Runbook 08 — Page Objects at scale

This preview outlines the capability introduced by this runbook and the role it plays in the larger automation system.

What this runbook does

Test suites degrade when UI logic is scattered and unstructured. This runbook establishes a layered Page Object Model that isolates UI mechanics, enforces locator discipline, and standardizes how new functionality is added.

• Layered architecture separates pages, components, flows, and assertions
• Locator policy prioritizes accessibility and stability over DOM structure
• Expansion follows a defined procedure that prevents structural drift over time

What it proves

The UI layer becomes a governed system—capable of scaling to larger suites without introducing fragility or maintenance sprawl.

Access

The full runbook includes POM contracts, locator policy, page/component/flow structure, and PR review checks for maintaining scale safely.
