Best practice: Testing Nova resources.

How should Laravel Nova resources be tested? Many of the examples i find online test Nova itself rather than the implementation of the developer.

1; What do i want to test?

• I don't trust myself when creating a migration, that Nova resources are being updated correctly.
• Ensuring the right rules are applied to a Nova resource.
• Ensure i'm able to persist the data ( if this isnt testing Nova itself )
• Anything else i might be forgetting, ( policies? )

2; In general, how much/far should you test nova?

3; Practical case; Let's say i have a very simple resource called company:

class Company extends Model
{
	protected $table = 'companies';

	protected $fillable = [
        	'name',
        	'active'
    	];
}

And this is my Nova resource:

class Company extends Resource
{
	public static $model = \App\Models\Company::class;


	public function fields(Request $request)
	{
		return [
			ID::make()->sortable(),

			Text::make('name')
                		->rules('required', 'max:100'),

			Boolean::make('active'),

			Boolean::make('non_existing_field'),

			Date::make('created_at')->readonly(),

			HasMany::make('User'),
        ];
    }
}

I can imagine i'd like to make sure that my name rule is correct, and make sure my non existing field is discovered so i can fix this.

At this point i havent really got a clue how to do this (Let alone in a best practice way). An example or/and an explanation would be very welcome and i hope this helps other people who are looking to start testing nova.

Thanks guys.
