feat: Implement pluggable multi-provider sandbox architecture (#12820)

## Summary

Implement a flexible sandbox provider system supporting both
self-managed (Docker) and SaaS (Aliyun Code Interpreter) backends for
secure code execution in agent workflows.

**Key Changes:**
- ✅ Aliyun Code Interpreter provider using official
`agentrun-sdk>=0.0.16`
- ✅ Self-managed provider with gVisor (runsc) security
- ✅ Arguments parameter support for dynamic code execution
- ✅ Database-only configuration (removed fallback logic)
- ✅ Configuration scripts for quick setup

Issue #12479

## Features

### 🔌 Provider Abstraction Layer

**1. Self-Managed Provider** (`agent/sandbox/providers/self_managed.py`)
- Wraps existing executor_manager HTTP API
- gVisor (runsc) for secure container isolation
- Configurable pool size, timeout, retry logic
- Languages: Python, Node.js, JavaScript
- ⚠️ **Requires**: gVisor installation, Docker, base images

**2. Aliyun Code Interpreter**
(`agent/sandbox/providers/aliyun_codeinterpreter.py`)
- SaaS integration using official agentrun-sdk
- Serverless microVM execution with auto-authentication
- Hard timeout: 30 seconds max
- Credentials: `AGENTRUN_ACCESS_KEY_ID`, `AGENTRUN_ACCESS_KEY_SECRET`,
`AGENTRUN_ACCOUNT_ID`, `AGENTRUN_REGION`
- Automatically wraps code to call `main()` function

**3. E2B Provider** (`agent/sandbox/providers/e2b.py`)
- Placeholder for future integration

### ⚙️ Configuration System

- `conf/system_settings.json`: Default provider =
`aliyun_codeinterpreter`
- `agent/sandbox/client.py`: Enforces database-only configuration
- Admin UI: `/admin/sandbox-settings`
- Configuration validation via `validate_config()` method
- Health checks for all providers

### 🎯 Key Capabilities

**Arguments Parameter Support:**
All providers support passing arguments to `main()` function:
```python
# User code
def main(name: str, count: int) -> dict:
    return {"message": f"Hello {name}!" * count}

# Executed with: arguments={"name": "World", "count": 3}
# Result: {"message": "Hello World!Hello World!Hello World!"}
```

**Self-Describing Providers:**
Each provider implements `get_config_schema()` returning form
configuration for Admin UI

**Error Handling:**
Structured `ExecutionResult` with stdout, stderr, exit_code,
execution_time

## Configuration Scripts

Two scripts for quick Aliyun sandbox setup:

**Shell Script (requires jq):**
```bash
source scripts/configure_aliyun_sandbox.sh
```

**Python Script (interactive):**
```bash
python3 scripts/configure_aliyun_sandbox.py
```

## Testing

```bash
# Unit tests
uv run pytest agent/sandbox/tests/test_providers.py -v

# Aliyun provider tests
uv run pytest agent/sandbox/tests/test_aliyun_codeinterpreter.py -v

# Integration tests (requires credentials)
uv run pytest agent/sandbox/tests/test_aliyun_codeinterpreter_integration.py -v

# Quick SDK validation
python3 agent/sandbox/tests/verify_sdk.py
```

**Test Coverage:**
- 30 unit tests for provider abstraction
- Provider-specific tests for Aliyun
- Integration tests with real API
- Security tests for executor_manager

## Documentation

- `docs/develop/sandbox_spec.md` - Complete architecture specification
- `agent/sandbox/tests/MIGRATION_GUIDE.md` - Migration from legacy
sandbox
- `agent/sandbox/tests/QUICKSTART.md` - Quick start guide
- `agent/sandbox/tests/README.md` - Testing documentation

## Breaking Changes

⚠️ **Migration Required:**

1. **Directory Move**: `sandbox/` → `agent/sandbox/`
   - Update imports: `from sandbox.` → `from agent.sandbox.`

