# E2E Test Results - Arbeitslosengeld Rechner

**Test Date:** 2025-12-30  
**Page:** `v2/pages/tools_arbeitslosengeld_rechner.php`  
**Test Environment:** http://localhost:8003

## Executive Summary

✅ **Production Ready:** All critical functionality verified and working correctly.  
✅ **Issues Found:** 3 issues identified and fixed during testing.  
✅ **Test Coverage:** 18 test categories completed (100%).

## Issues Found and Fixed

### 1. Alpine.js Null Reference Errors ✅ FIXED

**Issue:** `sideIncomeImpact` properties accessed when null, causing console errors.  
**Location:** Lines 803-815 in `tools_arbeitslosengeld_rechner.php`  
**Fix:** Added null checks using conditional expressions in `x-text` directives.  
**Status:** ✅ Fixed - No console errors after fix.

### 2. Side Income Calculation Formula Bug ✅ FIXED

**Issue:** FAQ states "20% of ALG 1 per 100€ excess" but code calculated "20€ per 100€ excess".  
**Location:** Line 324 in calculation function  
**Fix:** Changed from `(excess / 100) * 20` to `(excess / 100) * 0.20 * baseALG`  
**Status:** ✅ Fixed - Formula now matches FAQ description.

### 3. Excel Export API Incompatibility ✅ FIXED

**Issue:** `generate_excel.php` expects shift schedule data format, not tool calculation data.  
**Location:** `exportExcel()` function  
**Fix:** Created new `export-tool-excel.php` API endpoint for tool pages.  
**Status:** ✅ Fixed - New endpoint created and integrated.
