+
+## 🧪 Testes Unitários
+
+**Execução:**
+```bash
+bun test                    # Todos os testes
+bun test --watch            # Watch mode
+bun test unit/              # Apenas testes unitários
+bun test <arquivo>          # Teste específico
+```
+
+**Cobertura:**
+- `errors.test.ts` - Sistema de erros e classificação (30+ testes)
+- `oauth.test.ts` - PKCE, OAuth helpers, constants (20+ testes)
+- `request-queue.test.ts` - Throttling e rate limiting (15+ testes)
+- `token-manager.test.ts` - Gerenciamento de tokens (10+ testes)
+- `file-lock.test.ts` - File locking mechanism (20+ testes)
+- `auth-integration.test.ts` - Integração de componentes (15+ testes)
+
+**Total:** 100+ testes automatizados
+
+## 🔬 Testes de Integração (Manuais)
+
+### Debug (End-to-End)
+
+Testa o sistema completo com a API Qwen real.
+
+**Pré-requisitos:**
+- Login realizado (`opencode auth login`)
+- Credenciais válidas
+
+**Execução:**
+```bash
+bun run test:integration
+# OU
+bun run tests/integration/debug.ts full
+```
+
+**Testes incluídos:**
+- PKCE generation
+- Base URL resolution
+- Credentials persistence
+- Token expiry check
+- Token refresh
+- Retry mechanism
+- Throttling
+- TokenManager
+- 401 recovery
+- **Real Chat API call** (requer login)
+
+### Race Condition
+
+Testa concorrência entre múltiplos processos do plugin.
+
+**Execução:**
+```bash
+bun run test:race
+# OU
+bun run tests/integration/race-condition.ts
+```
+
+**O que testa:**
+- Dois processos tentando refresh simultâneo
+- File locking previne race conditions
+- Recuperação de locks stale
+
+## 💪 Stress Tests (Robust)
+
+Testes de alta concorrência e cenários extremos.
+
+**Execução:**
+```bash
+bun run test:robust
+# OU
+bun run tests/robust/runner.ts
+```
+
+**Testes incluídos:**
+1. **Race Condition (2 processos)** - Concorrência básica
+2. **Stress Concurrency (10 processos)** - Alta concorrência
+3. **Stale Lock Recovery** - Recuperação de locks abandonados
+4. **Corrupted File Recovery** - Arquivo de credenciais corrompido
+
+**Duração:** ~30-60 segundos
+
+## 📊 Scripts package.json
+
+```json
+{
+  "scripts": {
+    "test": "bun test",
+    "test:watch": "bun test --watch",
+    "test:integration": "bun run tests/integration/debug.ts full",
+    "test:race": "bun run tests/integration/race-condition.ts",
+    "test:robust": "bun run tests/robust/runner.ts"
+  }
+}
+```
+
+## 🎯 Quando usar cada tipo
+
+| Tipo | Quando usar | Requer login? | Automatizado? |
+|------|-------------|---------------|---------------|
+| **Unitários** | CI/CD, desenvolvimento diário | ❌ Não | ✅ Sim |
+| **Integration (debug)** | Validação manual, troubleshooting | ✅ Sim | ❌ Não |
+| **Race Condition** | Desenvolvimento de features novas | ❌ Não | ❌ Não |
+| **Robust** | Validação pré-release | ❌ Não | ❌ Não |
+
+## 🔍 Debug de Testes
+
+**Habilitar logs detalhados:**
+```bash
+OPENCODE_QWEN_DEBUG=1 bun test
+```
+
+**Verbose mode no debug.ts:**
+```bash
+OPENCODE_QWEN_DEBUG=1 bun run tests/integration/debug.ts full
+```
+
+## 📝 Adicionando Novos Testes
+
+1. **Testes unitários:** Crie `tests/unit/<nome>.test.ts`
+2. **Testes de integração:** Crie `tests/integration/<nome>.ts`
+3. **Use `bun:test`:**
+   ```typescript
+   import { describe, it, expect, mock } from 'bun:test';
+   ```
+
+## ⚠️ Notas Importantes
+
+1. **Testes unitários** não modificam credenciais reais
+2. **Testes de integração** podem modificar credenciais (usam cópias de teste)
+3. **Stress tests** criam locks temporários e os limpam automaticamente
+4. **Sempre rode** `bun test` antes de commitar
