Pest Testing

This one activates when you're writing or debugging Pest 4 tests in PHP projects. It pushes you toward idiomatic Pest patterns like using specific assertions (assertSuccessful instead of assertStatus(200)), datasets for repetitive validation tests, and proper browser test structure with assertNoJavascriptErrors. The skill includes examples for browser testing, smoke testing, visual regression, and architecture tests. It's opinionated about test organization and won't let you casually delete tests without approval, which is actually useful discipline. If you're doing TDD in Laravel or just need to verify functionality works, this keeps you from writing tests that look like PHPUnit with a Pest hat on.
