Add documentation for Flux testing

[raz-iacob]

It would be good to have some documentation for testing. For example I wanted to test if a modal was closing and eventually I figure it out that I can do

->assertDispatched(
        event: 'modal-close', 
        name: 'add-new'
)

But there are many other cases where I have no idea how to test the Flux components.

What do you guys think?

Good idea. I also had trouble setting a value for the DatePicker component in combination with DateRange in tests.

I was writing a bunch of examples here, but I found the solution while trying out different things. Maybe this can be helpful for others.

If you want to set a DateRange property on a Livewire component in a test, you should set it as an array and not a DateRange object:

it('can set range')->livewire(Component::class)
  // Good
  ->set('range', ['start' => $start, 'end' => $end])
  // Bad
  ->set('range', new DateRange($start, $end));
  ->set('range', [$start, $end])
