-# TUT Browser Testing Guide
-
-This document provides comprehensive testing instructions to ensure the browser works correctly.
-
-## Quick Start
-
-```bash
-# Build the browser
-cmake -B build -S . -DCMAKE_BUILD_TYPE=Debug
-cmake --build build
-
-# Run with a test site
-./build/tut http://example.com
-
-# Or use the interactive test script
-./test_browser.sh
-```
-
-## Feature Testing Checklist
-
-### Basic Navigation
-- [ ] Browser loads and displays page correctly
-- [ ] Scroll with j/k works smoothly
-- [ ] Page up/down (Ctrl+d/u) works
-- [ ] Go to top (gg) and bottom (G) works
-- [ ] Back (h) and forward (l) navigation works
-
-### Link Navigation
-- [ ] Tab cycles through links
-- [ ] Shift+Tab goes to previous link
-- [ ] Enter follows the active link
-- [ ] Links are highlighted when active
-- [ ] Link URLs shown in status bar
-
-### Search
-- [ ] Press / to enter search mode
-- [ ] Type search term and press Enter
-- [ ] Matches are highlighted
-- [ ] n/N navigate between matches
-- [ ] Search count shown in status bar
-
-### Form Interaction
-- [ ] Press 'i' to focus first form field
-- [ ] Tab/Shift+Tab navigate between fields
-- [ ] Enter on text input enters edit mode
-- [ ] Text can be typed and edited
-- [ ] Backspace removes characters
-- [ ] Enter or Esc exits edit mode
-- [ ] Checkbox toggles with Enter
-- [ ] SELECT dropdown shows options
-- [ ] j/k navigate dropdown options
-- [ ] Enter selects option in dropdown
-- [ ] Selected option displays correctly
-
-### Bookmarks
-- [ ] Press B to bookmark current page
-- [ ] Press D to remove bookmark
-- [ ] Type :bookmarks to view all bookmarks
-- [ ] Bookmarks persist between sessions
-- [ ] Can click bookmarks to open pages
-
-### History
-- [ ] Type :history to view browsing history
-- [ ] History shows URLs and titles
-- [ ] History entries are clickable
-- [ ] History persists between sessions
-- [ ] Recent pages appear at top
-
-### Performance
-- [ ] Page loads are async with spinner
-- [ ] Esc cancels page loading
-- [ ] Page cache works (revisit loads instantly)
-- [ ] Image cache works (images load from cache)
-- [ ] Status shows "cached: N" for cached images
-- [ ] Scrolling is smooth
-- [ ] No noticeable lag in UI
-
-### Commands
-- [ ] :o URL opens new URL
-- [ ] :q quits the browser
-- [ ] :bookmarks shows bookmarks
-- [ ] :history shows history
-- [ ] :help shows help page
-- [ ] ? also shows help page
-
-### Edge Cases
-- [ ] Window resize updates layout correctly
-- [ ] Very long pages scroll correctly
-- [ ] Pages without links/forms work
-- [ ] Unicode text displays correctly
-- [ ] CJK characters display correctly
-- [ ] Images render as ASCII art (if stb_image available)
-- [ ] Error handling for failed page loads
-
-## Test Websites
-
-### Simple Test Sites
-1. **http://example.com** - Basic HTML test
-2. **http://info.cern.ch** - First website ever, very simple
-3. **http://motherfuckingwebsite.com** - Minimalist design
-4. **http://textfiles.com** - Text-only content
-
-### Form Testing
-Create a local test file (test_form.html is provided):
-```bash
-python3 -m http.server 8000
-./build/tut http://localhost:8000/test_form.html
-```
-
-Test the form features:
-- Text input editing
-- Checkbox toggling
-- Dropdown selection
-- Tab navigation
-
-### Performance Testing
-1. Load a page
-2. Press 'r' to refresh (should use cache)
-3. Load the same page again (should be instant from cache)
-4. Check status bar shows "cached" messages
-
-## Known Limitations
-
-- HTTPS support depends on libcurl configuration
-- Some complex JavaScript-heavy sites won't work (static HTML only)
-- File:// URLs may not work depending on curl configuration
-- Form submission is not yet implemented
-- Cookies are not yet supported
-
-## Reporting Issues
-
-When reporting issues, please include:
-1. The URL you were trying to load
-2. The exact steps to reproduce
-3. Expected vs actual behavior
-4. Any error messages
-
-## Success Criteria
-
-The browser is working correctly if:
-1. ✓ Can load and display simple HTML pages
-2. ✓ Navigation (scroll, links) works smoothly
-3. ✓ Form interaction is responsive and intuitive
-4. ✓ Bookmarks and history persist correctly
-5. ✓ Caching improves performance noticeably
-6. ✓ No crashes or hangs during normal use
