# 🔧 Input Component Tests Refactoring

**File**: `packages/leptos/input/src/implementation_tests.rs`  
**Current Size**: 867 lines  
**Target**: Split into 6 modules of ~150 lines each  
**Priority**: 🔴 **CRITICAL**

## 🚨 Current Issues

### **File Size Problems**
- **867 lines** in a single file
- **Mixed test categories** in one file
- **Hard to navigate** and maintain
- **Poor LLM comprehension** due to size

### **Test Organization Issues**
- Basic functionality tests mixed with complex integration tests
- Performance tests scattered throughout
- Error handling tests not grouped
- Accessibility tests not separated

## 🎯 Refactoring Strategy

### **New Module Structure**
