Activates when writing tests, creating unit or feature tests, adding assertions, testing Livewire components, architecture testing, debugging test failures, working with datasets or mocking; or when the user mentions test, spec, TDD, expects, assertion, coverage, or needs to verify functionality works."

+# Pest Testing 3
+
+## When to Apply
+
+Activate this skill when:
+- Creating new tests (unit or feature)
+- Modifying existing tests
+- Debugging test failures
+- Working with datasets, mocking, or test organization
+- Writing architecture tests
+
+## Documentation
+
+Use `search-docs` for detailed Pest 3 patterns and documentation.
+
+## Basic Usage
+
+### Creating Tests
+
+All tests must be written using Pest. Use `php artisan make:test --pest {name}`.
+
+### Test Organization
+
+- Tests live in the `tests/Feature` and `tests/Unit` directories.
+- Do NOT remove tests without approval - these are core application code.
+- Test happy paths, failure paths, and edge cases.
+
+### Basic Test Structure
+
+<!-- Basic Pest Test Example -->
+```php
+it('is true', function () {
+    expect(true)->toBeTrue();
+});
+```
+
+### Running Tests
+
+- Run minimal tests with filter before finalizing: `php artisan test --compact --filter=testName`.
+- Run all tests: `php artisan test --compact`.
+- Run file: `php artisan test --compact tests/Feature/ExampleTest.php`.
+
+## Assertions
+
+Use specific assertions (`assertSuccessful()`, `assertNotFound()`) instead of `assertStatus()`:
+
+<!-- Pest Response Assertion -->
+```php
+it('returns all', function () {
+    $this->postJson('/api/docs', [])->assertSuccessful();
+});
+```
+
+| Use | Instead of |
+|-----|------------|
+| `assertSuccessful()` | `assertStatus(200)` |
+| `assertNotFound()` | `assertStatus(404)` |
+| `assertForbidden()` | `assertStatus(403)` |
+
+## Mocking
+
+Import mock function before use: `use function Pest\Laravel\mock;`
+
+## Datasets
+
+Use datasets for repetitive tests (validation rules, etc.):
+
+<!-- Pest Dataset Example -->
+```php
+it('has emails', function (string $email) {
+    expect($email)->not->toBeEmpty();
+})->with([
+    'james' => 'james@laravel.com',
+    'taylor' => 'taylor@laravel.com',
+]);
+```
+
+## Pest 3 Features
+
+### Architecture Testing
+
+Pest 3 includes architecture testing to enforce code conventions:
+
+<!-- Architecture Test Example -->
+```php
+arch('controllers')
+    ->expect('App\Http\Controllers')
+    ->toExtendNothing()
+    ->toHaveSuffix('Controller');
+
+arch('models')
+    ->expect('App\Models')
+    ->toExtend('Illuminate\Database\Eloquent\Model');
+
+arch('no debugging')
+    ->expect(['dd', 'dump', 'ray'])
+    ->not->toBeUsed();
+```
+
+### Type Coverage
+
+Pest 3 provides improved type coverage analysis. Run with `--type-coverage` flag.
+
+## Common Pitfalls
+
+- Not importing `use function Pest\Laravel\mock;` before using mock
+- Using `assertStatus(200)` instead of `assertSuccessful()`
+- Forgetting datasets for repetitive validation tests
+- Deleting tests without approval