2. **Mandatory Configuration**: 
   - SystemSettings must have `sandbox.provider_type` configured
   - Removed fallback default values
- Configuration must exist in database (from
`conf/system_settings.json`)

3. **Aliyun Credentials**:
   - Requires `AGENTRUN_*` environment variables (not `ALIYUN_*`)
   - `AGENTRUN_ACCOUNT_ID` is now required (Aliyun primary account ID)

4. **Self-Managed Provider**:
   - gVisor (runsc) must be installed for security
   - Install: `go install gvisor.dev/gvisor/runsc@latest`

## Database Schema Changes

```python
# SystemSettings.value: CharField → TextField
api/db/db_models.py: Changed for unlimited config length

# SystemSettingsService.get_by_name(): Fixed query precision
api/db/services/system_settings_service.py: startswith → exact match
```

## Files Changed

## Architecture

```
Admin UI → Admin API → SandboxMgr → ProviderManager → [SelfManaged|Aliyun|E2B]
                                      ↓
                                  SystemSettings
```

## Usage

### 1. Configure Provider

**Via Admin UI:**
1. Navigate to `/admin/sandbox-settings`
2. Select provider (Aliyun Code Interpreter / Self-Managed)
3. Fill in configuration
4. Click "Test Connection" to verify
5. Click "Save" to apply

**Via Configuration Scripts:**
```bash
# Aliyun provider
export AGENTRUN_ACCESS_KEY_ID="xxx"
export AGENTRUN_ACCESS_KEY_SECRET="yyy"
export AGENTRUN_ACCOUNT_ID="zzz"
export AGENTRUN_REGION="cn-shanghai"
source scripts/configure_aliyun_sandbox.sh
```

### 2. Restart Service

```bash
cd docker
docker compose restart ragflow-server
```

### 3. Execute Code in Agent

```python
from agent.sandbox.client import execute_code

result = execute_code(
    code='def main(name: str) -> dict: return {"message": f"Hello {name}!"}',
    language="python",
    timeout=30,
    arguments={"name": "World"}
)

print(result.stdout)  # {"message": "Hello World!"}
```

## Troubleshooting

### "Container pool is busy" (Self-Managed)
- **Cause**: Pool exhausted (default: 1 container in `.env`)
- **Fix**: Increase `SANDBOX_EXECUTOR_MANAGER_POOL_SIZE` to 5+

### "Sandbox provider type not configured"
- **Cause**: Database missing configuration
- **Fix**: Run config script or set via Admin UI

### "gVisor not found"
- **Cause**: runsc not installed
- **Fix**: `go install gvisor.dev/gvisor/runsc@latest && sudo cp
~/go/bin/runsc /usr/local/bin/`

### Aliyun authentication errors
- **Cause**: Wrong environment variable names
- **Fix**: Use `AGENTRUN_*` prefix (not `ALIYUN_*`)

