• Mind Map (sidebar) — Root → Suite → Describe → Test, always visible, collapsible
• Individual Test History Cards — one card per test, mini bar chart (last 15 runs) + collapsible run table
• Failure Analysis — auto-classified: Assertion / Timeout / Network / Script

Charts (10 total)

Pass/Fail donut · Duration histogram · Test Volume & Outcome Trends (line) · Execution Duration Trends (area) · Duration by Spec File (bar) · Duration by Describe Block (stacked column) · Worker Distribution (bar) · Browser Distribution (pie) · Top 10 Slowest · Suite Health

History & Trends

• Auto-saved to .history/ — up to 30 runs, ~3 KB each
• Pass rate trend line + run breakdown bar

Architecture — One Change, All Platforms

core/src/template.html   ← ALL UI (edit this to change the report)
core/src/parser.js       ← JUnit XML parser
core/src/history.js      ← History + email
        ↓
node scripts/build.js    ← Compiles to all 3 platforms
        ↓
packages/pip/            → PyPI
packages/npm/            → npmjs.com
packages/maven/          → Maven Central

Making changes:

# Edit core/src/template.html (or parser.js / history.js)
node scripts/build.js          # rebuild all platforms
node scripts/build.js --verify # rebuild + run 24 self-tests

---

Publishing

node scripts/build.js                   # build all 3
npm run publish:pip                     # → PyPI
npm run publish:npm                     # → npmjs.com
cd packages/maven && mvn deploy         # → Maven Central
