visual-parity-testing

Automated visual parity testing is achieved by capturing and comparing screenshots from both production and local environments using Playwright, generating detailed reports for visual consistency checks.

UI consistency across viewports is validated through responsive design checks that verify layout, spacing, typography, and component presence, ensuring that user interfaces remain consistent and avoiding costly errors.

Visual regression testing includes copy and SEO verification to ensure that visible text and SEO metadata match production, providing an evidence-driven workflow for comprehensive visual parity.

Side-by-side comparison of production and local UIs is performed by capturing screenshots with the `/test.parity.capture-all` command and then comparing them using `/test.parity.compare` to validate visual consistency.

Playwright is required for cross-environment screenshot comparisons because it provides the underlying UI automation necessary to capture screenshots and execute the visual parity tests effectively.

Visual parity checks cannot be performed without access to both production and local environment URLs, as the automated workflow requires capturing screenshots from both environments to generate accurate comparison reports.
