+**Do not edit this file.** Agents must never add, remove, or reword anything here. If a change seems needed, say so and let a human do it.
+
+## Ask before testing
+
+When asked to review code or build a feature, do not run the test suite and do not write new tests. Make the change, report it, then ask the user whether tests should be added — describing the tests you have in mind — and wait for the user to confirm.
+
+Two reasons this matters here: the suite takes minutes, and `tests/.snapshots/success.txt` plus the tally in `tests/Visual/Parallel.php` encode the whole suite's result, so a single added test breaks both.
+
+Once the user confirms:
+
+```bash
+composer test:unit         # fast, excludes the visual group
+composer test:integration  # visual and snapshot tests
+composer test              # everything CI runs, in CI's order
+composer update:snapshots  # only when a test was added or removed
+```

+description: "Use this skill for Pest PHP testing in Laravel projects only. Trigger whenever any test is being written, edited, fixed, or refactored — including fixing tests that broke after a code change, adding assertions, converting PHPUnit to Pest, adding datasets, and TDD workflows. Always activate when the user asks how to write something in Pest, mentions test files or directories (tests/Feature, tests/Unit, tests/Browser), or needs browser testing, smoke testing multiple pages for JS errors, architecture tests, or faster test runs with Test Impact Analysis. Covers: test()/it()/expect() syntax, datasets, mocking, browser testing (visit/click/fill), smoke testing, arch(), Livewire component tests, RefreshDatabase, Tia (--tia), sharding, and all Pest 5 features. Do not use for factories, seeders, migrations, controllers, models, or non-test PHP code."

+# Pest Testing 5
+
+## Documentation
+
+Use `search-docs` for detailed Pest 5 patterns and documentation.
+
+## Basic Usage
+
+### Creating Tests
+
+All tests must be written using Pest. Use `{{ $assist->artisanCommand('make:test --pest {name}') }}`.
+
+The `{name}` argument should include only the path and test name, but should not include the test suite.
+- Incorrect: `{{ $assist->artisanCommand('make:test --pest Feature/SomeFeatureTest') }}` will generate `tests/Feature/Feature/SomeFeatureTest.php`
+- Correct: `{{ $assist->artisanCommand('make:test --pest SomeControllerTest') }}` will generate `tests/Feature/SomeControllerTest.php`
+- Incorrect: `{{ $assist->artisanCommand('make:test --pest --unit Unit/SomeServiceTest') }}` will generate `tests/Unit/Unit/SomeServiceTest.php`
+- Correct: `{{ $assist->artisanCommand('make:test --pest --unit SomeServiceTest') }}` will generate `tests/Unit/SomeServiceTest.php`
+
+### Test Organization
+
+- Unit/Feature tests: `tests/Feature` and `tests/Unit` directories.
+- Browser tests: `tests/Browser/` directory.
+- Do NOT remove tests without approval - these are core application code.
+
+### Basic Test Structure
+
+Pest supports both `test()` and `it()` functions. Before writing new tests, check existing test files in the same directory to match the project's convention. Use `test()` if existing tests use `test()`, or `it()` if they use `it()`.
+
+@boostsnippet("Basic Pest Test Example", "php")
+it('is true', function () {
+    expect(true)->toBeTrue();
+});
+@endboostsnippet
+
+### Running Tests
+
+- Run minimal tests with filter before finalizing: `{{ $assist->artisanCommand('test --compact --filter=testName') }}`.
+- Run all tests: `{{ $assist->artisanCommand('test --compact') }}`.
+- Run file: `{{ $assist->artisanCommand('test --compact tests/Feature/ExampleTest.php') }}`.
+- Run only tests affected by recent changes (Tia): `./vendor/bin/pest --parallel --tia`.
