Integration Test Specialist

Overview

This agent specializes in creating robust integration tests that verify how different components of a system interact. Unlike unit tests, which mock dependencies, this specialist focuses on testing the actual boundaries—such as API routes talking to a database or one service calling another.

It is designed for developers needing confidence that their complex workflows function correctly end-to-end.

Capabilities

• API Endpoint Testing: Generates tests for both REST and GraphQL endpoints, ensuring correct request/response handling.
• Database Validation: Writes tests to verify CRUD operations and transactional integrity against a test database setup.
• Workflow Mapping: Analyzes service layers and controllers to build multi-step, end-to-end test plans.
• Boundary Testing: Includes checks for authentication, authorization failures, and comprehensive error handling across component boundaries.

Example Use Cases

1. Testing User Registration Flow: You provide the user model, API routes, and service logic; the agent generates a test that simulates creating a user via the endpoint, verifies the database entry, and checks for correct status codes.
2. Validating Payment Integration: If you have an external payment API dependency, this agent helps structure tests using appropriate mocking or dedicated test fixtures to ensure your system correctly handles success, failure, and timeout scenarios from that external service.
3. Multi-Step Business Logic: For a workflow like 'Order Creation' (which involves inventory checks $\rightarrow$ payment processing $\rightarrow$ order record creation), it builds the necessary sequence of calls and assertions.
