# Testing Patterns

**Analysis Date:** 2026-05-28

## Test Framework

**Runner:**
- PHPUnit `^11.5.3` (installed via Composer)
- Config: `src/phpunit.xml`

**Assertion Library:**
- PHPUnit native assertions (`$this->assertTrue()`, `$this->assertSame()`, `$this->assertNull()`, `$this->assertGuest()`)
- Laravel test response assertions (`$response->assertStatus()`, `$response->assertOk()`, `$response->assertSessionHasNoErrors()`, `$response->assertRedirect()`, `$response->assertSessionHasErrorsIn()`)

**Mocking:**
- Mockery `^1.6` available as dependency
- No mock usage detected in existing tests

**Run Commands:**
```bash
composer test              # Runs: php artisan config:clear --ansi && php artisan test
./vendor/bin/phpunit       # Direct PHPUnit invocation
```

## phpunit.xml Configuration

**File:** `src/phpunit.xml`

**Key settings:**
- `colors="true"` — colored output
- `bootstrap="vendor/autoload.php"`
- Test suites: `Unit` (`tests/Unit`) and `Feature` (`tests/Feature`)
- Source inclusion: `app` directory
- Environment overrides:
  - `APP_ENV=testing`
  - `DB_CONNECTION=sqlite`
  - `DB_DATABASE=:memory:` — in-memory SQLite for tests
  - `CACHE_STORE=array`
  - `SESSION_DRIVER=array`
  - `MAIL_MAILER=array`
  - `QUEUE_CONNECTION=sync`
  - `BCRYPT_ROUNDS=4` — faster password hashing
  - `BROADCAST_CONNECTION=null`
  - `PULSE_ENABLED=false`, `TELESCOPE_ENABLED=false`, `NIGHTWATCH_ENABLED=false`

## Test File Organization

**Location:**
- Feature tests: `src/tests/Feature/`
- Unit tests: `src/tests/Unit/`

**Naming:**
- PascalCase class names matching the tested resource: `ExampleTest`, `ProfileTest`, `AuthenticationTest`
- Method names: snake_case descriptive names: `test_the_application_returns_a_successful_response`, `test_profile_page_is_displayed`
- Method prefix: `test_` prefix convention

**Directory Structure:**
```
tests/
├── Feature/
│   ├── Auth/
│   │   ├── AuthenticationTest.php       (empty)
│   │   ├── EmailVerificationTest.php     (empty)
│   │   ├── PasswordConfirmationTest.php  (empty)
│   │   ├── PasswordResetTest.php         (empty)
│   │   ├── PasswordUpdateTest.php        (empty)
│   │   └── RegistrationTest.php          (empty)
│   ├── ExampleTest.php
│   └── ProfileTest.php
├── Unit/
│   └── ExampleTest.php
└── TestCase.php
```

**Base class:** `src/tests/TestCase.php`
```php
namespace Tests;
use Illuminate\Foundation\Testing\TestCase as BaseTestCase;

abstract class TestCase extends BaseTestCase
{
    //
}
```
- Extends `Illuminate\Foundation\Testing\TestCase`
- Empty — no custom setup or helper methods defined
- All Feature tests extend `Tests\TestCase`

## Test Structure

**Suite Organization:**

Feature tests follow standard Laravel testing patterns:
```php
namespace Tests\Feature;
use App\Models\User;
use Illuminate\Foundation\Testing\RefreshDatabase;
use Tests\TestCase;

class ProfileTest extends TestCase
{
    use RefreshDatabase;

    public function test_profile_page_is_displayed(): void
    {
        $user = User::factory()->create();
        $response = $this
            ->actingAs($user)
            ->get('/profile');
        $response->assertOk();
    }
}
```

Unit tests use plain PHPUnit:
```php
namespace Tests\Unit;
use PHPUnit\Framework\TestCase;

class ExampleTest extends TestCase
{
    public function test_that_true_is_true(): void
    {
        $this->assertTrue(true);
    }
}
```

**Patterns:**
- **Arrange-Act-Assert** structure clearly visible
- Variable names: `$user`, `$response`
- Method return type `: void` consistently used
- Chained HTTP methods: `$this->actingAs($user)->patch('/profile', [...])->assertSessionHasNoErrors()`

## Database Testing

**Approach:**
- In-memory SQLite (`DB_DATABASE=:memory:`) for all tests
- `RefreshDatabase` trait used in `ProfileTest` to migrate schema before each test
- `User::factory()->create()` for creating test users

