+### Link Styling
+
+You can control the stroke pattern of the connection lines using `linkStyle`, a per-link callback like `linkColor`/`linkWidth`:
+
+```js
+var myTree = Treeviz.create({
+ htmlId: "tree",
+ idKey: "id",
+ hasFlatData: true,
+ relationnalField: "father",
+ linkStyle: (node) => {
+ // Return "solid", "dashed", "dotted", or "dashdot"
+ // Can vary per link based on node data:
+ return node.data.isOptional ? "dashed" : "solid";
+ },
+});
+```
+
+### Link Labels Configuration
+
+You can display labels on the connection lines between nodes using the `linkLabel` configuration:
+
+```js
+var myTree = Treeviz.create({
+ htmlId: "tree",
+ idKey: "id",
+ hasFlatData: true,
+ relationnalField: "father",
+ linkLabel: {
+ render: (parent, child) => {
+ // Return plain text to display on the connection line
+ return "is child";
+ // You can use parent and child data for dynamic labels:
+ // return child.data.name + " is child";
+ },
+ color: "#455A64", // Label text color (optional)
+ fontSize: 11 // Label font size in px (optional)
+ }
+});
+```
+
+The `render` function receives parent and child `NodeData` objects, allowing you to create dynamic labels based on node properties. Returns plain text only (HTML is not supported in SVG text elements).
+
+## Testing
+
+The project uses [Vitest](https://vitest.dev/) for unit and integration testing with jsdom for DOM simulation and coverage reporting.
+
+### Running Tests
+
+```bash
+# Run tests in watch mode
+npm test
+
+# Run tests once
+npm run test:run
+
+# Run tests with coverage report
+npm run test:coverage
+
+# Open Vitest UI dashboard (interactive)
+npm run test:ui
+```
+
+### Test Structure
+
+Tests are organized in `tests/` folder:
+
+- **`tests/unit/`** - Unit tests for individual functions and utilities
+ - `utils.test.ts` - Tests for `setNodeLocation()` function
+ - `core-utils.test.ts` - Tests for `getAreaSize()` and `RefreshQueue` class
+ - `node-ancestors.test.ts` - Tests for `getFirstDisplayedAncestor()` hierarchy traversal
+ - `prepare-data.test.ts` - Tests for data preparation and configuration validation
+
+- **`tests/integration/`** - Integration tests for API and configuration
+ - `treeviz-api.test.ts` - Tests for configuration validation, data variations, and layout configurations
+
+### Test Coverage
+
+Coverage reports are generated in the `coverage/` directory after running `npm run test:coverage`. The HTML report provides detailed coverage information for all source files.
+
## Contributing
- Clone the repo.
- Run `npm install`.
- Run `npm run dev`, then you can edit the files in the `./src` folder and the `./example/index.html` file.
+- **Run `npm test` to verify your changes pass all tests** before submitting a pull request.
- To publish (admin rights), run `npm run build && npm publish`.

+# Quick Start: Running Tests
+
+## Installation Complete ✅
+
+Vitest testing framework has been set up with jsdom environment and coverage support.
+
+## Test Commands
+
+```bash
+# Watch mode - auto-reruns tests on changes
+npm test
+
+# Single run - runs all tests once
+npm run test:run
+
+# Generate coverage report (HTML in coverage/ folder)
+npm run test:coverage
+
+# Interactive UI dashboard
+npm run test:ui
+```
+
+## Test Files Created
+
+### Unit Tests (tests/unit/)
+- ✅ **utils.test.ts** (5 tests)
+ - Tests for `setNodeLocation()` with various orientations
+
+- ✅ **core-utils.test.ts** (11 tests)
+ - Tests for `getAreaSize()` (valid/invalid containers)
+ - Tests for `RefreshQueue` class (async queue management)

+✅ Fast execution (no external dependencies)
+✅ Clear BDD-style test names
+
+## Example: Run Tests
+
+```bash
+# Install if needed
+npm install
+
+# Quick verification
+npm run test:run
+
+# Full coverage report
+npm run test:coverage
+# Open coverage/index.html to view detailed report
+```
+
+## Next: Check Test Results
+
+Run `npm run test:run` to see all 47 tests execute and verify the setup works correctly.

+# Running Example Tests - Quick Guide
+
+## 📋 What's in the Example Test?
+
+The `EXAMPLE_TEST_DEMO.test.ts` file contains real-world examples organized in 5 sections:
+
+### 1. **Organization Chart**
+Real data: CEO → CTO → Dev Lead → Frontend/Backend Devs
+- Tests coordinate positioning
+- Shows horizontal layout configuration
+
+### 2. **Family Trees**
+Three different data structures:
+- Simple linear (3 generations)
+- Wide tree (1 parent, 5 siblings)
+- Deep tree (5 generations)
+
+### 3. **Layout Configurations**
+- Horizontal layout
+- Vertical layout
+- Auto-spacing for responsive design
+
+### 4. **GitHub Repository Structure**
+Real-world: treeviz → src/ → nodes/, links/ + tests/ → unit/, integration/
+- Tests directory structure mapping
+- Tree traversal validation
+
+### 5. **Event Callbacks**
+- Click tracking
+- Mouse enter/leave events
+
+### 6. **DOM Container Setup**
+- SVG element creation
+- Container dimension testing
+

+
+## 🎯 Copy Patterns From Examples
+
+Use these patterns in your own tests:
+
+**1. Organization/Hierarchy Data**
+```typescript
+const data = [
+ { id: 'root', name: 'Root', parent: null },
+ { id: 'child', name: 'Child', parent: 'root' },
+];
+```
+
+**2. Configuration with All Options**
+```typescript
+const config: ITreeConfig = {
+ data: myData,
+ htmlId: 'container-id',
+ idKey: 'id',
+ relationnalField: 'parent',
+ hasFlatData: true,
+ nodeWidth: 150,
+ nodeHeight: 75,
+ mainAxisNodeSpacing: 300,
+ renderNode: (node) => node.data.name,
+ linkColor: () => '#1976d2',
+ linkWidth: () => 2,
+ isHorizontal: true,
+ hasPan: true,
+ hasZoom: true,
+ duration: 750,
+ onNodeClick: (node) => {},
+ onNodeMouseEnter: (node) => {},
+ onNodeMouseLeave: (node) => {},
+ marginTop: 40,
+ marginBottom: 40,
+ marginLeft: 60,
+ marginRight: 60,
+ secondaryAxisNodeSpacing: 1.5,
+};
+```
+
+**3. Testing Positioning**
+```typescript
+it('should position nodes correctly', () => {
+ const result = setNodeLocation(100, 400, config);
+ expect(result).toContain('translate');
+});
+```
+
+**4. Testing Data Validation**
+```typescript
+it('should handle tree structure', () => {
+ expect(data).toHaveLength(3);
+ expect(data[0].parent).toBeNull();
+});
+```
+