+# Aliyun Code Interpreter Provider - 使用官方 SDK
+
+## 重要变更
+
+### 官方资源
+- **Code Interpreter API**: https://help.aliyun.com/zh/functioncompute/fc/sandbox-sandbox-code-interepreter
+- **官方 SDK**: https://github.com/Serverless-Devs/agentrun-sdk-python
+- **SDK 文档**: https://docs.agent.run
+
+## 使用官方 SDK 的优势
+
+从手动 HTTP 请求迁移到官方 SDK (`agentrun-sdk`) 有以下优势：
+
+### 1. **自动签名认证**
+- SDK 自动处理 Aliyun API 签名（无需手动实现 `Authorization` 头）
+- 支持多种认证方式：AccessKey、STS Token
+- 自动读取环境变量
+
+### 2. **简化的 API**
+```python
+# 旧实现（手动 HTTP 请求）
+response = requests.post(
+    f"{DATA_ENDPOINT}/sandboxes/{sandbox_id}/execute",
+    headers={"X-Acs-Parent-Id": account_id},
+    json={"code": code, "language": "python"}
+)
+
+# 新实现（使用 SDK）
+sandbox = CodeInterpreterSandbox(template_name="python-sandbox", config=config)
+result = sandbox.context.execute(code="print('hello')")
+```
+
+### 3. **更好的错误处理**
+- 结构化的异常类型 (`ServerError`)
+- 自动重试机制
+- 详细的错误信息
+
+## 主要变更
+
+### 1. 文件重命名
+
+| 旧文件名 | 新文件名 | 说明 |
+|---------|---------|------|
+| `aliyun_opensandbox.py` | `aliyun_codeinterpreter.py` | 提供商实现 |
+| `test_aliyun_provider.py` | `test_aliyun_codeinterpreter.py` | 单元测试 |
+| `test_aliyun_integration.py` | `test_aliyun_codeinterpreter_integration.py` | 集成测试 |
+
+### 2. 配置字段变更
+
+#### 旧配置（OpenSandbox）
+```json
+{
+  "access_key_id": "LTAI5t...",
+  "access_key_secret": "...",
+  "region": "cn-hangzhou",
+  "workspace_id": "ws-xxxxx"
+}
+```
+
+#### 新配置（Code Interpreter）
+```json
+{
+  "access_key_id": "LTAI5t...",
+  "access_key_secret": "...",
+  "account_id": "1234567890...",  // 新增：阿里云主账号ID（必需）
+  "region": "cn-hangzhou",
+  "template_name": "python-sandbox",  // 新增：沙箱模板名称
+  "timeout": 30  // 最大 30 秒（硬限制）
+}
+```
+
+### 3. 关键差异
+
+| 特性 | OpenSandbox | Code Interpreter |
+|------|-------------|-----------------|
+| **API 端点** | `opensandbox.{region}.aliyuncs.com` | `agentrun.{region}.aliyuncs.com` (控制面) |
+| **API 版本** | `2024-01-01` | `2025-09-10` |
+| **认证** | 需要 AccessKey | 需要 AccessKey + 主账号ID |
+| **请求头** | 标准签名 | 需要 `X-Acs-Parent-Id` 头 |
+| **超时限制** | 可配置 | **最大 30 秒**（硬限制） |
+| **上下文** | 不支持 | 支持上下文（Jupyter kernel） |
+
+### 4. API 调用方式变更
+
+#### 旧实现（假设的 OpenSandbox）
+```python
+# 单一端点
+API_ENDPOINT = "https://opensandbox.cn-hangzhou.aliyuncs.com"
+
+# 简单的请求/响应
+response = requests.post(
+    f"{API_ENDPOINT}/execute",
+    json={"code": "print('hello')", "language": "python"}
+)
+```
+
+#### 新实现（Code Interpreter）
+```python
+# 控制面 API - 管理沙箱生命周期
+CONTROL_ENDPOINT = "https://agentrun.cn-hangzhou.aliyuncs.com/2025-09-10"
+
+# 数据面 API - 执行代码
+DATA_ENDPOINT = "https://{account_id}.agentrun-data.cn-hangzhou.aliyuncs.com"
+
+# 创建沙箱（控制面）
+response = requests.post(
+    f"{CONTROL_ENDPOINT}/sandboxes",
+    headers={"X-Acs-Parent-Id": account_id},
+    json={"templateName": "python-sandbox"}
+)
+
+# 执行代码（数据面）
+response = requests.post(
