Test Plugins Created:
- api_comprehensive_test: 60+ tests covering all PluginAPI, WidgetAPI, ExternalAPI methods
- widget_stress_test: Stress testing widget creation, layouts, and operations
- external_integration_test: REST server, webhooks, auth, and IPC testing
- event_bus_test: Pub/sub messaging system validation
- performance_benchmark: Latency, throughput, and resource usage metrics
- error_handling_test: Edge cases, exceptions, and error condition handling

Features:
- HTML-based visual results displays
- Pass/fail tracking with detailed error reporting
- Automated test execution on initialization
- JSON export for CI/CD integration
- Comprehensive documentation in README.md

Each plugin follows BasePlugin pattern with:
- Proper manifest.json with test metadata
- Interactive UI widgets for results
- Categorized test coverage
- Performance metrics collection

# EU-Utility Test Suite
Comprehensive test plugins for validating the Three-Tier API (PluginAPI, WidgetAPI, ExternalAPI).
## Test Plugins Overview
### 1. API Comprehensive Test (`api_comprehensive_test/`)
**Purpose:** Tests every method across all three API tiers
**Coverage:**
- **PluginAPI (12 services, 30+ tests):**
- Log Reader: `read_log_lines()`, `read_log_since()`
- Window Manager: `get_eu_window()`, `is_eu_focused()`, `is_eu_visible()`, `bring_eu_to_front()`
- OCR: `recognize_text()`, `ocr_available()`
- Screenshot: `capture_screen()`, `screenshot_available()`
- Nexus: `search_items()`, `get_item_details()`
- HTTP: `http_get()`, `http_post()`
- Audio: `play_sound()`, `beep()`
- Notifications: `show_notification()`
- Clipboard: `copy_to_clipboard()`, `paste_from_clipboard()`
- EventBus: `subscribe()`, `unsubscribe()`, `publish()`
- DataStore: `get_data()`, `set_data()`, `delete_data()`
- Tasks: `run_task()`, `cancel_task()`
- **WidgetAPI (25+ tests):**
- Creation: `create_widget()`, `create_from_preset()`
- Access: `get_widget()`, `get_all_widgets()`, `get_visible_widgets()`, `widget_exists()`
- Management: `show_widget()`, `hide_widget()`, `close_widget()`, `show_all_widgets()`, etc.
- Instance methods: `show()`, `hide()`, `move()`, `resize()`, `set_opacity()`, etc.
- Layout: `arrange_widgets()`, `snap_to_grid()`
- Persistence: `save_all_states()`, `load_all_states()`, `save_state()`, `load_state()`
- **ExternalAPI (15+ tests):**
- Server: `start_server()`, `stop_server()`, `get_status()`
- Endpoints: `register_endpoint()`, `unregister_endpoint()`, `@endpoint` decorator
- Webhooks: `register_webhook()`, `unregister_webhook()`, `post_webhook()`
- Auth: `create_api_key()`, `revoke_api_key()`
- IPC: `register_ipc_handler()`, `send_ipc()`
**Features:**
- Visual HTML-based results display
- Pass/fail tracking for each test
- Error reporting with details
- Results export to JSON
---
### 2. Widget Stress Test (`widget_stress_test/`)
**Purpose:** Tests widget system under load
**Test Scenarios:**
- **Bulk Creation:** Creates 10-50 widgets rapidly
- **Layout Stress:** Tests grid, horizontal, vertical, cascade arrangements
- **Visibility Cycles:** Rapid show/hide operations
- **Property Modifications:** Rapid opacity, position, size changes
- **Concurrent Operations:** Create while modifying
**Metrics:**
- Operation count
- Duration (ms)
- Success rate
- Error tracking
---
### 3. External Integration Test (`external_integration_test/`)
**Purpose:** Tests third-party integration features
**Test Categories:**
- **REST Server:** Start/stop lifecycle, endpoint registration, CORS
- **Webhooks:** Incoming/outgoing, HMAC signature verification
- **Authentication:** API key creation/revocation
- **IPC:** Handler registration, message sending
- **Utilities:** Status endpoint, URL generation, webhook history
---
### 4. Event Bus Test (`event_bus_test/`)
**Purpose:** Tests pub/sub messaging system
**Test Coverage:**
- Basic subscribe/publish
- Unsubscribe functionality
- Multiple subscribers to single event
- Various data types (string, int, dict, list, nested)
- Wildcard/pattern subscriptions
- High-volume publishing (100 events)
- Rapid subscribe/unsubscribe cycles
- Empty/null event data
- Large payloads
- Special characters in event types
**Visualization:**
- Real-time event log
- Delivery statistics
- Performance metrics
---
### 5. Performance Benchmark (`performance_benchmark/`)
**Purpose:** Measures API performance metrics
**Benchmarks:**
- **DataStore:** Read/write operations (1000+ iterations)
- **EventBus:** Publish/subscribe throughput
- **HTTP:** Network request latency
- **WidgetAPI:** Creation and operation speed
- **ExternalAPI:** Key and endpoint registration
**Metrics:**
- Average latency (ms)
- Min/max latency
- Throughput (ops/sec)
- Total operations
**Output:**
- Interactive results table
- Performance grades (Good/Slow)
- Export to JSON
---
### 6. Error Handling Test (`error_handling_test/`)
**Purpose:** Tests error conditions and exception handling
**Error Types Tested:**
- Invalid input
- Service unavailable
- Resource not found
- Type errors
- Timeout
- Boundary conditions
**Test Counts:**
- PluginAPI: 15+ error scenarios
- WidgetAPI: 10+ error scenarios
- ExternalAPI: 10+ error scenarios
**Verification:**
- Graceful error handling (no crashes)
- Correct exception types
- Meaningful error messages
---
## Running the Tests
### Automatic Execution
All test plugins run automatically on initialization and display results in their widget.
### Manual Execution
Each plugin provides control buttons to:
- Run all tests
- Run specific test categories
- Clear results
- Export data
### Expected Results
- **Comprehensive Test:** 60+ tests
- **Stress Test:** 6+ stress scenarios
- **Integration Test:** 12+ integration tests
- **Event Bus Test:** 12+ messaging tests
- **Performance Benchmark:** 8+ benchmarks
- **Error Handling Test:** 35+ error scenarios
---
## Test Metadata
Each plugin includes `manifest.json` with:
```json
{
"test_metadata": {
"test_type": "comprehensive|stress|integration|messaging|performance|error_handling",
"apis_tested": ["PluginAPI", "WidgetAPI", "ExternalAPI"],
"automated": true
}
}
```

---
## Continuous Integration
These plugins can be used in CI pipelines:
1. Load plugin
2. Wait for initialization
3. Parse results from exported JSON
4. Fail build on critical test failures
---
## Maintenance
When adding new API features:
1. Add corresponding tests to `api_comprehensive_test`
2. Add performance benchmark if applicable
3. Add error handling tests for edge cases
4. Update this README

**Last Updated:** 2026-02-15
**Compatible with:** EU-Utility API v2.2.0+
