Description

Goal: Fix the intermittent test failure in messageFlows.test.js where "Expected done to be called once, but it was called multiple times."

Problem: The integration test for empty query handling has a race condition that causes it to fail randomly. This indicates improper cleanup or multiple event handlers being triggered.

Solution:

  • Review the test cleanup logic in __tests__/integration/messageFlows.test.js
  • Ensure proper connection teardown and event handler cleanup
  • Add proper synchronization to prevent multiple done() calls

Contributor guide

Research direction
Inspect the test cleanup logic in ` tests /integration/messageFlows.test.js`. Ensure proper connection teardown and remove duplicate event handlers to prevent multiple `done()` calls.