+    f"{DATA_ENDPOINT}/sandboxes/{sandbox_id}/execute",
+    headers={"X-Acs-Parent-Id": account_id},
+    json={"code": "print('hello')", "language": "python", "timeout": 30}
+)
+```
+
+### 5. 迁移步骤
+
+#### 步骤 1: 更新配置
+
+如果您之前使用的是 `aliyun_opensandbox`：
+
+**旧配置**:
+```json
+{
+  "name": "sandbox.provider_type",
+  "value": "aliyun_opensandbox"
+}
+```
+
+**新配置**:
+```json
+{
+  "name": "sandbox.provider_type",
+  "value": "aliyun_codeinterpreter"
+}
+```
+
+#### 步骤 2: 添加必需的 account_id
+
+在 Aliyun 控制台右上角点击头像，获取主账号 ID：
+1. 登录 [阿里云控制台](https://ram.console.aliyun.com/manage/ak)
+2. 点击右上角头像
+3. 复制主账号 ID（16 位数字）
+
+#### 步骤 3: 更新环境变量
+
+```bash
+# 新增必需的环境变量
+export ALIYUN_ACCOUNT_ID="1234567890123456"
+
+# 其他环境变量保持不变
+export ALIYUN_ACCESS_KEY_ID="LTAI5t..."
+export ALIYUN_ACCESS_KEY_SECRET="..."
+export ALIYUN_REGION="cn-hangzhou"
+```
+
+#### 步骤 4: 运行测试
+
+```bash
+# 单元测试（不需要真实凭据）
+pytest agent/sandbox/tests/test_aliyun_codeinterpreter.py -v
+
+# 集成测试（需要真实凭据）
+pytest agent/sandbox/tests/test_aliyun_codeinterpreter_integration.py -v -m integration
+```
+
+## 文件变更清单
+
+### ✅ 已完成
+
+- [x] 创建 `aliyun_codeinterpreter.py` - 新的提供商实现
+- [x] 更新 `sandbox_spec.md` - 规范文档
+- [x] 更新 `admin/services.py` - 服务管理器
+- [x] 更新 `providers/__init__.py` - 包导出
+- [x] 创建 `test_aliyun_codeinterpreter.py` - 单元测试
+- [x] 创建 `test_aliyun_codeinterpreter_integration.py` - 集成测试
+
+### 📝 可选清理
+
+如果您想删除旧的 OpenSandbox 实现：
+
+```bash
+# 删除旧文件（可选）
+rm agent/sandbox/providers/aliyun_opensandbox.py
+rm agent/sandbox/tests/test_aliyun_provider.py
+rm agent/sandbox/tests/test_aliyun_integration.py
+```
+
+**注意**: 保留旧文件不会影响新功能，只是代码冗余。
+
+## API 参考
+
+### 控制面 API（沙箱管理）
+
+| 端点 | 方法 | 说明 |
+|------|------|------|
+| `/sandboxes` | POST | 创建沙箱实例 |
+| `/sandboxes/{id}/stop` | POST | 停止实例 |
+| `/sandboxes/{id}` | DELETE | 删除实例 |
+| `/templates` | GET | 列出模板 |
+
+### 数据面 API（代码执行）
+
+| 端点 | 方法 | 说明 |
+|------|------|------|
+| `/sandboxes/{id}/execute` | POST | 执行代码（简化版） |
+| `/sandboxes/{id}/contexts` | POST | 创建上下文 |
+| `/sandboxes/{id}/contexts/{ctx_id}/execute` | POST | 在上下文中执行 |
+| `/sandboxes/{id}/health` | GET | 健康检查 |
+| `/sandboxes/{id}/files` | GET/POST | 文件读写 |
+| `/sandboxes/{id}/processes/cmd` | POST | 执行 Shell 命令 |
+
+## 常见问题
+
+### Q: 为什么要添加 account_id？
+
+**A**: Code Interpreter API 需要在请求头中提供 `X-Acs-Parent-Id`（阿里云主账号ID）进行身份验证。这是 Aliyun Code Interpreter API 的必需参数。
+
+### Q: 30 秒超时限制可以绕过吗？
+
+**A**: 不可以。这是 Aliyun Code Interpreter 的**硬限制**，无法通过配置或请求参数绕过。如果代码执行时间超过 30 秒，请考虑：
+1. 优化代码逻辑
+2. 分批处理数据
+3. 使用上下文保持状态
+
+### Q: 旧的 OpenSandbox 配置还能用吗？
+
+**A**: 不能。OpenSandbox 和 Code Interpreter 是两个不同的服务，API 不兼容。必须迁移到新的配置格式。
+
+### Q: 如何获取阿里云主账号 ID？
+
+**A**:
+1. 登录阿里云控制台
+2. 点击右上角的头像
+3. 在弹出的信息中可以看到"主账号ID"
+
+### Q: 迁移后会影响现有功能吗？
+
+**A**:
+- **自我管理提供商（self_managed）**: 不受影响
+- **E2B 提供商**: 不受影响
+- **Aliyun 提供商**: 需要更新配置并重新测试

