Homelab MCP Server

# CI/CD Test Strategy for Homelab MCP Server ## Current Test Status Analysis ### ✅ **CI/CD Ready Tests (248 passing)** - **Unit Tests**: All core business logic - **Configuration Tests**: 100% coverage ✅ - **Database Tests**: SQLite operations ✅ - **Error Handling Tests**: 99% coverage ✅ - **SSH Tools Tests**: Basic functionality ✅ - **VM Operations Tests**: Core VM management ✅ - **Migration Tests**: 93% coverage ✅ ### ⚠️ **Tests That Need CI/CD Adaptation (13 failing)** #### **Category 1: Integration Tests (7 failing)** - **Issue**: Require real network connectivity - **CI/CD Impact**: Will always fail in isolated CI environments - **Solution**: Mock network dependencies or mark as integration-only #### **Category 2: Ansible Service Tests (4 failing)** - **Issue**: Tests expect real Ansible execution - **CI/CD Impact**: Need proper mocking or Ansible installation - **Solution**: Enhanced mocking or containerized testing #### **Category 3: Migration Hash Tests (2 failing)** - **Issue**: Hash mocking inconsistencies - **CI/CD Impact**: Minor, easily fixable ## Recommendations for CI/CD Pipeline ### **Priority 1: Fix Critical CI/CD Blockers** 🚨 #### **1. Fix Remaining Unit Test Issues** ```python # Fix these 2 migration tests: - test_migrate_device_history_success (hash mocking) - test_full_migration_workflow_with_mocks (verification) ``` #### **2. Fix Ansible Service Tests** ```python # These 4 tests need proper mocking: - test_ansible_playbook_execution_success - test_ansible_playbook_execution_failure - test_ansible_variable_substitution - test_ansible_template_rendering ``` ### **Priority 2: Increase Coverage for Core Modules** 📊 #### **Critical Coverage Gaps** (Target for CI/CD) | Module | Current | Target | Missing Lines | |--------|---------|--------|---------------| | `service_installer.py` | 28% | **60%** | 353 lines | | `infrastructure_crud.py` | 32% | **50%** | 375 lines | | `server.py` | 43% | **60%** | 76 lines | | `database.py` | 50% | **70%** | 116 lines | ### **Priority 3: CI/CD Pipeline Configuration** ⚙️ #### **Test Categories for CI/CD** 1. **Unit Tests** (Fast, always run) - Core business logic - Configuration management - Error handling - Database operations (SQLite only) 2. **Integration Tests** (Slower, conditional) - Mock-based integration tests - Cross-module interaction tests - Service installer tests (mocked) 3. **End-to-End Tests** (Slowest, optional) - Full-stack integration (requires infrastructure) - Real network operations - Docker/container tests ## CI/CD Implementation Plan ### **Phase 1: Immediate (This Sprint)** #### **A. Fix Unit Test Failures** ⭐ - Fix 2 migration hash tests - Fix 4 Ansible service tests - **Goal**: 100% unit test pass rate #### **B. Separate Test Categories** ```bash # Unit tests (fast, always run) pytest tests/ -m "not integration and not e2e" # Integration tests (with mocking) pytest tests/ -m "integration and not e2e" # End-to-end tests (real infrastructure required) pytest tests/ -m "e2e" ``` ### **Phase 2: Coverage Improvements (Next Sprint)** #### **A. Service Installer Tests** (28% → 60%) - Add tests for Docker Compose service installation - Add tests for script-based installations - Add tests for Terraform service deployment - Add error handling tests #### **B. Infrastructure CRUD Tests** (32% → 50%) - Add tests for device configuration updates - Add tests for backup/restore operations - Add tests for scaling services - Add validation tests #### **C. Server Tests** (43% → 60%) - Add MCP protocol tests - Add tool execution tests - Add health endpoint tests - Add error response tests ### **Phase 3: Enhanced Testing (Future Sprint)** #### **A. Database Tests** (50% → 70%) - Add PostgreSQL adapter tests (mocked) - Add migration tests - Add performance tests - Add connection pooling tests #### **B. End-to-End Testing Infrastructure** - Docker Compose test environment - Mock SSH servers for testing - Containerized integration tests - Performance benchmarking ## GitHub Actions CI/CD Workflow ### **Recommended Workflow Structure** ```yaml name: CI/CD Pipeline on: [push, pull_request] jobs: # Fast unit tests (required to pass) unit-tests: runs-on: ubuntu-latest steps: - uses: actions/checkout@v3 - name: Setup Python uses: actions/setup-python@v4 with: python-version: '3.12' - name: Install dependencies run: | pip install uv uv sync - name: Run unit tests run: | uv run pytest tests/ -m "not integration and not e2e" --cov=src --cov-report=xml - name: Upload coverage uses: codecov/codecov-action@v3 # Integration tests (allowed to fail, but tracked) integration-tests: runs-on: ubuntu-latest continue-on-error: true steps: - uses: actions/checkout@v3 - name: Setup Python uses: actions/setup-python@v4 with: python-version: '3.12' - name: Install dependencies run: | pip install uv uv sync - name: Run integration tests run: | uv run pytest tests/ -m "integration and not e2e" --tb=short # Multi-platform testing cross-platform: strategy: matrix: os: [ubuntu-latest, windows-latest, macos-latest] python-version: ['3.11', '3.12'] runs-on: ${{ matrix.os }} steps: - uses: actions/checkout@v3 - name: Setup Python uses: actions/setup-python@v4 with: python-version: ${{ matrix.python-version }} - name: Install dependencies run: | pip install uv uv sync - name: Run core tests run: | uv run pytest tests/test_config.py tests/test_error_handling.py tests/test_database.py -v ``` ## Test Quality Gates for CI/CD ### **Required to Pass** ✅ - Unit tests: 100% pass rate - Core module coverage: >50% - No critical security issues - Code formatting (black, flake8) - Type checking (mypy) ### **Warning but Allow** ⚠️ - Integration test failures - Coverage below 70% (tracked but not blocking) - Performance regression <20% ### **Informational** ℹ️ - End-to-end test results - Performance benchmarks - Security scan results ## Next Steps ### **Immediate Actions** (This Week) 1. **Fix the 6 remaining unit test failures** 2. **Add test markers for categorization** 3. **Create basic GitHub Actions workflow** 4. **Set up coverage reporting** ### **Short Term** (Next 2 Weeks) 1. **Improve service_installer.py coverage to 60%** 2. **Add infrastructure_crud.py tests** 3. **Enhance server.py test coverage** 4. **Set up cross-platform testing** ### **Medium Term** (Next Month) 1. **Implement containerized integration testing** 2. **Add performance benchmarking** 3. **Set up automated security scanning** 4. **Create end-to-end test environments** ## Success Metrics - **Unit Test Pass Rate**: 100% - **Overall Coverage**: >60% - **CI/CD Pipeline Reliability**: >95% - **Cross-Platform Compatibility**: Windows, macOS, Linux - **Documentation Coverage**: All public APIs tested This strategy will give you a robust, CI/CD-ready test suite that can scale with your project while maintaining reliability and performance.
