## 🎨 Test Categories
### 1. Unit Tests
**Purpose**: Test individual functions and components in isolation
```typescript
// Example: Function unit test
describe('generateAdrFromDecision', () => {
it('should generate ADR with proper structure', async () => {
const decision = {
title: 'Use React for Frontend',
context: 'Need modern UI framework',
decision: 'Adopt React 18',
};
const result = await generateAdrFromDecision(decision);
expect(result.title).toBe('Use React for Frontend');
expect(result.status).toBe('proposed');
expect(result.content).toContain('## Context');
});
});
```
### 2. Integration Tests
**Purpose**: Test tool interactions and workflows
```typescript
// Example: Integration test
describe('Memory System Integration', () => {
it('should load ADRs and query entities', async () => {
// Load ADRs into memory
const loadResult = await memoryTool.execute({
action: 'load_adrs',
forceReload: true,
});
expect(loadResult.isError).toBeFalsy();
// Query loaded entities
const queryResult = await memoryTool.execute({
action: 'query_entities',
query: { entityTypes: ['architectural_decision'] },
});
expect(queryResult.entities.length).toBeGreaterThan(0);
});
});
```
### 3. Tool Tests
**Purpose**: Test MCP tool functionality and parameters
```typescript
// Example: Tool test
describe('analyze_project_ecosystem', () => {
it('should analyze project with enhanced mode', async () => {
const result = await analyzeProjectEcosystem({
projectPath: '/test/project',
enhancedMode: true,
knowledgeEnhancement: true,
analysisDepth: 'comprehensive',
});
expect(result.content).toBeDefined();
expect(result.confidence).toBeGreaterThan(0.8);
expect(result.technologies).toContain('typescript');
});
});
```
### 4. Prompt Tests
**Purpose**: Validate prompt generation and AI integration
```typescript
// Example: Prompt test
describe('generateAdrSuggestionPrompt', () => {
it('should generate comprehensive prompt', () => {
const prompt = generateAdrSuggestionPrompt({
projectContext: 'React application',
technologies: ['react', 'typescript'],
analysisResults: mockAnalysis,
});
expect(prompt).toContain('React application');
expect(prompt).toContain('typescript');
expect(prompt.length).toBeGreaterThan(100);
});
});
```
### 5. Performance Tests
**Purpose**: Validate system performance and resource usage
```typescript
// Example: Performance test
describe('Memory Performance', () => {
it('should handle large entity sets efficiently', async () => {
const startTime = Date.now();
const entities = generateLargeEntitySet(1000);
await memoryManager.batchUpsertEntities(entities);
const duration = Date.now() - startTime;
expect(duration).toBeLessThan(5000); // 5 seconds max
});
});
```

## ✍️ Writing New Tests
### Test File Template
```typescript
/**
* Test file for [COMPONENT_NAME]
*
* Tests cover:
* - Basic functionality
* - Edge cases
* - Error handling
* - Integration scenarios
*/
import { describe, it, expect, beforeEach, afterEach } from '@jest/globals';
import { [COMPONENT_NAME] } from '../src/path/to/component.js';
describe('[COMPONENT_NAME]', () => {
beforeEach(() => {
// Setup before each test
});
afterEach(() => {
// Cleanup after each test
});
describe('basic functionality', () => {
it('should perform expected operation', () => {
// Test implementation
expect(true).toBe(true);
});
});
describe('edge cases', () => {
it('should handle empty input', () => {
// Edge case testing
});
});
describe('error handling', () => {
it('should throw on invalid input', () => {
expect(() => {
// Error condition
}).toThrow();
});
});
});
```
### Testing Best Practices
#### 1. Test Structure (AAA Pattern)
```typescript
it('should describe what it tests', () => {
// Arrange - Set up test data
const input = { test: 'data' };
// Act - Execute the function
const result = functionUnderTest(input);
// Assert - Verify the result
expect(result).toBe(expectedValue);
});
```
#### 2. Descriptive Test Names
```typescript
// ❌ Bad
it('should work', () => {});
// ✅ Good
it('should generate ADR with proper MADR format when template is specified', () => {});
