From d4448415bb9bc18f66bef43454b8199689ba45b3 Mon Sep 17 00:00:00 2001 From: John Allen Date: Fri, 14 Nov 2025 14:33:10 -0500 Subject: [PATCH 1/2] test(hardware): add comprehensive integration tests for hardware graph Add extensive integration test suite covering real-world hardware discovery scenarios, performance benchmarking, edge case handling, and reusable test fixtures for hardware graph module. Test coverage includes: - Real system hardware discovery using actual /proc and /sys data - Multi-socket server topologies with NUMA configurations - Cloud provider patterns (AWS c5/m5, GCP n2, Azure D-series) - Storage configurations (NVMe, HDD arrays, mixed storage) - Network topologies (bonding, SR-IOV, virtual interfaces) - Partial failure scenarios with graceful degradation - Edge cases (empty fields, inconsistent data, extreme values) - Performance benchmarks for various system sizes (VM to large server) The test fixtures provide reusable generators for CPU cores, NUMA nodes, disk configurations, and network interfaces to support future test development without duplication.
