• Error Recovery - Error handling, invalid inputs, edge cases

Custom Test Utilities

The project includes custom Vitest matchers for MCP responses:

// 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:

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

For detailed testing documentation, see tests/README.md.