```
#### 3. Test Data Management
```typescript
// Use factories for complex test data
const createMockAnalysis = (overrides = {}) => ({
projectPath: '/test/project',
technologies: ['typescript', 'react'],
confidence: 0.95,
...overrides,
});
```
#### 4. Async Testing
```typescript
// Proper async test handling
it('should handle async operations', async () => {
const result = await asyncFunction();
expect(result).toBeDefined();
});
```
### Test Coverage Requirements
- **Minimum Coverage**: 80% (currently exceeding this)
- **Function Coverage**: All exported functions must be tested
- **Branch Coverage**: All conditional branches tested
- **Integration Coverage**: All tool interactions tested
---
## 🔄 CI/CD Integration
### GitHub Actions Workflow
The test suite runs automatically on:
- **Pull Requests**: All tests must pass
- **Push to Main**: Full test suite execution
- **Scheduled**: Daily test runs for regression detection
```yaml
# .github/workflows/test.yml
name: Test Suite
on: [push, pull_request]
jobs:
test:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- uses: actions/setup-node@v4
with:
node-version: '20'
- run: npm ci
- run: npm test
- run: npm run test:coverage
```
### Pre-commit Hooks
Tests run automatically before commits:
```bash
# .husky/pre-commit
#!/usr/bin/env sh
npm run lint
npm test
npm run build
```
### Quality Gates
- **Zero Failing Tests**: No commits allowed with failing tests
- **Coverage Threshold**: Must maintain >80% coverage
- **Performance Regression**: Tests must complete within time limits
- **Security Validation**: Security-focused tests must pass
---
## 🔧 Troubleshooting Tests
### Common Test Issues
#### 1. Memory/Timeout Issues
```bash
# Increase Jest timeout
npm test -- --testTimeout=30000
# Run tests with more memory
node --max-old-space-size=4096 node_modules/.bin/jest
```
#### 2. Path Resolution Issues
```typescript
// Use dynamic path resolution
import { fileURLToPath } from 'url';
import { dirname, join } from 'path';
const __filename = fileURLToPath(import.meta.url);
const __dirname = dirname(__filename);
const testWorkspace = join(__dirname, '../../test-workspace');
```
#### 3. Mock Issues
```typescript
// Proper mock cleanup
afterEach(() => {
jest.clearAllMocks();
jest.resetModules();
});
```
#### 4. Tree-sitter Parser Issues
```bash
# Tree-sitter parsers may fail in test environment
# Tests gracefully handle parser failures
console.warn('Tree-sitter parser failed, falling back to regex analysis');
```
### Debugging Tests
```bash
# Run single test with debugging
node --inspect-brk node_modules/.bin/jest tests/specific-test.test.ts
# Run with verbose logging
DEBUG=* npm test
# Run with Jest debugging
npm test -- --detectOpenHandles --forceExit
```
---
## ⚡ Performance Testing
### Performance Test Categories
#### 1. Memory Performance
```typescript
describe('Memory Performance', () => {
it('should handle large datasets efficiently', async () => {
const startMemory = process.memoryUsage().heapUsed;
// Perform memory-intensive operation
await processLargeDataset();
const endMemory = process.memoryUsage().heapUsed;
const memoryIncrease = endMemory - startMemory;
expect(memoryIncrease).toBeLessThan(100 * 1024 * 1024); // 100MB limit
});
});
```
#### 2. Execution Time Performance
```typescript
describe('Execution Performance', () => {
it('should complete analysis within time limit', async () => {
const startTime = performance.now();
await analyzeProjectEcosystem({ projectPath: '/large/project' });
const duration = performance.now() - startTime;
expect(duration).toBeLessThan(10000); // 10 second limit
});
});
```
#### 3. Concurrent Operation Performance
```typescript
describe('Concurrency Performance', () => {
it('should handle multiple simultaneous requests', async () => {
const requests = Array(10)
.fill()
.map(() => analyzeContentSecurity({ content: 'test content' }));
const results = await Promise.all(requests);
expect(results).toHaveLength(10);
results.forEach(result => {
expect(result.isError).toBeFalsy();
});
});
});
```
