/**
* UI Test Suite for MQTT Explorer
*
* These tests validate the core UI functionality of MQTT Explorer.
* Each test is independent and deterministic.
*
* Best Practices Applied:
* - Wait for specific UI elements rather than fixed timeouts
* - Use meaningful assertions that verify actual state
* - Test data-driven scenarios (Given-When-Then pattern)
* - Capture screenshots for visual verification
* - Handle MQTT asynchronous operations properly
*
* Prerequisites:
* - MQTT broker running on localhost:1883
* - Application built with `yarn build`
* MQTT Explorer UI Tests - Fully Isolated Test Suite
*
* Each test:
* 1. Gets fresh page
* 2. Mocks only the MQTT messages it needs (no timers)
* 3. Connects to broker
* 4. Tests functionality using expandTopic
* 5. Reloads page for next test
*
* This ensures complete test isolation with no state carryover.
