Feature: Comprehensive test suite for CI/CD

Status update — 2026-09-11

The original "No automated tests" / "No CI/CD validation" statements below are historical. At reviewed main commit b4da033 (1.2.4), PR #47 has landed 17 core tests and shared fixtures; pytest configuration also exists. The existing Windows/Ubuntu CI workflow compiles the package and performs a dry-run, but does not execute pytest.

Detailed defects, guarded local reproduction (16 passed, 1 failed), and the minimum test corrections are tracked in #10. Passing counts alone are insufficient: the success test currently passes even when process execution fails.

• Complete the mock and assertion corrections tracked in #10.
• Add a pytest step to the existing Windows/Ubuntu matrix; initially run python -m pytest -q tests/test_core.py after installing dependencies and pytest.
• Add coverage tooling/report generation and document the measured scope. Neither this issue's 70% goal nor #10's 80%+ core-function goal has been verified.
• Track broader integration/functional coverage separately from the minimum PR #47 follow-up.

PR #47 is merged; these are follow-up acceptance tasks, not merge-conflict resolution. Source: reviewed CI workflow.

Feature: Comprehensive Test Suite

Description\nAdd comprehensive pytest-based test suite for automated testing in CI/CD pipelines.\n\n### Current State\n- No automated tests\n- Manual testing only\n- No CI/CD validation\n\n### Proposed Test Categories\n\n#### 1. Unit Tests (70% coverage)\n\ntests/\n├── unit/\n│ ├── test_dc_detection.py\n│ ├── test_dns_resolution.py\n│ ├── test_ldap_enumeration.py\n│ ├── test_smb_enumeration.py\n│ ├── test_email_protocols.py\n│ ├── test_cve_registry.py\n│ └── test_ntds_dump_service.py\n\n\n#### 2. Integration Tests (15% coverage)\n\ntests/integration/\n├── test_with_mock_dc.py\n├── test_with_docker_ad.py\n└── test_with_mock_services.py\n\n\n#### 3. Functional Tests (10% coverage)\n\ntests/functional/\n├── test_dry_run_execution.py\n├── test_active_scan.py\n└── test_output_formats.py\n\n\n#### 4. Security Tests (5% coverage)\n\ntests/security/\n├── test_credential_handling.py\n├── test_no_secrets_in_output.py\n└── test_ssl_verification.py\n\n\n### Test Examples\n\n#### Unit Test: DC Detection\npython\ndef test_dns_srv_query_timeout():\n \"\"\"Test graceful handling of DNS timeouts\"\"\"\n with pytest.raises(TimeoutError):\n query_dns_srv(\"invalid.domain\", timeout=1)\n\ndef test_ldap_fallback_on_dns_failure():\n \"\"\"Test LDAP fallback when DNS fails\"\"\"\n result = detect_dcs(\"domain\", fallback=True)\n assert len(result) > 0\n\n\n#### Integration Test: Mock AD Environment\npython\n@pytest.fixture\ndef mock_ad_server():\n \"\"\"Spin up mock AD server for testing\"\"\"\n server = MockADServer()\n server.start()\n yield server\n server.stop()\n\ndef test_ad_enumeration(mock_ad_server):\n result = enumerate_ad(mock_ad_server.host)\n assert result[\"domain\"] == \"mock.local\"\n\n\n### GitHub Actions CI/CD\n\nyaml\nname: Tests\non: [push, pull_request]\njobs:\n test:\n runs-on: ubuntu-latest\n strategy:\n matrix:\n python-version: ['3.10', '3.11', '3.12']\n steps:\n - uses: actions/checkout@v3\n - name: Set up Python\n uses: actions/setup-python@v4\n with:\n python-version: ${{ matrix.python-version }}\n - name: Install dependencies\n run: pip install -e .[dev]\n - name: Run tests\n run: pytest --cov=adpentest tests/\n - name: Upload coverage\n run: codecov\n - name: Lint\n run: flake8 adpentest tests\n - name: Type check\n run: mypy adpentest\n\n\n### Test Coverage Goals\n- Unit tests: 70% code coverage\n- Integration tests: Key workflows\n- All new features must include tests\n- Pre-commit hooks validate tests pass\n\n### Dependencies\ntoml\n[project.optional-dependencies]\ndev = [\n \"pytest>=7.0\",\n \"pytest-cov>=4.0\",\n \"pytest-mock>=3.10\",\n \"pytest-asyncio>=0.20\",\n \"pytest-timeout>=2.1\",\n \"mock-ad-server>=1.0\", # Mock Active Directory\n \"responses>=0.20\", # Mock HTTP responses\n]\n\n\n### Implementation Tasks\n- [ ] Set up pytest configuration\n- [ ] Create test fixtures and mocks\n- [ ] Write unit tests (DC detection, DNS, LDAP, SMB)\n- [ ] Write integration tests with mock AD\n- [ ] Write functional tests\n- [ ] Add GitHub Actions CI/CD pipeline\n- [ ] Achieve 70% code coverage\n- [ ] Document testing guidelines\n- [ ] Add pre-commit hooks\n\n### Benefits\n- ✅ Catch bugs early\n- ✅ Enable refactoring safely\n- ✅ Document expected behavior\n- ✅ Increase code quality\n- ✅ Reduce manual testing burden\n\n### Priority\nHigh - Essential for production-grade software\n

Start with the defects and assertion corrections tracked in issue #10, then read .github/workflows/ci.yml and the existing pytest configuration. Run python -m pytest -q tests/test_core.py after installing dependencies and pytest. Done means the corrected tests pass in the Windows/Ubuntu workflow, coverage tooling reports its measured scope, and the broader integration and functional work is tracked separately.
