For comprehensive guidelines, refer to Node.js Integration Tests Best Practices. While it primarily focuses on Node.js, its principles are universal and applicable across any language or framework.

Key principles include:

1. Test Real Integrations: Avoid excessive mocking and stubbing. Test actual databases, APIs, or message queues to ensure interactions work as expected.
2. Keep Tests Deterministic: Ensure tests produce the same results regardless of external factors or execution order.
3. Write Tests for Critical Paths: Focus on testing workflows and features that are core to the application's business value.
4. Fast Feedback: Strive for efficient test execution while balancing thoroughness, using tools like parallelization when necessary.
