+
+## 🎯 **Cobertura por Classe**
+
+### 🟢 **Excelente (95%+)**
+- `ArtQRCode` - 98.8%
+- `ArtQRCodeHelper` - 100%
+- `AsciiQRCode` - 100%
+- `AsciiQRCodeHelper` - 100%
+- `PngByteQRCode` - 100%
+- `PngByteQRCodeHelper` - 100%
+- `SvgQRCode` - 100%

+---
+
+## ⚠️ **Issues Identificados**
+
+### **1. Classes Sem Testes (0% Cobertura)**
+**Problema**: 8 classes principais não possuem testes unitários
+- `Base64QRCode` e Helper
+- `PdfByteQRCode` e Helper  
+- `PostscriptQRCode` e Helper
+- `SKBitmapByteQRCode` e Helper
+
+**Impacto**: Funcionalidades críticas sem cobertura de testes
+**Prioridade**: **ALTA**
+
+### **2. Classes com Baixa Cobertura**
+- `QRCodeData` - 20% (classe fundamental)
+- `SKColorExtensions` - 11.1% (extensões úteis)
+
+### **3. Warnings de Compilação**
+- 16 warnings sobre `SKPaint.FilterQuality` obsoleto
+- **Ação**: Atualizar para `SKSamplingOptions` no futuro
+
+---
+
+## 📋 **Recomendações**
+
