Building an Automated Testing & Compliance Suite for the Modern Web

Manual testing doesn't scale. QA teams still click through forms by hand, verify layouts on multiple devices one at a time, and run accessibility audits separately from everything else.

We built a suite that does it all in a single pass — and tells you exactly how to fix what's broken.

The Challenge

Existing testing workflows force teams to make a false choice:

  • Accessibility tools catch WCAG violations but don't test UI behavior
  • E2E test frameworks verify user flows but ignore accessibility entirely
  • Media content — video, audio, interactive embeds — rarely gets tested at all
  • Cross-device testing means multiple setups, multiple passes, disconnected reports
  • Violation reports say "something's wrong" but rarely say "here's how to fix it"

The gap was clear: one tool, one pass, one report — covering accessibility, UI, interaction, and media across all device sizes, with fix recommendations that engineers can actually act on.

Our Approach

Unified testing pipeline. Playwright drives a single pass through each page — axe-core checks accessibility in parallel with visual regression checks and functional validations. One execution run produces results for accessibility, UI correctness, and behavioral testing simultaneously. No separate tools, no disconnected reports.

Cross-device execution. The suite runs each test across desktop, tablet, and mobile viewports automatically. Playwright's device emulation handles screen dimensions, touch inputs, and viewport characteristics. A single report aggregates results by device, showing which violations are responsive bugs versus universal issues.

Interaction simulation. The suite doesn't just inspect the DOM — it interacts with it. Automated click paths walk through navigation flows. Form fill sequences validate inputs, error states, and submission behavior. Modal dialogs and overlays are opened, tested for focus trapping, and dismissed. Keyboard-only navigation simulates the assistive tech experience — tab order, focus indicators, and skip links.

Media testing. Puppeteer handles video and audio elements: playback initiation, captions presence, transcript availability, autoplay behavior, and interactive media controls. Elements that are often invisible to accessibility-only scanners get validated here.

AI-powered fix recommendations. For every violation, an AI agent analyzes the context — the element, the page structure, the violation rule — and generates a specific code-level fix suggestion. Not "add alt text" but "add alt=\"Screenshot of dashboard showing Q4 revenue chart\" on line 47." Violations are ranked by severity, grouped by impact, and paired with fix snippets.

Rich reporting. HTML and PDF reports bundle everything — screenshots of each violation with annotations, severity scores, device-specific breakdowns, fix recommendations, and an executive summary with compliance percentages. QA teams get actionable data; stakeholders get a clear picture.

Results

The suite collapses accessibility auditing, UI testing, interaction validation, and media testing into a single automated pass across desktop, tablet, and mobile. What used to require three tools and manual stitching becomes one report. AI-generated fix recommendations turn violations from a list of problems into a list of solutions.
