EVY Testing Plan

Comprehensive Testing Strategy for Edge Deployment

Document Purpose

This document outlines the complete testing strategy for EVY, covering unit tests, integration tests, hardware tests, and edge-specific testing scenarios. All tests are designed to validate functionality under edge constraints.

Last Updated: [Date] Status: Ready for Implementation Target Hardware: Raspberry Pi 4 (8GB RAM, ARM64)