**ProfileTest database patterns:**
```php
public function test_profile_information_can_be_updated(): void
{
    $user = User::factory()->create();

    $response = $this
        ->actingAs($user)
        ->patch('/profile', [
            'name' => 'Test User',
            'email' => 'test@example.com',
        ]);

    $response
        ->assertSessionHasNoErrors()
        ->assertRedirect('/profile');

    $user->refresh();
    $this->assertSame('Test User', $user->name);
    $this->assertSame('test@example.com', $user->email);
    $this->assertNull($user->email_verified_at);
}

public function test_user_can_delete_their_account(): void
{
    $user = User::factory()->create();
    $response = $this
        ->actingAs($user)
        ->delete('/profile', ['password' => 'password']);

    $response
        ->assertSessionHasNoErrors()
        ->assertRedirect('/');

    $this->assertGuest();
    $this->assertNull($user->fresh());
}
```

Key patterns:
- `$user->refresh()` to reload model from database after update
- `$user->fresh()` to check if record still exists (null after delete)
- `$this->assertGuest()` to verify logout
- `->assertSessionHasErrorsIn('userDeletion', 'password')` for error bag validation

## Fixtures and Factories

**Factory location:** `src/database/factories/UserFactory.php`

**UserFactory:**
```php
class UserFactory extends Factory
{
    protected static ?string $password;

    public function definition(): array
    {
        return [
            'name' => fake()->name(),
            'email' => fake()->unique()->safeEmail(),
            'email_verified_at' => now(),
            'password' => static::$password ??= Hash::make('password'),
            'remember_token' => Str::random(10),
        ];
    }

    public function unverified(): static
    {
        return $this->state(fn (array $attributes) => [
            'email_verified_at' => null,
        ]);
    }
}
```

- Uses `fake()` helper for Faker data generation
- Static `$password` cached to hash only once
- `unverified()` state method for email-unverified users
- No factories exist for `station`, `rainfall`, `waterlevel`, `siren`, or `notification` tables

## Coverage

**Requirements:**
- No coverage target configured in `phpunit.xml`
- No coverage report configuration present
- No CI pipeline detected enforcing coverage thresholds

**View Coverage:**
```bash
./vendor/bin/phpunit --coverage-html coverage/
# or with --coverage-text for terminal output
```

## Test Types

**Unit Tests:**
- 1 file: `tests/Unit/ExampleTest.php`
- Single trivial assertion: `$this->assertTrue(true)`
- Extends `PHPUnit\Framework\TestCase` directly (no Laravel app boot)
- No real unit tests for services, models, or utilities exist

**Feature Tests:**
- 2 populated files + 6 empty files:
  - `ExampleTest.php` — tests `/` returns 200
  - `ProfileTest.php` — 5 tests covering profile page, update, email verification, delete, and wrong-password deletion
  - `tests/Feature/Auth/*Test.php` — 6 files, all **empty** (zero bytes)

**E2E Tests:**
- Not used. No Laravel Dusk or Playwright detected.

## Test Coverage Gaps

**Critical gaps:**

1. **No controller tests:** `RainfallController`, `WaterLevelController`, `AdminController`, `SirenController`, `NotificationController`, `MapController`, `cctvController`, `LocaleController` — zero tests
2. **No API tests:** `Api/StationController`, `Api/AuthController`, `Api/AlertController` — zero tests
3. **No service tests:** `FcmService` — zero tests
4. **No export tests:** `HourlyRainfallExport`, `WaterLevelExport` — zero tests
5. **No middleware tests:** `AdminMiddleware`, `LocalizationMiddleware` — zero tests
6. **No model tests:** `User` model features (casts, fillable, hidden, password reset notification) — zero tests
7. **6 placeholder test files** in `tests/Feature/Auth/` are empty (created by Laravel Breeze scaffold but never populated)

## Common Patterns

**Async Testing:**
- Not applicable — Laravel is synchronous; no async patterns in tests

**Error Testing:**
```php
public function test_correct_password_must_be_provided_to_delete_account(): void
{
    $user = User::factory()->create();

    $response = $this
        ->actingAs($user)
        ->from('/profile')
        ->delete('/profile', [
            'password' => 'wrong-password',
        ]);

    $response
        ->assertSessionHasErrorsIn('userDeletion', 'password')
        ->assertRedirect('/profile');

    $this->assertNotNull($user->fresh());
}
```

Patterns:
- `->from('/profile')` to set previous URL for redirect-back tests
- `assertSessionHasErrorsIn('userDeletion', 'password')` for error bag validation
- `->assertRedirect('/profile')` to check redirect destination
- `$this->assertNotNull($user->fresh())` to verify model was NOT deleted

**Authentication Testing:**
```php
$user = User::factory()->create();
$response = $this
    ->actingAs($user)
    ->get('/profile');
$response->assertOk();
```

**Session Assertions:**
- `assertSessionHasNoErrors()` — no validation errors
- `assertSessionHasErrorsIn('userDeletion', 'password')` — specific error in error bag
- Session flash checked via redirect assertion

## CI Configuration

- No CI pipeline configuration detected (no `.github/workflows/`, `.gitlab-ci.yml`, `Jenkinsfile`, etc.)
- No code quality checks enforced in CI
- No automated test running pipeline detected
