Quality Assurance Protocol

Technical QA Framework

Zest Web Solutions' 10-module pre-flight testing protocol for e-commerce storefronts, Shopify builds, and enterprise web platforms.

📋 10 Core Quality Modules 🧪 Multi-Device Hardware Testing 🛡️ Pre-Staging Verification
Module 01

1. Code Quality & Hygiene

Why This Step Matters

Unlinted, bloated code causes memory leaks, unexpected rendering bugs, and high maintenance costs. Peer reviews and static analysis guarantee clean, modular code hygiene.

✔ 0 Shopify Theme Check CLI linting warnings.
✔ Liquid 2.0 {% render %} scope isolation enforced.
✔ ESLint & Stylelint automated CI/CD pass.
✔ Mandatory 2-engineer peer pull request review signoff.
Module 02

2. Performance Testing & Core Web Vitals

Why This Step Matters

Slow page load speeds increase bounce rates and reduce e-commerce conversion rates. Core Web Vitals audits ensure storefronts pass Google speed benchmarks.

✔ Largest Contentful Paint (LCP) < 800ms verified.
✔ Cumulative Layout Shift (CLS) = 0.00 reserved containers.
✔ Interaction to Next Paint (INP) < 150ms.
✔ Total page payload < 1.2MB and CSS bundle < 50KB.
Module 03

3. Accessibility (WCAG 2.1 AA)

Why This Step Matters

Web accessibility guarantees equal access for users with disabilities while protecting brands against ADA compliance lawsuits.

✔ Visible keyboard :focus-visible focus indicator rings.
✔ Full keyboard tab navigation across drawers and modals.
✔ Minimum 4.5:1 text color contrast ratio pass.
✔ Semantic ARIA landmarks and screen reader label tests.
Module 04

4. Fluid Responsive UI Testing

Why This Step Matters

Over 60% of e-commerce traffic originates on mobile devices. Fluid responsive layouts prevent broken viewports and clipped touch targets.

✔ Fluid scaling from 320px mobile to 2560px ultra-wide.
✔ 0 horizontal page scroll overflow across all viewports.
✔ Touch target sizes ≥ 44x44px for thumb tap accuracy.
✔ Dynamic responsive image rendering (`srcset` / ``).
Module 05

5. Cross-Browser & Hardware Compatibility

Why This Step Matters

CSS rendering engines differ between Apple WebKit (Safari) and Chromium/Gecko. Physical hardware matrix testing prevents device-specific rendering failures.

✔ Chrome, Safari, Firefox, and Edge engine validation.
✔ Physical hardware testing on iOS, Android, macOS, Windows.
✔ BrowserStack visual regression test signoff.
✔ Safari iOS form input & video autostart verification.
Module 06

6. Technical SEO Validation

Why This Step Matters

Indexing errors, broken redirects, or canonical loops destroy organic search rankings during redesigns and platform migrations.

✔ 100% self-referential canonical product URLs verified.
✔ Customized `robots.txt.liquid` disallowing tag search loops.
✔ 100% legacy 301 URL redirect map pass.
✔ Dynamic XML sitemap indexability and robots meta tag check.
Module 07

7. Structured Data Validation

Why This Step Matters

Structured data enables Google Merchant Center rich snippets and provides LLMs with accurate entity graphs for AI search citations.

✔ Unbranded video SOP walkthrough handoff (Loom).
Module 10

10. Post-Launch Monitoring & SLAs

Why This Step Matters

Real-time post-launch monitoring catches unexpected 404 errors, DNS propagation issues, or server load spikes before they impact revenue.

✔ Real-time Google Search Console 404 crawl error logging.
✔ Sub-5-minute automated uptime ping monitoring.
✔ 60 days complimentary post-launch bug coverage active.