+# Aliyun OpenSandbox Provider - 快速测试指南
+
+## 测试说明
+
+### 1. 单元测试（不需要真实凭据）
+
+单元测试使用 mock，**不需要**真实的 Aliyun 凭据，可以随时运行。
+
+```bash
+# 运行 Aliyun 提供商的单元测试
+pytest agent/sandbox/tests/test_aliyun_provider.py -v
+
+# 预期输出：
+# test_aliyun_provider.py::TestAliyunOpenSandboxProvider::test_provider_initialization PASSED
+# test_aliyun_provider.py::TestAliyunOpenSandboxProvider::test_initialize_success PASSED
+# ...
+# ========================= 48 passed in 2.34s ==========================
+```
+
+### 2. 集成测试（需要真实凭据）
+
+集成测试会调用真实的 Aliyun API，需要配置凭据。
+
+#### 步骤 1: 配置环境变量
+
+```bash
+export ALIYUN_ACCESS_KEY_ID="LTAI5t..."  # 替换为真实的 Access Key ID

+```
+
+## 常见问题
+
+### Q: 没有凭据怎么办？
+
+**A:** 运行单元测试即可，不需要真实凭据：
+```bash
+pytest agent/sandbox/tests/test_aliyun_provider.py -v
+```
+
+### Q: 如何跳过集成测试？
+
+**A:** 使用 pytest 标记跳过：
+```bash
+# 只运行单元测试，跳过集成测试
+pytest agent/sandbox/tests/ -v -m "not integration"
+```
+
+### Q: 集成测试失败怎么办？
+
+**A:** 检查以下几点：
+
+1. **凭据是否正确**
+   ```bash
+   echo $ALIYUN_ACCESS_KEY_ID
+   echo $ALIYUN_ACCESS_KEY_SECRET
+   ```
+
+2. **网络连接是否正常**
+   ```bash
+   curl -I https://opensandbox.cn-hangzhou.aliyuncs.com
+   ```
+
+3. **是否有 OpenSandbox 服务权限**
+   - 登录阿里云控制台
+   - 检查是否已开通 OpenSandbox 服务
+   - 检查 AccessKey 权限
+
+4. **查看详细错误信息**
+   ```bash
+   pytest agent/sandbox/tests/test_aliyun_integration.py -v -s
+   ```
+
+### Q: 测试超时怎么办？
+
+**A:** 增加超时时间或检查网络：
+```bash
+# 使用更长的超时
+pytest agent/sandbox/tests/test_aliyun_integration.py -v --timeout=60
+```
+
+## 测试命令速查表
+
+| 命令 | 说明 | 需要凭据 |
+|------|------|---------|
+| `pytest agent/sandbox/tests/test_aliyun_provider.py -v` | 单元测试 | ❌ |
+| `pytest agent/sandbox/tests/test_aliyun_integration.py -v` | 集成测试 | ✅ |
+| `pytest agent/sandbox/tests/ -v -m "not integration"` | 仅单元测试 | ❌ |
+| `pytest agent/sandbox/tests/ -v -m integration` | 仅集成测试 | ✅ |
+| `pytest agent/sandbox/tests/ -v` | 所有测试 | 部分需要 |
+
+## 获取 Aliyun 凭据
+
+1. 访问 [阿里云控制台](https://ram.console.aliyun.com/manage/ak)

