I wanna test my livewire store functionality.

public function store()
{
    $validated = $this->validate(
        [
            'service_id' => 'required',
            'price' => 'required|regex:/^[0-9]{1,5}([,.][0-9]{1,2})?$/',
            'option_available.*' => 'boolean',
            'option_price.*' => 'regex:/^[0-9]{1,5}([,.][0-9]{1,2})?$/'
        ]
    );

    // formatting price
    $validated['price'] = (float) str_replace(',' , '.', $validated['price']);

    $service = $this->services->find($validated['service_id']);

    $options = collect([]);

    if ( $this->serviceOptions ) {
        foreach ($this->serviceOptions as $key => $option) {
            $options->push(
                [
                    'name' => $option['name'],
                    'price' => ((float) str_replace(',', '.', $this->option_price[$key]))  * 100 ?? '',
                    'available' => $this->option_available[$key] ?? false
                ]
            );
        }
    }

    $this->garage->addService($service, $options, $validated['price']);
}

This is my test function:

    /** @test */
function user_can_edit_garage_services_information() {

    Role::create(['name' => 'Garage Owner']);

    $garage = factory(Garage::class)->create();

    // create and attach services
    $service = Service::create(
        [
            'name' => 'Reifenwechsel',
            'slug' => 'reifenwechsel'
        ]
    );

    // create and attach service options
    $serviceOptions = collect(
        [
            'name' => 'Wuchten',
            'available' => false,
            'price' => 3
        ]
    );

    $garage->addService($service, $serviceOptions, 20);

    $this->assertEquals(20, $garage->services->first()->pivot->price);
    $this->assertEquals(false, $garage->services->first()->pivot->options['available']);
    $this->assertEquals(3, $garage->services->first()->pivot->options['price']);

    Livewire::test(
        GarageServiceListItem::class,
        [
            'garage' => $garage
        ]
    )
        ->set('service_id', $service->id )
        ->set('price', 25 )
        ->set('option_available.0', true)
        ->set('option_price.0', 5)
        ->call('store');

    $garage->refresh();

    $this->assertEquals(25, $garage->services->first()->pivot->price);
    $this->assertEquals(true, $garage->services->first()->pivot->options['available']);
    $this->assertEquals(5, $garage->services->first()->pivot->options['price']);
}

I get this error exception when trying to test this function:

ErrorException : Undefined index: available

I need to pass the ‘option_available’ and ‘option_price’ values but don’t have the clue how I can do this.

Does anyone know the reason?

Thanks in advance.
