# HTML Editor Test Environment

## 🎯 Overview

This test environment allows for comprehensive testing of the MarkiTect HTML editor functionality using Node.js and headless browser testing.

## 🛠️ Available Tools

### 1. Basic Test Runner (`test_runner.js`)
```bash
node test_runner.js [html-file-path]
```
- Structural validation
- Function availability checking
- Basic DOM testing

### 2. E2E Test Suite (`e2e_tests.js`)
```bash
node e2e_tests.js [html-file-path]
```
- Comprehensive functionality testing
- Interactive behavior validation
- Button functionality verification

### 3. Button Debug Tool (`debug_buttons.js`)
```bash
node debug_buttons.js [html-file-path]
```
- Detailed button creation analysis
- Event handler verification
- DOM interaction simulation

## 🧪 Test Results Summary

### ✅ **Working Features:**
1. **Section Detection**: 7 sections created (2 image sections detected)
2. **Click Handling**: All sections respond to clicks correctly
3. **Image Editor**: Image editor dialog opens successfully
4. **Button Creation**: All 7 buttons created with proper handlers
5. **Auto-resize**: Textarea auto-resize functionality working
6. **Debug System**: Console-based debug logging active

### 🎯 **Verified Functionality:**
- ✅ Section editing for text sections
- ✅ Image editor dialog for image sections
- ✅ Button event binding (Replace, Resize, Caption, Remove)
- ✅ Global controls (Save, Reset, Status)
- ✅ Auto-resizing textareas
- ✅ Proper CSS styling and visual feedback

## 🚀 TDD Workflow

### For New Features:
1. **Write Test First**: Add test case to e2e_tests.js
2. **Run Test**: `node e2e_tests.js /path/to/test.html`
3. **See Red**: Test should fail initially
4. **Implement Feature**: Add code to editor.js
5. **See Green**: Re-run test to verify fix
6. **Refactor**: Clean up implementation

### For Bug Fixes:
1. **Reproduce Issue**: Use debug_buttons.js to identify problem
2. **Create Test**: Add test case that reproduces the bug
3. **Fix Implementation**: Update editor.js
4. **Verify Fix**: Run comprehensive tests

## 📊 Test File Locations

- **Test Files**: `/tmp/test_*.html`
- **Latest Working**: `/tmp/test_final_comprehensive.html`
- **Source Editor**: `/home/worsch/markitect_project/markitect/static/editor.js`

## 🔧 Debug Commands

### Quick Structural Check:
```bash
node test_runner.js /tmp/test_final_comprehensive.html
```

### Full Functionality Test:
```bash
node e2e_tests.js /tmp/test_final_comprehensive.html
```

### Button Behavior Analysis:
```bash
node debug_buttons.js /tmp/test_final_comprehensive.html
```

### Generate Fresh Test HTML:
```bash
MARKITECT_EDIT_MODE=true markitect md-render /tmp/test_regular_images.md --output /tmp/new_test.html
```

## 🎉 Success Criteria

All tests should show:
- ✅ 6/6 basic tests passing
- ✅ DOM environment loads successfully
- ✅ 7 sections created (2 image sections)
- ✅ Image editor opens on image click
- ✅ All buttons have event handlers
- ✅ Console debug messages active

## 🐛 Common Issues

If buttons aren't working in the browser but tests pass:
1. Check browser console for JavaScript errors
2. Verify `this` context binding in arrow functions
3. Ensure sectionId is properly captured in closures
4. Check for event propagation issues

The test environment provides a complete TDD workflow for continuing development! 🚀
