+# Testing Guide
+
+This project uses Jest for unit testing.
+
+## Running Tests
+
+```bash
+# Run all tests
+npm test
+
+# Run tests in watch mode
+npm run test:watch
+
+# Run tests with coverage
+npm test -- --coverage
+```
+
+## Test Structure
+
+- Tests are located alongside source files with `.test.ts` extension
+- Uses Jest with TypeScript support via `ts-jest`
+- Mocks external dependencies like `@inngest/agent-kit`
+
+## Test Coverage
+
+The test suite covers:
+- Function configuration and setup
+- Agent creation and configuration
+- Happy path execution scenarios  
+- Edge cases and error handling
+- Response format validation
+- Concurrency and performance
+- Integration scenarios
+- Real-world usage patterns
+
+## Testing Framework
+
+- **Framework**: Jest 29.7.0
+- **Environment**: Node.js
+- **TypeScript**: Supported via ts-jest
+- **Mocking**: Jest built-in mocking capabilities