+# Sandbox Provider Tests
+
+This directory contains tests for the RAGFlow sandbox provider system.
+
+## Test Structure
+
+```
+tests/
+├── pytest.ini                           # Pytest configuration
+├── test_providers.py                    # Unit tests for all providers (mocked)
+├── test_aliyun_provider.py              # Unit tests for Aliyun provider (mocked)
+├── test_aliyun_integration.py           # Integration tests for Aliyun (real API)
+└── sandbox_security_tests_full.py      # Security tests for self-managed provider
+```
+
+## Test Types
+
+### 1. Unit Tests (No Credentials Required)
+
+Unit tests use mocks and don't require any external services or credentials.
+
+**Files:**
+- `test_providers.py` - Tests for base provider interface and manager
+- `test_aliyun_provider.py` - Tests for Aliyun provider with mocked API calls
+
+**Run unit tests:**
+```bash
+# Run all unit tests
+pytest agent/sandbox/tests/test_providers.py -v
+pytest agent/sandbox/tests/test_aliyun_provider.py -v
+
+# Run specific test
+pytest agent/sandbox/tests/test_aliyun_provider.py::TestAliyunOpenSandboxProvider::test_initialize_success -v
+
+# Run all unit tests (skip integration)
+pytest agent/sandbox/tests/ -v -m "not integration"
+```
+
+### 2. Integration Tests (Real Credentials Required)
+
+Integration tests make real API calls to Aliyun OpenSandbox service.
+
+**Files:**
+- `test_aliyun_integration.py` - Tests with real Aliyun API calls
+
+**Setup environment variables:**
+```bash
+export ALIYUN_ACCESS_KEY_ID="LTAI5t..."
+export ALIYUN_ACCESS_KEY_SECRET="..."
+export ALIYUN_REGION="cn-hangzhou"  # Optional, defaults to cn-hangzhou
+export ALIYUN_WORKSPACE_ID="ws-..."  # Optional
+```
+
+**Run integration tests:**
+```bash
+# Run only integration tests
+pytest agent/sandbox/tests/test_aliyun_integration.py -v -m integration
+
+# Run all tests including integration
+pytest agent/sandbox/tests/ -v
+
+# Run specific integration test
+pytest agent/sandbox/tests/test_aliyun_integration.py::TestAliyunOpenSandboxIntegration::test_health_check -v
+```
+
+### 3. Security Tests
+
+Security tests validate the security features of the self-managed sandbox provider.
+
+**Files:**
+- `sandbox_security_tests_full.py` - Comprehensive security tests
+
+**Run security tests:**
+```bash
+# Run all security tests
+pytest agent/sandbox/tests/sandbox_security_tests_full.py -v
+
+# Run specific security test
+pytest agent/sandbox/tests/sandbox_security_tests_full.py -k "test_dangerous_imports" -v
+```
+
+## Test Commands
+
+### Quick Test Commands
+
+```bash
+# Run all sandbox tests (unit only, fast)
+pytest agent/sandbox/tests/ -v -m "not integration" --tb=short
+
+# Run tests with coverage
+pytest agent/sandbox/tests/ -v --cov=agent.sandbox --cov-report=term-missing -m "not integration"
+
+# Run tests and stop on first failure
+pytest agent/sandbox/tests/ -v -x -m "not integration"
+
+# Run tests in parallel (requires pytest-xdist)
+pytest agent/sandbox/tests/ -v -n auto -m "not integration"
+```
+
+### Aliyun Provider Testing
+
+```bash
+# 1. Run unit tests (no credentials needed)
+pytest agent/sandbox/tests/test_aliyun_provider.py -v
+
+# 2. Set up credentials for integration tests
+export ALIYUN_ACCESS_KEY_ID="your-key-id"
+export ALIYUN_ACCESS_KEY_SECRET="your-secret"
