What problem does it solve? Running and diagnosing tests across the PaasFabric platform involves many environments (local, KVM servers, nested VMs, CI pipelines) and inconsistent procedures. This Skill unifies all testing into one QA orchestrator with a single API (pre-check → execute → post-check → report), so test runs are reproducible, failures are diagnosed by root cause, and bugs are escalated to the right engineering role instead of being masked with workarounds. ## Core Features & Use Cases - Eight unified test schemes: local (unit/lint), e2e on KVM/KVM2, CI diagnostics via GitHub CLI, nested KVM, K8s matrix, PostgreSQL matrix, VirtMan E2E, and production deploy — all sharing the same report format and artifact storage. - Mandatory pre-checks: verifies pf version consistency, git sync between local and server, pip editable installs, disk space, and Terraform locks before any run, stopping early on divergence. - Root-cause escalation table: maps failure symptoms (Python tracebacks, Ansible fails, Terraform drift, Nexus 503, flaky tests) to the responsible agent such as /platform-engineer, /devops, or /reliability-engineer. - Use Case: After pushing a feature branch, invoke the e2e scheme to monitor CI in parallel with KVM tests, receive a structured pass/fail report, and get an automatic escalation hint when a test fails. ## Quick Start Ask the agent to run the local test scheme with /qa-engineer local, or run the full E2E suite on the KVM server with /qa-engineer e2e kvm.
