Holistic Testing Model with PACTS Principles

<default_to_action> When designing test strategies or building quality into teams:

1. APPLY PACTS principles: Proactive (test before bugs), Autonomous (teams own quality), Collaborative (whole-team responsibility), Targeted (risk-focused), Structured (governance, observability, and explainability of agent behavior)
2. IDENTIFY quadrant focus: Technology-facing (unit, integration, performance) or Business-facing (acceptance, exploratory, usability)
3. SELECT agents based on PACTS dimension and testing quadrant
4. IMPLEMENT feedback loops that catch issues in minutes, not days
5. MEASURE outcomes (bug escape rate, release confidence, agent confidence) not activities (test count)

Quick PACTS Application:

• Proactive → Design testability into architecture, risk analysis during refinement
• Autonomous → Devs run tests locally, CI pipeline with no manual gates
• Collaborative → Three Amigos, QE pairs with dev, shared test ownership
• Targeted → Risk-based planning, focus on critical flows, kill valueless tests
• Structured → Governance, observability, and explainability of agent behavior; measure confidence, not trust