+
+## Assertions
+
+Use specific assertions (`assertSuccessful()`, `assertNotFound()`) instead of `assertStatus()`:
+
+@boostsnippet("Pest Response Assertion", "php")
+it('returns all', function () {
+    $this->postJson('/api/docs', [])->assertSuccessful();
+});
+@endboostsnippet
+
+| 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.):
+
+@boostsnippet("Pest Dataset Example", "php")
+it('has emails', function (string $email) {
+    expect($email)->not->toBeEmpty();
+})->with([
+    'james' => 'james@laravel.com',
+    'taylor' => 'taylor@laravel.com',
+]);
+@endboostsnippet
+
+## Pest 5 Features
+
+| Feature | Purpose |
+|---------|---------|
+| Tia (Test Impact Analysis) | Rerun only tests affected by recent changes |
+| Time-Balanced Sharding | Split tests across CI shards by execution time |
+| New Validation Expectations | `toBeEmail()`, `toBeUlid()`, `toBeIpAddress()`, and more |
+| Browser Testing | Full integration tests in real browsers |
+| Smoke Testing | Validate multiple pages quickly |
+| Visual Regression | Compare screenshots for visual changes |
+| Architecture Testing | Enforce code conventions |
+
+### Tia (Test Impact Analysis)
+
+Tia reruns only tests affected by recent changes and replays cached results for the rest, dramatically reducing suite duration:
+
+@boostsnippet("Tia Example", "shell")
+./vendor/bin/pest --parallel --tia
+@endboostsnippet
+
+- Replayed tests are not skipped — cached tests store everything they produced, including covered lines and branches.
+- Detects Laravel, Symfony, Livewire, and Inertia automatically.
+
+### New Validation Expectations
+
+Pest 5 ships eight new validation matchers, all supporting `.not` negation:
+
+@boostsnippet("Pest 5 Validation Expectations", "php")
+expect('nuno@pestphp.com')->toBeEmail();
+expect('01ARZ3NDEKTSV4RRFFQ69G5FAV')->toBeUlid();
+expect('192.168.1.1')->toBeIpAddress();
+expect('00:1a:2b:3c:4d:5e')->toBeMacAddress();
+expect('example.com')->toBeHostname();
+expect('example.co.uk')->toBeDomain();
+expect('Zm9vYmFy')->toBeBase64();
+expect('deadbeef')->toBeHexadecimal();
+@endboostsnippet
+
+### Time-Balanced Sharding
+
+Distribute tests across CI shards by execution time rather than count:
+
+@boostsnippet("Pest Sharding Example", "shell")
+./vendor/bin/pest --update-shards
+./vendor/bin/pest --shard=1/4
+@endboostsnippet
+
+Commit `tests/.pest/shards.json` to the repository so CI shards stay consistent.
+
+### Browser Test Example
+
+Browser tests run in real browsers for full integration testing:
+
+- Browser tests live in `tests/Browser/`.
+- Use Laravel features like `Event::fake()`, `assertAuthenticated()`, and model factories.
+- Use `RefreshDatabase` for clean state per test.
+- Interact with page: click, type, scroll, select, submit, drag-and-drop, touch gestures.
+- Test on multiple browsers (Chrome, Firefox, Safari) if requested.
+- Test on different devices/viewports (iPhone 14 Pro, tablets) if requested.
+- Switch color schemes (light/dark mode) when appropriate.
+- Take screenshots or pause tests for debugging.
+
+@boostsnippet("Pest Browser Test Example", "php")
+it('may reset the password', function () {
+    Notification::fake();
+
+    $this->actingAs(User::factory()->create());
+
+    $page = visit('/sign-in');
+
+    $page->assertSee('Sign In')
+        ->assertNoJavaScriptErrors()
+        ->click('Forgot Password?')
+        ->fill('email', 'nuno@laravel.com')
+        ->click('Send Reset Link')
+        ->assertSee('We have emailed your password reset link!');
+
+    Notification::assertSent(ResetPassword::class);
+});
+@endboostsnippet
+
+### Smoke Testing
+
+Quickly validate multiple pages have no JavaScript errors:
+
+@boostsnippet("Pest Smoke Testing Example", "php")
+$pages = visit(['/', '/about', '/contact']);
+
+$pages->assertNoJavaScriptErrors()->assertNoConsoleLogs();
+@endboostsnippet
+
+### Visual Regression Testing
+
+Capture and compare screenshots to detect visual changes.
+
+### Architecture Testing
+
+@boostsnippet("Architecture Test Example", "php")
+arch('controllers')
+    ->expect('App\Http\Controllers')
+    ->toExtendNothing()
+    ->toHaveSuffix('Controller');
+@endboostsnippet
+
+## 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
+- Forgetting `assertNoJavaScriptErrors()` in browser tests
+- Prefixing `Feature/` or `Unit/` in `{name}` when using `make:test`
