Livewire Test Debugging Tips

If you're testing a Livewire component and need to debug validation errors, the last response, the last rendered view, etc., Livewire offers these public properties on the tested component. I find dumping the lastErrorBag handy pretty often!

/** @test */
public method something_works()
{
    $component = Livewire::test(SomeComponent::class)->call('someMethod');
    
    dd(
        $component->lastValidator,
        $component->lastErrorBag,
        $component->lastResponse,
        $component->lastRenderedView,
        $component->lastRenderedDom,
    );
}
