Unit Testing

Execute refactoring safely with test-first verification following best practices. Takes refactoring discovery reports as input and performs incremental refactoring with continuous validation. Ensures tests stay green, captures metrics, and generates execution logs. Use after refactoring-discovery analysis to implement recommended improvements. (project, gitignored)

Use when creating reusable composables, managing reactive state, or implementing the Composition API. Load for useX patterns, Pinia store patterns, withLoadingState helper, lifecycle management, and type-safe state patterns. Covers composable structure, error handling, and testing composables.

Playwright E2E testing patterns for TaxHelper. Use for auth redirects, insights drill-down, mobile viewport checks, and PWA verification.

Fast, repeatable UI verification using Puppeteer without paying browser startup per test. Use scenario suites + deterministic fixtures before jumping to full Jest E2E.

Use when implementing any feature or bugfix, before writing implementation code - write the test first, watch it fail, write minimal code to pass; ensures tests actually verify behavior by requiring failure first
