Testing jobs does not overlap

[xxRockOnxx]

How could this be done if needed?

I have added WithoutOverlapping middleware in my jobs and test them like in the following:

    public function test_should_not_overlap_with_baz()
    {
        // Tried with and without this
        $this->app['config']->set('queue.default', 'database');

        Bus::fake();

        Foo::dispatch($something);
        $this->artisan('queue:work', ['--once' => true])->assertSuccessful();
        Bus::assertDispatched(Foo::class);

        Baz::dispatch($something);
        $this->artisan('queue:work', ['--once' => true])->assertSuccessful();
        Bus::assertNotDispatched(Baz::class);
    }

I'm really not sure if this makes sense. I'm shooting in the dark here but this should get the intent across.

I'm guessing this is failing as intended but I'm trying to assert that Baz does not get handled.

Edit:

The following is a lot closer to what I'm trying to test.

    public function test_should_not_overlap_with_baz()
    {
        Bus::fake();

        Foo::dispatch($something);

        $unhandledJob = (new Baz($something))->withFakeQueueInteractions();

        // Expecting Laravel to handle the job and drop it because of the middleware
        Bus::dispatch($unhandledJob);
        $job->assertDeleted();


        // Also tried spying but this passes even without the middleware
        Mockery::spy($unhandledJob)->shouldReceive('handle')->never();
        Bus::dispatch($unhandledJob);
    }
