TestBuddy v2: Phase 2 Integration Guide

Overview

app.py is the fully integrated TestBuddy application combining Phase 1 backend (config, history, OCR) with a professional Phase 2 UI:

  • SplashScreen: 900ms auto-timeout on startup
  • HomePage: Dashboard with "+ New Session" button and session lists (recent + all)
  • NewSessionDialog: Create session with name, category (General/Project/Receipt/Invoice), and tags
  • Workbench: Dual-panel editor with image viewer + rich text editor
  • Integration Points:
    • ConfigManager (settings from testbuddy.ini)
    • HistoryManager (persistence to testbuddy_history.json)
    • OCRWorker thread (async Tesseract OCR from clipboard)

Key Features

1. New Session Workflow

Home Page → "+ New Session" → Name/Category/Tags Dialog → Workbench
  • Validates session name (required, max 120 chars)
  • Assigns unique session ID (UUID)
  • Switches to workbench for capture + editing

2. Capture → OCR Flow

Workbench → "📷 Capture" → Launches Snipping Tool → Polls clipboard → OCRWorker → Result in editor
  • Launches Windows Snipping Tool (explorer.exe ms-screenclip:)
  • Polls clipboard every 500ms for image (configurable via clipboard_poll_interval_ms)
  • Runs Tesseract in background thread (non-blocking)
  • Displays OCR result in text editor

3. Session Persistence

Workbench → "💾 Save" → HistoryEntry added to JSON → Home page updated
  • Saves full OCR text to testbuddy_history.json
  • Tags = session name for easy lookup
  • Displays confirmation message
  • Home page lists are refreshed on navigation

4. Session Loading

Home Page → Double-click session → Workbench with text loaded
  • Click recent session (top 5) or all sessions list
  • Text loaded into editor for review/export

5. Export Session

Workbench → "📤 Export" → Text saved to export directory
  • Saves as {session_name}_{timestamp}.txt
  • Default directory: export/ (configurable via testbuddy.ini)
  • Confirms export location

Configuration

All settings are in testbuddy.ini (managed by ConfigManager):

Troubleshooting

"No image found in clipboard"

  • Ensure you copied image to clipboard via Snipping Tool
  • Verify clipboard contains image (not text)

"OCR failed"

  • Check tesseract.exe path in testbuddy.ini
  • Verify Tesseract language pack is installed for chosen language
  • See testbuddy.log for detailed error

Sessions not appearing in Home

  • Check if enable_history = true in testbuddy.ini
  • Verify testbuddy_history.json exists and is valid JSON
  • Check testbuddy.log for load errors

App crashes on startup

  • Ensure all requirements installed: pip install -r requirements.txt
  • Verify Python 3.10+ (PyQt6 requirement)
  • Check that config/history files are readable

Next Steps (Phase 3)

Planned improvements:

  1. Image Viewer Enhancements

    • Zoom in/out controls
    • Pan/scroll for large images
    • OCR bounding boxes overlay

  2. Rich Text Editor Features

    • Undo/Redo (Ctrl+Z / Ctrl+Y)
    • Find & Replace (Ctrl+H)
    • Text formatting (bold, italic, monospace)

  3. Multi-Format Export

    • PDF with image + OCR text
    • Word (.docx) with formatting
    • Markdown with metadata

  4. Batch Processing

    • Process multiple images in sequence
    • Export all sessions as PDF/ZIP

  5. UI Polish

    • Dark mode toggle
    • Custom color schemes
    • Toolbar icon sets

  6. Advanced OCR

    • Tesseract confidence scores
    • Language auto-detection
    • Handwriting recognition

Support

For issues or questions:

  1. Check testbuddy.log for error messages
  2. Review configuration in testbuddy.ini
  3. Ensure dependencies installed: pip install -r requirements.txt
  4. Verify Tesseract binary at C:\Program Files\Tesseract-OCR\tesseract.exe
