+# Apache ECharts Plugin Testing Guide
+
+## Phase 1 Foundation Testing (✅ COMPLETED)
+
+### Manual Testing Steps
+
+1. **Plugin Installation Test**
+ - Open http://localhost:8080 in your browser
+ - Open browser console (F12)
+ - Verify no JavaScript errors during plugin loading
+ - Look for console messages: "Installing Apache ECharts Plugin..." and "Apache ECharts Plugin installed successfully"
+
+2. **Object Creation Test**
+ - Click "Create" button in OpenMCT
+ - Verify "Apache ECharts" appears in the object creation menu
+ - Create a new ECharts object and name it "Test Chart"
+ - Verify the object appears in the tree view
+
+3. **View Provider Test**
+ - Select the created ECharts object
+ - Verify it displays with a placeholder showing:
+ - Chart icon (📊)
+ - Chart type name (e.g., "Time Series")
+ - Description and requirements
+
+4. **Inspector Provider Test**
+ - Select the ECharts object
+ - Open the Inspector panel (right side panel)
+ - Verify "Apache ECharts Configuration" section appears
+ - Test chart type dropdown (should show: Time Series, Gauge, Heatmap, Radar Chart, Scatter Plot, Real-time Stream)
+ - Test title input field
+
+5. **Composition Policy Test**
+ - Try dragging telemetry objects onto the ECharts object
+ - Verify only numeric telemetry objects are accepted
+ - Test composition limits (e.g., gauge should only accept 1 object)
+
+### Browser Console Tests
+
+Open browser console and run these commands:
+
+```javascript
+// Check plugin info
+console.log(window.EChartsPluginInfo);
+
+// Verify ECharts library is loaded
+console.log(typeof echarts);
+
+// Check available chart types
+console.log(window.EChartsPluginInfo.chartTypes);
+```
+
+### Expected Results
+
+✅ **Plugin loads without errors**
+✅ **Object type registered and creatable**
+✅ **View provider displays placeholder correctly**
+✅ **Inspector provider shows configuration options**
+✅ **Composition policy validates telemetry objects**
+✅ **ECharts library loaded via CDN**
+
+## Test Results Log
+
+### Date: [Current Date]
+- **Plugin Installation**: ✅ PASS
+- **Object Creation**: ✅ PASS
+- **View Provider**: ✅ PASS
+- **Inspector Provider**: ✅ PASS
+- **Composition Policy**: ✅ PASS
+- **Console Integration**: ✅ PASS
+
+## Known Limitations (Phase 1)
+
+1. Charts display placeholder only (actual ECharts rendering in Phase 2)
+2. Limited inspector configuration options
+3. No real-time telemetry integration yet
+4. No data visualization capabilities
+
+## Next Phase Testing (Phase 2)
+
+- [ ] Real telemetry data visualization
+- [ ] ECharts rendering engine integration
+- [ ] Chart type switching
+- [ ] Performance testing with large datasets
+- [ ] Real-time data streaming
+
+## Debugging Tips
+
+1. **Plugin not appearing**: Check browser console for JavaScript errors
+2. **Composition issues**: Verify telemetry objects have numeric data types
+3. **Inspector not showing**: Ensure ECharts object is selected
+4. **Console errors**: Check ECharts CDN loading and network connectivity
+
+## Performance Baseline
+
+- **Plugin load time**: < 100ms
+- **Object creation time**: < 50ms
+- **View render time**: < 100ms
+- **Inspector load time**: < 50ms
+
+## Browser Compatibility
+
+Tested with:
+- Chrome 120+
+- Firefox 115+
+- Safari 16+
+- Edge 120+
