## 🧪 Testing

We use [Vitest](https://vitest.dev/) as our testing framework with comprehensive test coverage.

### Running Tests

```bash
# Run all unit tests
npm test

# Run tests in watch mode (re-runs on file changes)
npm run test:watch

# Run tests with coverage report
npm run test:coverage

# Run E2E tests (requires network access)
npm run test:e2e

# Run E2E tests in watch mode
npm run test:e2e:watch

# Open interactive test UI
npm run test:ui
```

### MCP Inspector

Test your MCP tools interactively using the official [MCP Inspector](https://github.com/modelcontextprotocol/inspector):

```bash
npm run test:inspector
```

This opens a browser-based UI where you can:
- Browse all available tools and prompts
- Test tool execution with custom parameters
- View tool responses and debug issues
- Validate your MCP server implementation

### Running Tests

```bash
# Run all tests
npm test

# Run unit tests only
npm run test:unit

# Run integration tests
npm run test:integration

# Run E2E tests (requires network access)
npm run test:e2e

# Run tests with coverage report
npm run test:coverage

# Run tests in watch mode (development)
npm run test:watch
```

### Test Structure

| Type | Location | Description |
|------|----------|-------------|
| **Unit** | `src/**/*.test.ts` | Test individual functions/modules |
| **Integration** | `tests/integration/` | Test multiple components together |
| **E2E** | `tests/e2e/` | Test full MCP server flow |

### E2E Tests

End-to-end tests verify the complete tool execution flow:

- **EVM Tools** - Block, balance, token operations across chains
- **DeFi Tools** - Protocol TVL, yields, stablecoins via DefiLlama
- **Market Data** - CoinGecko, Fear & Greed index
- **Multichain** - Same operations across different networks
- **Error Recovery** - Error handling, invalid inputs, edge cases

### Custom Test Utilities

The project includes custom Vitest matchers for MCP responses:

```typescript
// In your test file
import "../utils/assertions"

expect(result).toBeSuccessfulToolResponse()
expect(result).toHaveJsonProperty("balance")
expect(result).toContainValidAddress()
expect(result).toContainToolError(/invalid/i)
```

### Test Fixtures

Reusable test data in `tests/utils/fixtures.ts`:

```typescript
import {
  ETH_MAINNET_ADDRESSES,
  MOCK_TOKEN_DATA,
  generateRandomAddress
} from "../utils/fixtures"
```

For detailed testing documentation, see [tests/README.md](tests/README.md).
