Quality Assurance

Quality Assurance

A comprehensive QA skill for building and running effective quality programs: strategy, planning, test design, execution, automation, non-functional coverage, and continuous improvement.

Quick Start

1. Clarify scope, risks, and release criteria.
2. Map test strategy: levels (unit/integration/E2E), types (functional, security, performance, UX), environments, and data.
3. Define quality gates in CI/CD (lint, SAST, tests, coverage, scanning).
4. Plan execution: owners, schedule, entry/exit criteria.
5. Track defects and readiness with metrics; iterate on gaps.

Core Capabilities

1) Strategy & Planning

• Define objectives, scope, and risk-based priorities.
• Choose test types and levels; align to environments and data needs.
• Establish entry/exit criteria, Definition of Ready/Done, and release gates.
• Map dependencies (services, test data, accounts, flags).

2) Test Design

• Create test plans and charters (positive/negative, edge cases).
• Derive cases from requirements, flows, and risk areas.
• Apply heuristics (CRUD, boundaries, state transitions, error paths).
• Specify expected results, data, and observability hooks.

3) Functional Coverage

• Unit coverage for critical logic; integration for contracts/IO; E2E for happy/critical paths.
• Regression suites per component and smoke tests per deploy.
• Data variation: boundaries, locales, timezones, permissions, offline/latency.

4) Non-Functional Coverage

• Performance: baselines, load/stress/soak, SLO/SLA validation.
• Security: authZ/authN, input validation, dependency and secret scanning.
• Reliability: retries, idempotency, backoff, timeouts, circuit breakers.
• Accessibility/UX: WCAG basics (labels, focus, color contrast, keyboard).

5) Automation & Tooling

• CI gates: lint, unit/integration/E2E, coverage thresholds, SAST/DAST/SCA, secret scanning.
• Flake management: quarantine, retry budget, stability tracking.
• Test data: fixtures, factories, seeds, synthetic vs production-like data.
• Reporting: dashboards for pass rate, coverage, defect trends, MTTR/MTRR.

6) Defect Lifecycle & Readiness

• Triage: severity/priority, repro steps, environment, logs/traces.
• Root cause: code, test gap, environment, data, process.
• Exit criteria: critical defects fixed/waived, key scenarios passed, gates green.
• Post-release monitoring: error budgets, alerts, rollback/feature flag plans.

7) Quality Maintenance & Documentation

• Quality handbook: definition of ready/done, severity/priority matrix, gating rules, and escalation paths.
• Living test inventory: traceability from requirements/risks to suites (unit, integration, E2E, non-functional) with owners and status.
• Release/QA checklists: per environment and per release; include gating thresholds, data prep, observability checks, and rollback validation.
• Metrics & reports: coverage, pass rate, flake rate, defect density/escape rate, MTTR/MTRR; publish dashboards and retros.
• Knowledge base: known issues, mitigations, runbooks, and playbooks for incident/rollback/triage.

Workflows

Workflow: Build a QA Plan

1. Identify scope, risks, and success criteria.
2. Choose levels and types of testing; map to environments and data.
3. Define gates (CI checks, coverage thresholds, blocking severity).
4. Assign owners, schedule, and communication cadence.
5. Publish test cases/charters; set defect triage and reporting.
6. Run, track metrics, and iterate on gaps.

Workflow: Defect Triage

1. Verify and minimize repro steps; capture logs, traces, env, data.
2. Classify severity/priority; tag area/owner.
3. Assess impact and escape point; create fix/mitigation.
4. Add regression coverage; update dashboards.

Workflow: Release Readiness

1. Check gates: CI status, coverage thresholds, critical test suites, security scans.
2. Review open defects vs exit criteria; confirm waivers/flags.
3. Validate rollback/feature flags and monitoring in place.
4. Communicate go/no-go with risks and mitigations.
