Frequently Asked Questions

Question 1

What does technical QA involve for a B2B marketing website?

Accepted Answer

Technical QA for a B2B marketing website covers four major areas: visual quality assurance, functional testing, performance validation, and cross-browser and device compatibility. Visual QA ensures every page matches the approved design across all breakpoints, with pixel-level attention to typography, spacing, colors, and component behavior. Functional testing verifies that all interactive elements work correctly — forms submit and route properly, navigation behaves as expected, CTAs link to correct destinations, and CMS content renders accurately. Performance validation confirms that pages meet Core Web Vitals thresholds and load quickly on real networks. Cross-browser testing covers Chrome, Safari, Firefox, and Edge on desktop, plus Safari on iOS and Chrome on Android for mobile. At Webstacks, QA is not a phase that happens at the end — we test continuously during development and run comprehensive QA passes before staging review and production launch.

Question 2

How does Webstacks test websites across different browsers and devices?

Accepted Answer

We test across a device and browser matrix that covers the platforms your actual visitors use. Our standard testing matrix includes Chrome, Safari, Firefox, and Edge on macOS and Windows desktop environments, plus Safari on iOS and Chrome on Android at multiple device sizes. We use both automated tools and manual testing — automated visual regression testing catches unintended visual changes across pages, while manual testing verifies interactive behaviors, animations, and edge cases that automated tools miss. For responsive testing, we verify at specific breakpoints plus several intermediate widths to catch layout issues that only appear between standard breakpoints. We pay special attention to Safari because its rendering engine handles CSS and JavaScript features differently than Chromium-based browsers, and these differences frequently cause layout or functionality issues. Our testing results are documented with screenshots and specific reproduction steps so issues can be resolved quickly.

Question 3

What is visual regression testing and how does it prevent bugs?

Accepted Answer

Visual regression testing automatically compares screenshots of your website pages against known-good baselines to detect unintended visual changes. When a code change inadvertently affects a component that appears on dozens of pages, visual regression testing catches every affected instance immediately rather than relying on manual review of each page. This is particularly valuable for B2B websites with component-based architectures where a single component change can ripple across the entire site. We capture baseline screenshots at each major breakpoint for all page templates and key pages. When code changes are submitted, the system generates new screenshots and highlights any visual differences. Developers review these differences to confirm they are intentional or identify and fix regressions before they reach production. This provides a safety net that lets the team move quickly without fear of accidentally breaking existing pages.

Question 4

How do you QA content entered by marketing teams in the CMS?

Accepted Answer

Content QA is an often-overlooked area that is critical for B2B websites where content quality directly affects credibility with buyers. We address content quality at multiple levels. First, CMS field validation prevents common issues at the point of entry — character limits on titles and meta descriptions, required alt text for images, and content type constraints on rich text fields. Second, our components are designed to handle variable content lengths gracefully, so a heading that is longer or shorter than the design spec does not break the layout. Third, we build preview environments that let content editors see their work in the real page context before publishing. For sites with high content velocity, we can implement automated content checks that flag potential issues like missing metadata, broken internal links, or images without proper sizing. We also provide content entry guidelines that document best practices for each content type so editors understand how to create content that renders well.

Question 5

Does Webstacks perform accessibility testing?

Accepted Answer

Yes, accessibility testing is integrated into our standard QA process, not treated as an optional add-on. We test against WCAG 2.1 Level AA standards, which is the baseline expectation for enterprise B2B websites and a legal requirement in many jurisdictions. Our testing covers keyboard navigation to ensure all interactive elements are reachable and operable without a mouse, screen reader compatibility testing with VoiceOver and NVDA to verify content is properly announced, color contrast verification to ensure text meets minimum contrast ratios, focus indicator visibility for keyboard users, and proper ARIA attributes on interactive components. We use both automated scanning tools that catch programmatic accessibility violations and manual testing that evaluates the actual user experience for people using assistive technologies. Accessibility issues found during QA are treated with the same priority as functional bugs because they affect real users' ability to access your content and convert.
