AI Integration Test Generator

Unit tests verify individual functions in isolation with mocked dependencies. Integration tests verify that multiple components work correctly together — testing real database queries, actual API endpoints, and genuine service interactions. Our generator creates tests that exercise the full stack or significant portions of it, catching issues that unit tests cannot detect.

Four strategies are available: Factory functions create test data programmatically with sensible defaults and easy customization. Fixtures use predefined data files loaded before tests. Inline data defines test data directly in each test for maximum clarity. Seed files use SQL or JSON data loaded into the test database. Choose based on your existing test infrastructure.

Each test suite includes proper setup and teardown to prevent test pollution. For database tests, it wraps each test in a transaction that rolls back after completion, or truncates relevant tables between tests. For API tests, it creates fresh test users and tokens for each suite. This ensures tests are independent and can run in any order.

Yes, select the Full workflow scope and describe your multi-step flow. The generator creates sequential tests that build on each other — for example, registering a user, then logging in with those credentials, then accessing a protected resource. Each step asserts the expected state and passes data like tokens or IDs to subsequent steps.

For external services, the generator creates tests using interceptors or mocked HTTP clients that simulate external API responses. This lets you test your integration logic without depending on external service availability. It covers success responses, error responses, timeouts, and rate limiting scenarios to ensure your integration handles all cases gracefully.
