Cover Async Routing Edge Cases
TEST-COVER-ASYNC-ROUTING-EDGE-CASES
Summary
Test late replies, unrelated input, timeouts, and unmatched async responses. These cases protect request correlation and cleanup without relying on wall-clock luck.
Rule
Cover unrelated input, late replies, timeouts, and unmatched responses in async routing tests.
Why
Async routing bugs often appear when replies arrive late, time out, match the wrong request, or include unrelated input. Happy-path tests can pass while the system leaks waiters, resolves the wrong caller, or drops important errors under concurrency.
Helps
- Protects request/response correlation, timeout behavior, and cleanup in async systems.
Limits
Do not make async tests depend on wall-clock luck. Prefer controlled clocks, channels, deterministic schedulers, or small timeouts only when the test remains stable.
Agent Instruction
Cover async routing cases for unrelated input, late replies, timeouts, unmatched responses, and
wrong-request matches.Mechanisms
Supported by fake clocks, controlled channels, task handles, deterministic timeout tests, unmatched-response fixtures, and state assertions after cancellation.
