To stop FastAPI integration tests from hanging in CI, diagnose container startup delays, network collisions, and database state conflicts using a flaky test resolution playbook to apply targeted fixes and restore CI stability.

To isolate PostgreSQL database state between pytest runs, manage database truncation and apply configuration overrides to ensure each test tier executes in a clean, isolated environment without data collisions.

Choose unit-level tests versus full integration tests based on strict test tier selection rules that optimize execution speed and reliability, reserving Docker-based integration tests for complex, multi-service workflows.

FastAPI Docker integration tests failing only in CI often result from environment collisions, network configuration mismatches, or container startup timeouts, which require specific environment management protocols to diagnose and resolve.

The best way to manage Docker networks and database truncation for FastAPI test suites is to follow defined environment management guidance that ensures test isolation and prevents flaky tests across different execution tiers.
