Holistic Testing Model with PACT Principles

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

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

Quick PACT 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
