…#1300) * Add KB structure and pytest-dev skill Create knowledge base structure for GPU operator: - kb_source/common/skills/ - Common skills for all agents - Added pytest-dev.md - Specialized pytest development agent - Added README.md documenting skills and structure The pytest-dev skill provides: - Test writing following project patterns - Debugging from CI job logs - Test infrastructure navigation - Cross-platform testing (K8s + OpenShift) - Supports gpu-operator, exporter, gpu-dra, and amd-metrics-exporter Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * Enhance pytest-dev skill with component-specific sections Add detailed component-specific testing patterns for: - GPU Operator Helm Chart - Overall deployment and lifecycle - Config Manager - GPU partitioning (SPX, DPX, QPX, CPX, NPS) - Metrics Exporter - Prometheus integration and metric validation - Device Plugin - GPU resource allocation to pods - Node Problem Detector (NPD) - Health monitoring and conditions - Node Remediation (ANR) - Argo Workflows for auto-remediation - Test Runner - RVS validation suite execution - DRA Driver - Dynamic Resource Allocation - Node Labeller - Automatic GPU-based node labeling - Standalone Tests - Debian and Docker deployments Each section includes: - File locations and key utilities - Component purpose and features tested - Key concepts and patterns - Common test structure examples - Integration points with other components This makes the skill more actionable for component-specific development and debugging. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * Restructure testing skills: separate test planning from implementation Split pytest development into two-stage workflow: 1. **test-plan-dev** skill - PRD analysis and test plan generation - Analyzes PRDs and extracts testable requirements - Creates structured test plans with scenario mapping - Defines test coverage matrix and priorities - Generates reviewable documents for stakeholder approval - Output: Test plan (NO code implementation) 2. **pytest-dev** skill - Testcase implementation - Implements actual pytest code from approved test plans - Writes test functions, fixtures, and utilities - Debugs test failures and maintains test infrastructure - Updated to clarify it works AFTER plan approval Benefits: - Clear separation of concerns (planning vs implementation) - Stakeholder review before coding begins - Better alignment with development workflow - Prevents wasted effort on unapproved test strategies Workflow: PRD → /test-plan-dev → review/approve → /pytest-dev → implement Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * Add test plan for ECC deferred error metrics feature Generated comprehensive test plan from PRD-GPU-20260406-01 using test-plan-dev skill approach. Test Plan Highlights: - 20 test scenarios covering all PRD requirements - Requirements traceability matrix (16 testable requirements) - Test priorities: 8 P0 (blocker), 8 P1 (critical), 4 P2 (normal) - Platform coverage: MI2xx, MI3xx, baremetal, SR-IOV - Test coverage matrix by component, platform, deployment Key Test Areas: - Functional: All 19 metrics collection and naming validation - Accuracy: Exact match validation vs AMD-SMI (zero tolerance) - Configuration: Enable/disable and selective field filtering - Platform: MI210, MI250X, MI300X, MI325X support - Error Injection: metricsclient-based validation - Multi-GPU: Independent metrics per GPU/partition - Negative: Unsupported platforms, invalid configs Test Execution Strategy: - P0 tests (8 scenarios) in pre-merge CI - 10-15 min - Full suite (20 scenarios) in nightly regression - 30-45 min - Automated pytest tests in gpu-operator test infrastructure Next Steps: 1.
