Overview

The Fern Platform web interface has been completely redesigned with a modern, professional UX/UI that incorporates the Fern brand identity and provides powerful data visualization capabilities.

Key Features Implemented

🎨 Brand Identity Integration

  • Fern Green Color Scheme: Primary colors derived from the Fern logo (#7cb342, #43a047, #8bc34a)
  • Nature-Inspired Design: Seedling logo icon and organic color gradients
  • Professional Typography: Inter font family for excellent readability
  • Consistent Design System: CSS custom properties for colors, spacing, shadows, and border radius

🗺️ Treemap Visualization

  • Interactive Test Suite Overview: D3.js-powered treemap showing all projects at a glance
  • Size-Based Representation: Rectangle size proportional to number of tests
  • Intelligent Color Coding:
    • 🟢 Green: High pass rate (90%+) - Excellent test health
    • 🟢 Light Green: Good pass rate (70-89%) - Good test health
    • 🟡 Yellow: Medium pass rate (50-69%) - Needs attention
    • 🟠 Orange: Mixed results - Requires investigation
    • 🔴 Red: High fail rate (70%+) - Critical issues
  • Real-Time Data: Shows current test run statistics (not historical)
  • Responsive Design: Adapts to different screen sizes

📊 Enhanced Navigation & Layout

  • Sticky Header: Always visible with live statistics
  • Tab-Based Navigation: Clean, intuitive page switching
  • Live Statistics: Real-time display of active projects and recent runs

  3. Test Runs: Browse all test execution history with detailed metrics

Design Philosophy

The enhanced UI follows these principles:

  • Clarity: Information is easy to find and understand
  • Efficiency: Common tasks are streamlined
  • Consistency: Uniform patterns throughout the interface
