To prevent Effect-TS tests from hanging in CI, enforce explicit timeout flags like --timeout 15000 on every test execution to avoid hung event loops and ensure deterministic test behavior.

False-positive test outcomes in Effect-TS happen when error paths go untested. Use Effect.flip to convert errors into testable values, ensuring error scenarios are explicitly asserted rather than silently passing green.

To isolate tests using Layer composition in Effect-TS, create per-test Layer factories that provide fresh state for each test, preventing state leakage and ensuring deterministic multi-turn kernel test behavior.

Bun test runner works with Effect-TS for TDD by enforcing mandatory timeouts, using Effect.flip for error-path assertions, and requiring explicit server teardown to maintain CI stability.

The best way to clean up local server bindings after integration tests is to enforce explicit server shutdown using afterAll teardown blocks to prevent dangling servers and resource leaks in CI.

Use per-test Layer factories instead of shared Layers during unit, integration, and multi-turn kernel tests to guarantee test isolation, prevent state leakage, and satisfy CI stability requirements.
