### Running UI Tests (yarn test:ui)
The UI tests require specific setup in the test environment:
**Prerequisites:**
1. **Xvfb (X Virtual Framebuffer)** - Required for headless Electron testing
```bash
# Start Xvfb on display :99
Xvfb :99 -screen 0 1024x720x24 -ac &
export DISPLAY=:99
```
2. **Mosquitto MQTT Broker** - Required for MQTT message testing
```bash
# Install mosquitto
sudo apt-get install -y mosquitto mosquitto-clients
# Start mosquitto service
sudo systemctl start mosquitto
# Verify it's running on port 1883
sudo systemctl status mosquitto
```
3. **@types/node** - Required for TypeScript compilation
```bash
yarn add -D @types/node
```
**Running UI Tests:**
```bash
# Build the application first
yarn build
# Run UI tests with proper display
DISPLAY=:99 yarn test:ui
```
**Common Issues:**
- **"Timeout exceeded" in before hook**: Mosquitto is not running or not accessible on port 1883
- **"Cannot find type definition file for 'node'"**: Run `yarn add -D @types/node`
- **Electron fails to launch**: Xvfb is not running or DISPLAY variable not set
- **Tests hang**: Check if old Electron/mosquitto processes are still running and kill them
**Environment Cleanup:**
```bash
# Kill old Electron processes
ps aux | grep electron | grep -v grep | awk '{print $2}' | xargs kill -9 2>/dev/null
# Kill old mosquitto processes (if running custom instance)
ps aux | grep mosquitto | grep -v grep | awk '{print $2}' | xargs kill -9 2>/dev/null
```

*

* 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

/** /**
* UI Test Suite for MQTT Explorer * MQTT Explorer UI Tests - Fully Isolated Test Suite
* *
* These tests validate the core UI functionality of MQTT Explorer. * Each test:
* Each test is independent and deterministic. * 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
* *
* Best Practices Applied: * This ensures complete test isolation with no state carryover.
* - 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`