+export ALIYUN_REGION="cn-hangzhou"
+
+# 3. Run integration tests (makes real API calls)
+pytest agent/sandbox/tests/test_aliyun_integration.py -v
+
+# 4. Test specific scenarios
+pytest agent/sandbox/tests/test_aliyun_integration.py::TestAliyunOpenSandboxIntegration::test_execute_python_code -v
+pytest agent/sandbox/tests/test_aliyun_integration.py::TestAliyunRealWorldScenarios -v
+```
+
+## Understanding Test Results
+
+### Unit Test Output
+
+```
+agent/sandbox/tests/test_aliyun_provider.py::TestAliyunOpenSandboxProvider::test_initialize_success PASSED
+agent/sandbox/tests/test_aliyun_provider.py::TestAliyunOpenSandboxProvider::test_create_instance_python PASSED
+...
+========================== 48 passed in 2.34s ===========================
+```
+
+### Integration Test Output
+
+```
+agent/sandbox/tests/test_aliyun_integration.py::TestAliyunOpenSandboxIntegration::test_health_check PASSED
+agent/sandbox/tests/test_aliyun_integration.py::TestAliyunOpenSandboxIntegration::test_create_python_instance PASSED
+agent/sandbox/tests/test_aliyun_integration.py::TestAliyunOpenSandboxIntegration::test_execute_python_code PASSED
+...
+========================== 10 passed in 15.67s ===========================
+```
+
+**Note:** Integration tests will be skipped if credentials are not set:
+```
+agent/sandbox/tests/test_aliyun_integration.py::TestAliyunOpenSandboxIntegration::test_health_check SKIPPED
+...
+========================== 48 skipped, 10 passed in 0.12s ===========================
+```
+
+## Troubleshooting
+
+### Integration Tests Fail
+
+1. **Check credentials:**
+   ```bash
+   echo $ALIYUN_ACCESS_KEY_ID
+   echo $ALIYUN_ACCESS_KEY_SECRET
+   ```
+
+2. **Check network connectivity:**
+   ```bash
+   curl -I https://opensandbox.cn-hangzhou.aliyuncs.com
+   ```
+
+3. **Verify permissions:**
+   - Make sure your Aliyun account has OpenSandbox service enabled
+   - Check that your AccessKey has the required permissions
+
+4. **Check region:**
+   - Verify the region is correct for your account
+   - Try different regions: cn-hangzhou, cn-beijing, cn-shanghai, etc.
+
+### Tests Timeout
+
+If tests timeout, increase the timeout in the test configuration or run with a longer timeout:
+```bash
+pytest agent/sandbox/tests/test_aliyun_integration.py -v --timeout=60
+```
+
+### Mock Tests Fail
+
+If unit tests fail, it's likely a code issue, not a credentials issue:
+1. Check the test error message
+2. Review the code changes
+3. Run with verbose output: `pytest -vv`
+
+## Contributing
+
+When adding new providers:
+
+1. **Create unit tests** in `test_{provider}_provider.py` with mocks
+2. **Create integration tests** in `test_{provider}_integration.py` with real API calls
+3. **Add markers** to distinguish test types
+4. **Update this README** with provider-specific testing instructions
+
+Example:
+```python
+@pytest.mark.integration
+def test_new_provider_real_api():
+    """Test with real API calls."""
+    # Your test here
+```
+
+## Continuous Integration
+
+In CI/CD pipelines:
+
+```yaml
+# Run unit tests only (fast, no credentials)
+pytest agent/sandbox/tests/ -v -m "not integration"
+
+# Run integration tests if credentials available
+if [ -n "$ALIYUN_ACCESS_KEY_ID" ]; then
+    pytest agent/sandbox/tests/test_aliyun_integration.py -v -m integration
+fi
+```
