+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) or architecture tests. Covers: test()/it()/expect() syntax, datasets, mocking, browser testing, arch(), Livewire component tests, RefreshDatabase, and all Pest 3 features. Do not use for editing factories, seeders, migrations, controllers, models, or non-test PHP code."

+# Pest Testing 3
+
+## Documentation
+
+Use `search-docs` for detailed Pest 3 patterns and documentation.
+
+## Basic Usage
+
+### Creating Tests
+
+All tests must be written using Pest. Use `vendor/bin/sail 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
+
+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()`.
+
+<!-- Basic Pest Test Example -->
+```php
+it('is true', function () {
+    expect(true)->toBeTrue();
+});
+```
+
+### Running Tests
+
+- Run minimal tests with filter before finalizing: `vendor/bin/sail artisan test --compact --filter=testName`.
+- Run all tests: `vendor/bin/sail artisan test --compact`.
+- Run file: `vendor/bin/sail 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
