# FilamentPHP Testing Skill

## Overview

This skill generates comprehensive Pest tests for FilamentPHP v4 components following official testing documentation patterns.

## Documentation Reference

**CRITICAL:** Before generating tests, read:
- `/home/mwguerra/projects/mwguerra/claude-code-plugins/filament-specialist/skills/docs/references/general/10-testing/`

## Test Setup

### Base Test Configuration

```php
<?php

declare(strict_types=1);

namespace Tests;

use Illuminate\Foundation\Testing\TestCase as BaseTestCase;

abstract class TestCase extends BaseTestCase
{
    use CreatesApplication;

    protected function setUp(): void
    {
        parent::setUp();

        // Login as admin for Filament tests
        $this->actingAs(\App\Models\User::factory()->create([
            'is_admin' => true,
        ]));
    }
}
```

### Pest Configuration

```php
// tests/Pest.php
uses(Tests\TestCase::class)
    ->in('Feature');

uses(Illuminate\Foundation\Testing\RefreshDatabase::class)
    ->in('Feature');
```

## Resource Tests

### List Page Tests

```php
<?php

declare(strict_types=1);

use App\Filament\Resources\PostResource;
use App\Filament\Resources\PostResource\Pages\ListPosts;
use App\Models\Post;
use App\Models\User;
use Filament\Actions\DeleteAction;
use Filament\Tables\Actions\DeleteBulkAction;

use function Pest\Livewire\livewire;

beforeEach(function () {
    $this->user = User::factory()->create(['is_admin' => true]);
    $this->actingAs($this->user);
});

it('can render the list page', function () {
    livewire(ListPosts::class)
        ->assertSuccessful();
});

it('can list posts', function () {
    $posts = Post::factory()->count(10)->create();

    livewire(ListPosts::class)
        ->assertCanSeeTableRecords($posts);
});

it('can render post title column', function () {
    Post::factory()->create(['title' => 'Test Post Title']);

    livewire(ListPosts::class)
        ->assertCanRenderTableColumn('title');
});

    livewire(ListPosts::class)
        ->sortTable('title')
        ->assertCanSeeTableRecords($posts->sortBy('title'), inOrder: true)
        ->sortTable('title', 'desc')
        ->assertCanSeeTableRecords($posts->sortByDesc('title'), inOrder: true);
});

it('can filter posts by status', function () {
    $publishedPost = Post::factory()->create(['status' => 'published']);
    $draftPost = Post::factory()->create(['status' => 'draft']);

    livewire(ListPosts::class)
        ->filterTable('status', 'published')
        ->assertCanSeeTableRecords([$publishedPost])
        ->assertCanNotSeeTableRecords([$draftPost]);
});

    $posts = Post::factory()->count(3)->create();

    livewire(ListPosts::class)
        ->callTableBulkAction(DeleteBulkAction::class, $posts);
