Laravel Pest Test Generator

Grundprinzipien

1. Pest-Syntax (nicht PHPUnit). 2. Arrange-Act-Assert. 3. Ein Assert pro Test.
2. Factories nutzen. 5. RefreshDatabase. 6. Sprechende Namen.

Workflow

1. Scan: Existierende Tests, Models, Controller, Services, Routes, Jobs identifizieren
2. Plan: Test-Prioritäten festlegen (KRITISCH → NÜTZLICH)
3. Infrastruktur: Pest.php, Factories, Test-Helpers prüfen
4. Schreiben: Tests nach Patterns unten
5. Ausführen: php artisan test oder vendor/bin/pest

Test-Prioritäten

Test-Patterns

A) Route/Controller (Feature)

it('returns 200 for published items', function () {
    $item = Item::factory()->published()->create();
    $this->get("/items/{$item->slug}")->assertOk();
});

it('returns 404 for unpublished items', function () {
    $item = Item::factory()->unpublished()->create();
    $this->get("/items/{$item->slug}")->assertNotFound();
});

it('requires auth for admin routes', function () {
    $this->get('/admin')->assertRedirect('/login');
});

B) Service/Business Logic (Unit)

it('calculates tax correctly', function () {
    $service = new TaxService();
    expect($service->calculate(100, 'AT'))->toBe(120.0);
});

C) Model

it('has correct fillable fields', function () {
    $model = new Item();
    expect($model->getFillable())->toContain('title', 'slug');
});

it('scopes to published only', function () {
    Item::factory()->published()->count(2)->create();
    Item::factory()->unpublished()->create();
    expect(Item::published()->count())->toBe(2);
});

D) Job/Queue

it('dispatches notification job', function () {
    Queue::fake();
    $order->markAsPaid();
    Queue::assertPushed(SendInvoiceJob::class);
});

it('handles job chain correctly', function () {
    Queue::fake();
    ProcessPayment::withChain([SendInvoice::class])->dispatch($order);
    Queue::assertPushed(ProcessPayment::class);
});

E) Livewire

it('can search items', function () {
    $item = Item::factory()->create(['title' => 'Unique']);
    Livewire::test(ItemList::class)
        ->set('search', 'Unique')
        ->assertSee('Unique');
});

F) Security

it('prevents unauthorized access', function () {
    $user = User::factory()->create();
    $this->actingAs($user)->get('/admin/users')->assertForbidden();
});

it('validates CSRF on forms', function () {
    $this->post('/contact', ['name' => 'Test'])->assertStatus(419);
});

it('rate limits login attempts', function () {
    for ($i = 0; $i < 6; $i++) {
        $this->post('/login', ['email' => 'a@b.com', 'password' => 'wrong']);
    }
    $this->post('/login', ['email' => 'a@b.com', 'password' => 'wrong'])
        ->assertStatus(429);
});

G) Filament Admin

it('admin can access dashboard', function () {
    $admin = User::factory()->admin()->create();
    $this->actingAs($admin)->get('/admin')->assertOk();
});

Hinweise

• RefreshDatabase für Feature Tests, DatabaseTransactions wenn schneller nötig
• Mail::fake(), Queue::fake(), Notification::fake() für Side-Effects
• Externe APIs (Mollie, VIES) immer mocken
• Factories mit States: ->published(), ->admin(), ->withTeam()
• Ziel: min. 80% Coverage auf Auth, Payment, Business Logic
