# Pest Testing in Krayin CRM

## When to Apply

Activate this skill when:
- Creating or updating tests (unit or feature)
- Debugging test failures
- Using datasets, mocks, or custom expectations
- Writing architecture or convention tests
- The user mentions test, spec, TDD, expects, assertion, coverage, or verifying behavior

## Krayin Testing Structure

### Test Locations

Krayin tests are stored in the root `tests/` directory:

```
/tests
├── Feature/
├── Unit/
├── Pest.php
├── TestCase.php
└── CreatesApplication.php
```

### Available Test Suites

Defined in `phpunit.xml`:

| Test Suite | Location | Command |
|------------|----------|---------|
| Unit | `tests/Unit` | `php artisan test --testsuite="Unit"` |
| Feature | `tests/Feature` | `php artisan test --testsuite="Feature"` |

## Pest.php Configuration

`tests/Pest.php` binds the base test case for feature tests:

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

It also defines helper functions you can reuse, such as:
- `getDefaultAdmin()`
- `actingAsSanctumAuthenticatedAdmin()`
- `getFirstName($fullName)`

## Running Tests

### Run All Tests

```bash
php artisan test --compact
```

### Run a Specific Test Suite

```bash
php artisan test --testsuite="Feature"
php artisan test --testsuite="Unit"
```

### Run a Specific Test File

```bash
php artisan test --compact tests/Feature/ExampleTest.php
```

### Run with Filter

```bash
php artisan test --compact --filter=testName
```

## Creating New Tests

### Create Feature Test

```bash
php artisan make:test --pest ExampleFeatureTest
```

### Create Unit Test

```bash
php artisan make:test --pest --unit ExampleUnitTest
```

## Basic Test Structure

```php
it('passes basic assertion', function () {
    expect(true)->toBeTrue();
});

it('returns successful response', function () {
    $response = $this->get('/');

    $response->assertSuccessful();
});
```

## Assertions

Prefer specific response helpers:

| Use | Instead of |
|-----|------------|
| `assertSuccessful()` | `assertStatus(200)` |
| `assertNotFound()` | `assertStatus(404)` |
| `assertForbidden()` | `assertStatus(403)` |

## Datasets

```php
it('has valid emails', function (string $email) {
    expect($email)->toContain('@');
})->with([
    'james' => 'james@krayin.com',
    'john'  => 'john@krayin.com',
]);
```

## Common Pitfalls

- Forgetting to use `assertSuccessful()` and other specific helpers
- Skipping `--pest` when creating tests
- Ignoring helper utilities already available in `tests/Pest.php`

## Testing Best Practices

- Cover happy paths, failure paths, and edge cases
- Keep tests isolated and focused
- Use factories where available
- Follow existing test patterns in the repository
