SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Reliable testing strategies are difficult to implement consistently across Next.js App Router apps, leading to brittle deployments and missed regressions.

Core Features & Use Cases

Clear testing priorities for critical user flows, business logic, data validation, mutations, and rendering branches.
Structured test organization guidance for unit, integration, and end-to-end tests across features, routes, and server actions.
Naming, writing, and flaky-test rules to improve coverage without sacrificing maintainability.

Quick Start

Create a testing plan that matches the recommended project layout: place unit tests near feature code, maintain a dedicated e2e area, and apply the prioritized rules to new tests.
