🧪 test: implement Phase 3 parallel testing infrastructure

Browse Source 
- Added port management system with PortManager for parallel execution
- Implemented resource monitoring with ResourceMonitor and ParallelTestRunner
- Created test-all-features-parallel.sh for parallel feature test execution
- Added comprehensive BDD_TAGS.md documentation for tag usage
- Implemented port allocation, conflict detection, and resource tracking
- Added timeout detection and controlled parallelism

# BDD Test Tags Documentation
This document describes the tagging system used in the dance-lessons-coach BDD tests for selective test execution.
## Tag Categories
### Feature Tags
Used to categorize tests by feature area:
- `@auth` - Authentication and user management tests
- `@config` - Configuration and hot reloading tests
- `@greet` - Greeting service tests
- `@health` - Health check and monitoring tests
- `@jwt` - JWT secret rotation and retention tests
### Priority Tags
Used to categorize tests by importance:
- `@smoke` - Basic smoke tests that verify core functionality
- `@critical` - Critical path tests that must always pass
- `@basic` - Basic functionality tests
- `@advanced` - Advanced or edge case scenarios
### Component Tags
Used to categorize tests by system component:
- `@api` - API endpoint tests
- `@v2` - Version 2 API tests
- `@database` - Database interaction tests
- `@security` - Security-related tests
## Usage Examples
### Running Smoke Tests
```bash
# Run all smoke tests
godog --tags=@smoke features/
# Run smoke tests for specific feature
godog --tags=@smoke features/auth/
```
### Running Critical Tests
```bash
# Run all critical tests
godog --tags=@critical features/
# Run critical health tests
godog --tags=@critical,@health features/
```
### Running Feature-Specific Tests
```bash
# Run all auth tests
godog --tags=@auth features/
# Run v2 API tests
godog --tags=@v2 features/
```
### Combining Tags
```bash
# Run smoke tests for auth and health features
godog --tags=@smoke,@auth,@health features/
# Run critical API tests
godog --tags=@critical,@api features/
```
## Tagging Conventions
1. **Feature tags** should be applied at the feature level
2. **Priority tags** should be applied at the scenario level
3. **Component tags** should be applied at the scenario level
4. **Multiple tags** can be applied to a single scenario
### Example Feature File
```gherkin
@health @smoke
Feature: Health Endpoint
The health endpoint should indicate server status
@basic @critical
Scenario: Health check returns healthy status
Given the server is running
When I request the health endpoint
Then the response should be "{\"status\":\"healthy\"}"
@advanced @api
Scenario: Health check with authentication
Given the server is running with auth enabled
When I request the health endpoint with valid token
Then the response should be "{\"status\":\"healthy\"}"
```
## Test Execution Scripts
### Feature-Specific Testing
```bash
# Test specific feature
./scripts/test-feature.sh greet
# Test with specific tags
./scripts/test-by-tag.sh @smoke greet
```
### Tag-Based Testing
```bash
# Run smoke tests for all features
./scripts/test-by-tag.sh @smoke
# Run critical auth tests
./scripts/test-by-tag.sh @critical auth
```
## CI/CD Integration
### Smoke Test Pipeline
```yaml
- name: Run Smoke Tests
run: godog --tags=@smoke features/
```
### Critical Path Testing
```yaml
- name: Run Critical Tests
run: godog --tags=@critical features/
```
### Feature-Specific Testing
```yaml
- name: Test Auth Feature
run: ./scripts/test-feature.sh auth
```
## Best Practices
1. **Tag consistently** - Apply tags consistently across similar scenarios
2. **Prioritize tests** - Use priority tags to identify critical tests
3. **Document tags** - Keep this documentation updated with new tags
4. **Review tags** - Regularly review tag usage to ensure relevance
5. **CI/CD optimization** - Use tags to optimize CI/CD pipeline execution times
## Tag Reference
| Tag | Purpose | Example Usage |
|-----|---------|--------------|
| `@smoke` | Smoke tests | `@smoke` on critical features |
| `@critical` | Critical path | `@critical` on essential scenarios |
| `@basic` | Basic functionality | `@basic` on standard scenarios |
| `@advanced` | Advanced scenarios | `@advanced` on edge cases |
| `@auth` | Authentication | `@auth` on auth features |
| `@config` | Configuration | `@config` on config scenarios |
| `@api` | API endpoints | `@api` on endpoint tests |
| `@v2` | V2 API | `@v2` on version 2 tests |
## Future Enhancements
- **Performance tags** - `@fast`, `@slow` for performance categorization
- **Environment tags** - `@ci`, `@local` for environment-specific tests
- **Risk tags** - `@high-risk`, `@low-risk` for risk-based testing
- **Automated tag validation** - Script to validate tag usage consistency
