Best Practices

1. Test complete workflows - From list to create to edit
2. Test all form fields - Validate each input type
3. Test table features - Search, filter, sort, pagination
4. Test actions - Both row and bulk actions
5. Test authorization - All permission levels
6. Test widgets - Stats and data accuracy
7. Test relation managers - CRUD on related models
8. Use factories - Generate consistent test data
9. Test validation - Both client and server side
10. Test custom pages - Settings and specialized pages

Quality Checklist

• All resource pages tested (List, Create, Edit, View)
• Table features tested (search, filter, sort, pagination)
• All actions tested (row, bulk, custom)
• Form fields validated
• Authorization properly tested
• Widgets display correct data
• Relation managers work correctly
• Custom pages function properly
• Tests use Pest 4 syntax
• All tests pass successfully

Common Test Patterns

Testing Modal Actions

it('can open modal action', function () {
    $post = Post::factory()->create();

    livewire(PostResource\Pages\ListPosts::class)
        ->callTableAction('view', $post)
        ->assertSuccessful()
        ->assertSee($post->title);
});

Testing Form Sections

it('can fill form across multiple sections', function () {
    livewire(PostResource\Pages\CreatePost::class)
        ->fillForm([
            'title' => 'Test Post',
            'content' => 'Content',
            'meta_title' => 'SEO Title',
            'meta_description' => 'SEO Description',
        ])
        ->call('create')
        ->assertHasNoFormErrors();
});

Testing Notifications

it('shows success notification after save', function () {
    $post = Post::factory()->create();

    livewire(PostResource\Pages\EditPost::class, [
        'record' => $post->getRouteKey(),
    ])
        ->fillForm(['title' => 'Updated Title'])
        ->call('save')
        ->assertNotified('Saved successfully');
});
