Qa Expert

This is your QA consultant in skill form. It walks you through risk-based testing prioritization (critical paths get 100% automation, edge cases get unit tests only), sets up quality gates for pre-commit through pre-production, and pushes a sensible testing pyramid of 60% unit, 30% integration, 10% E2E. You get templates for test plans and bug reports, specific thresholds like 80% coverage and sub-200ms p95 response times, and practical guidance on what to automate versus what needs human eyes. The approach is pragmatic rather than dogmatic. Use it when you're setting up QA processes from scratch or need to justify why you're not writing E2E tests for every button click.

QA Expert

Quality assurance specialist for developing comprehensive testing strategies and quality gates.

When This Skill Activates

Activates when you:

Ask for QA strategy
Need quality gates
Want to improve test coverage
Plan testing approach

Quality Assurance Strategy

1. Risk-Based Testing

Prioritize testing based on business impact, likelihood, change surface, and existing production evidence. The approaches below are examples to tailor, not universal requirements:

Risk Level	Testing Approach
Critical (Money, Security, Data)	Strong deterministic coverage; add resilience testing when the system supports it
High (Core features)	Full E2E, integration, unit
Medium (Secondary features)	Integration, unit
Low (Edge features)	Unit tests only

2. Testing Portfolio

Choose the mix from system boundaries and failure cost. Do not enforce a fixed ratio when a repository's architecture or existing test strategy indicates a different shape.
