# Test Implementation Summary
## ✅ What Has Been Implemented
### 1. Test Infrastructure
- **Jest Test Framework**: Configured for ES modules (.mjs files)
- **Test Directory Structure**: Organized into unit, integration, fixtures, and helpers
- **Test Scripts**: Added to package.json for easy execution
- **Coverage Reporting**: Configured with thresholds (70-80%)
- **CI/CD**: GitHub Actions workflow for automated testing
### 2. Unit Tests (✅ All Passing)
Location: `tests/unit/htmlUtils.test.mjs`
**33 passing tests** covering:
- `extractReadableText()` - 12 tests
- Simple HTML, complex HTML, nested structures
- Tables, lists, headings formatting
- XSS prevention (script/style tag removal)
- Unicode handling, malformed HTML
- Edge cases (empty, null, whitespace)
- `extractTextSummary()` - 7 tests
- Length limits, ellipsis handling
- Empty content, custom lengths
- Unicode in summaries
- `textToHtml()` - 14 tests
- Markdown to HTML conversion
- Headers, bold, italic, links, code blocks
- Lists, blockquotes, horizontal rules
- XSS prevention via HTML escaping
- Mixed formatting
### 3. Integration Tests (⚠️ Template/Examples)
Location: `tests/integration/`
**Authentication Tests** (`authentication.test.mjs`) - **20 passing tests**:
- Token file management (JSON and legacy formats)
- Token validation and expiration detection
- Client ID configuration
- Required scopes verification
- Error handling for corrupted/missing files
**MCP Tools Tests** (`mcpTools.test.mjs`) - **23 example tests**:
- Demonstrates how to mock Microsoft Graph API
- Examples for all major MCP tools
- Error handling patterns (429, 401, 404)
- Response validation patterns
- **Note**: These are templates showing testing approach
### 4. Test Fixtures & Helpers
- `tests/fixtures/htmlContent.mjs` - 8 HTML test cases
- `tests/fixtures/apiResponses.mjs` - Mock Graph API responses
- `tests/helpers/mockFactory.mjs` - Nock-based API mocking utilities
- `tests/helpers/testUtils.mjs` - General test utilities
### 5. Documentation
- **TESTING.md**: Comprehensive testing guide with:
- Quick start instructions
- Test structure explanation
- How to write new tests
- Coverage requirements
- Troubleshooting guide
- Best practices
### 6. CI/CD Pipeline
- **GitHub Actions** (`.github/workflows/test.yml`):
- Runs on push/PR to main/develop
- Tests on Ubuntu, macOS, Windows
- Node.js versions: 18.x, 20.x, 22.x
- Includes security audit
- Uploads coverage reports
## 📊 Current Test Status
```text
Unit Tests: 33/33 passing ✅
Authentication: 20/20 passing ✅
MCP Tools: Templates (require Graph client abstraction)
Total Passing: 53 tests
```
## 🚀 Quick Start
```bash
# Install dependencies
npm install
# Run all tests
npm test
# Run only unit tests (recommended to start)
npm run test:unit
# Run with coverage
npm run test:coverage
# Watch mode for development
npm run test:watch
```
## 📁 File Structure Created

## 🔄 Running Tests Repeatedly
The test structure is designed for continuous use:
1. **During Development**:
```bash
npm run test:watch
```
Tests run automatically when you save files.
2. **Before Commits**:
```bash
npm test
```
Ensures all tests pass.
3. **On GitHub (Automatic)**:
- Tests run automatically on push/PR
- Results appear in PR checks
- Coverage reports uploaded
## 📝 Adding New Tests
### For New Utility Functions
1. Add test file to `tests/unit/`
2. Import function and `@jest/globals`
3. Write test cases with `describe()` and `it()`
4. Run `npm run test:unit` to verify
### For New MCP Tools
1. Use `tests/integration/mcpTools.test.mjs` as template
2. Create mocks in `tests/helpers/mockFactory.mjs`
3. Add test fixtures to `tests/fixtures/`
4. Run `npm run test:integration` to verify
## 🎯 Next Steps (Optional Enhancements)
1. **Expand Integration Tests**:
- Refactor `onenote-mcp.mjs` to export testable functions
- Create proper dependency injection for Graph client
- Complete integration test coverage for all 20 tools
2. **Add E2E Tests**:
- Optional manual E2E test scripts
- Real OneNote environment testing
3. **Performance Tests**:
- Large HTML document processing
- Pagination with 100+ pages
- Concurrent request handling
4. **Snapshot Tests**:
- HTML output snapshot testing
- Markdown conversion snapshots
