<objective> Covers Laravel 13 testing with Pest 4 and PHPUnit 12: feature tests (HTTP, full stack), unit tests (isolated classes), and architecture tests; Pest syntax (it/test/describe), datasets; HTTP testing (requests, JSON assertions, auth/actingAs, status/redirect assertions); database testing (RefreshDatabase, factories, DB assertions); mocking (services, spies, Mail/Queue/Event fakes, Http::fake, time travel); console/Artisan command tests; and PHPUnit-attribute-based seeding (#[Seed], #[Seeder]). </objective>

Laravel Testing

Agent Workflow (MANDATORY)

Before ANY implementation, spawn 3 agents in parallel, one `Agent` call each with a `name`:

1. **fuse-ai-pilot:explore-codebase** - Analyze existing test patterns 2. **fuse-ai-pilot:research-expert** - Verify Pest/PHPUnit docs via Context7 3. **mcp__context7__query-docs** - Check assertion and mocking patterns

After implementation, run **fuse-ai-pilot:sniper** for validation.

Overview

| Type | Purpose | Location | |------|---------|----------| | **Feature** | HTTP, full stack | `tests/Feature/` | | **Unit** | Isolated classes | `tests/Unit/` | | **Arch** | Code architecture | `tests/Arch.php` |

Decision Guide: Test Type

What to test?
├── HTTP endpoint → Feature test
├── Service/Policy logic → Unit test
├── Code structure → Arch test
├── External API → Mock with Http::fake()
├── Mail/Queue/Event → Use Fakes
└── Database state → assertDatabaseHas()

---

Decision Guide: Test Strategy

Coverage strategy?
├── Feature tests (70%) → Critical flows
├── Unit tests (25%) → Business logic
├── E2E tests (5%) → User journeys
└── Arch tests → Structural rules

---

Critical Rules

1. **Use RefreshDatabase** for database isolation 2. **Use factories** for test data (never raw inserts) 3. **Mock external services** - Never call real APIs 4. **Test edge cases** - Empty, null, boundaries 5. **Run parallel** - `pest --parallel` for speed

Quick Reference

// Feature test
it('creates a post', function () {
    $user = User::factory()->create();

    $this->actingAs($user)
        ->postJson('/api/posts', ['title' => 'Test'])
        ->assertCreated()
        ->assertJsonPath('data.title', 'Test');

    $this->assertDatabaseHas('posts', ['title' => 'Test']);
});

// With dataset
it('validates emails', function (string $email, bool $valid) {
    // test logic
})->with([
    ['valid@test.com', true],
    ['invalid', false],
]);

// Mock facade
Mail::fake();
// ... action ...
Mail::assertSent(OrderShipped::class);
