Illuminate\Queue\CallQueuedHandler uses a non existent function in Illuminate\Contracts\Bus\Dispatcher

[Naouak]

• Laravel Version: 5.5.32
• PHP Version: Irrelevant
• Database Driver & Version: Irrelevant

Description:

framework/src/Illuminate/Queue/CallQueuedHandler.php

Line 70 in f50e200

$handler = $this->dispatcher->getCommandHandler($command) ?: null;

In this file, $this->dispatcher is an instance of Illuminate\Contracts\Bus\Dispatcher.
Illuminate\Contracts\Bus\Dispatcher has no method getCommandHandler defined so when mockery create a mock of the dispatcher, the function getCommandHandler is not available.
You get this error:

BadMethodCallException : Method Mockery_0_Illuminate_Contracts_Bus_Dispatcher::getCommandHandler() does not exist on this mock object
 /var/www/html/vendor/laravel/framework/src/Illuminate/Queue/CallQueuedHandler.php:70
 /var/www/html/vendor/laravel/framework/src/Illuminate/Queue/CallQueuedHandler.php:49
 /var/www/html/vendor/laravel/framework/src/Illuminate/Queue/Jobs/Job.php:76

Steps To Reproduce:

This test generates the error.

<?php

class BuggyListener implements \Illuminate\Contracts\Broadcasting\ShouldBroadcast
{
    public function broadcastOn()
    {
        return [];
    }
}

class LaravelBugTest extends Illuminate\Foundation\Testing\TestCase
{
    public function testBug()
    {
        $this->expectsJobs([]);
        event(new BuggyListener());
    }

    public function createApplication()
    {
        $app = require __DIR__.'/../bootstrap/app.php';
        $app->make('Illuminate\Contracts\Console\Kernel')->bootstrap();

        return $app;
    }
}

It's just that the contract is missing a few methods, feel free to send a PR on 5.6 to add the missing methods.

I'm currently getting the same error: BadMethodCallException : Method Mockery_0_Illuminate_Contracts_Bus_Dispatcher::getCommandHandler() does not exist on this mock object

I've upgraded to version 5.6.26. What's weird to me is that I can use the expectsJobs in another context where I use "dispatch" directly, but it's failing in this context where I'm expecting it to be fired as a reaction from an event.

I was also getting this error on Laravel 5.3:

BadMethodCallException : Method Mockery_0_Illuminate_Contracts_Bus_Dispatcher::getCommandHandler() does not exist on this mock object

I'm not able to upgrade the Laravel version to 5.6 right now so I implemented a workaround by overriding the withoutJobs() method on TestCase to use a custom Dispatcher interface which includes the missing method signatures.

TestCase

.6.26. What's weird to me is that I can use the expectsJobs in another context where I use "dispatch" directly, but it's failing in this context where I'm expecting it to be fired as a reaction from an event.

Did you find a solution for this one?

I did! Finally. And I made a pull request to boot! (Which is linked above)
