Re-engineering Browser QA

Why manual multi-environment testing is fundamentally broken, and how Mirra fixes it.

The Testing Bottleneck

  • Manual comparative testing is slow and repetitive
  • Constant Alt-Tab window switching breaks developer focus
  • Minor visual regressions slip through to production
  • Accessibility checks require opening separate utilities

The Mirra Paradigm

  • Perform actions on Source; Target mirrors instantly
  • Contained dual-viewport keeps both views centered
  • Heatmaps highlight pixel differences automatically
  • Embedded axe-core auditing checks both panels in one click

Product Capabilities

A dashboard of tools designed to streamline environment checks and regression testing.

Synchronized Input Mirroring

Interact with one panel; the other mimics inputs dynamically. Synchronizes cursor mouse coordinates, page scrolls, and form fields via Chrome DevTools Protocol.

Accessibility Audit

Evaluate accessibility guidelines. Flags rules regressions with inline indicators, powered by axe-core.

Axe Accessibility Testing Panel

Heatmap & Overlay

Stack elements transparently or toggle heatmap visual diffs to outline style variances.

Overlay Diffing Mode

Synchronized Console & Network

Isolate runtime problems. Side-by-side debugger outlines network query responses, warnings, and javascript logs. Isolates deviations between panel states.

Mirra Console Output Sync View

Pixel-Perfect Heatmap regression

Spot alignment deviations automatically. Generates pixel-difference mappings highlighting color drifts, margins changes, and content mismatches.

Heatmap Accuracy comparison

Developer Toolkit

Built-in utilities to assist in quick layouts checks and environment auditing.

📐

Smart Ruler

Measure element paddings, margins, and vertical offsets instantly.

📑

Bookmarks

Save staging/production URL pairs to automate daily test cases.

⌨️

Hotkey Macros

Toggle visual modes and synchronization options without touching the mouse.

Built for Speed

Native desktop execution delivering zero input lag.

Core Architecture

WPF + .NET

Engineered as a native Windows desktop app. Bypassing Electron ensures minimal memory use and high-performance UI updates.

Rendering Engine

WebView2 Chromium

Powered by Microsoft Edge WebView2, ensuring 100% rendering parity with modern Google Chrome builds.

Protocol Layer

CDP Event Line

Bypasses standard layout drivers, communicating directly via Chrome DevTools Protocol to mirror inputs instantly.

Target Workflows

How testing teams incorporate Mirra in their release pipelines.

Regression Auditing

Compare v1 vs v2 staging deployments side-by-side to make sure styling elements remain intact.

Environment Matching

Verify local developments match production outputs, finding configuration drifts immediately.

Technology Migration

Benchmark older frameworks alongside Next.js transitions to assert pixel-perfect structure replication.
