方法来防止任务被真正分发执行。使用 fake 的时候，断言一般出现在测试代码的后面：

/**
 * 测试订单流程
 */
 public function testOrderProcess(){ 
    Event::fake([   
         OrderCreated::class,   
         ]);    
    $order = factory(Order::class)->create();    
    Event::assertDispatched(OrderCreated::class);    
   // 其他事件照常发送...    
  $order->update([...]);
 }

事件模拟

作为 mock 的替代方法，你可以使用 Event Facade 的 fake 方法来模拟事件监听，测试的时候并不会真正触发事件监听器。然后你就可以测试断言事件运行了，甚至可以检查他们接收的数据。使用 fake 的时候，断言一般出现在测试代码的后面：

<?php
    namespace Tests\Feature;
    use App\Order;use Tests\TestCase;
    use App\Events\OrderCreated;
    use Illuminate\Support\Facades\Event;
    use Illuminate\Foundation\Testing\RefreshDatabase;
    use Illuminate\Foundation\Testing\WithoutMiddleware;
    class ExampleTest extends TestCase{   
     /**
     * 测试订单流程
     */   
     public function testOrderProcess()   
      {     
         $order = Event::fakeFor(function () { 
                    $order = factory(Order::class)->create();            
                    Event::assertDispatched(OrderCreated::class);            
                    return $order;        
             });       
           // 事件按正常方式发送，观察者将运行...       
          $order->update([...]);    
        }
      }

{note} 调用 Event::fake() 后不会执行事件监听。所以，你基于事件的测试必须使用工厂模型，例如，在模型的 creating 事件中创建 UUID ，你应该调用 Event::fake() 之后 使用工厂模型。

模拟事件的子集

如果你只想为特定的一组事件模拟事件监听器，你可以将它们传递给 fake 或 fakeFor 方法:

<?php
    namespace Tests\Feature;
    use Tests\TestCase;use App\Mail\OrderShipped;
    use Illuminate\Support\Facades\Mail;
    use Illuminate\Foundation\Testing\RefreshDatabase;
    use Illuminate\Foundation\Testing\WithoutMiddleware;
    class ExampleTest extends TestCase{ 
       public function testOrderShipping()  
         {     
            Mail::fake();        
            // 断言没有发送任何邮件...        
            Mail::assertNothingSent();        
            // 执行订单发送...        
            Mail::assertSent(OrderShipped::class, function ($mail) use ($order) {  
                      return $mail->order->id === $order->id;       
                   });        
           // 断言一条发送给用户的消息...        
           Mail::assertSent(OrderShipped::class, function ($mail) use ($user) { 
                      return $mail->hasTo($user->email) &&                   
                      $mail->hasCc('...') &&                   
                      $mail->hasBcc('...');     
                   });        
             // 断言邮件被发送两次...     
           Mail::assertSent(OrderShipped::class, 2);       
           // 断言没有发送邮件...        
           Mail::assertNotSent(AnotherMailable::class);   
           }
        }

Scoped 事件模拟

如果你只想为部分测试模拟事件监听，则可以使用 fakeFor

Mail::assertQueued(...);
Mail::assertNotQueued(...);
