# Integration Testing Suite\n\n**Version**: 1.0.0\n**Status**: ✅ Complete\n**Test Coverage**: 140 tests across 4 modes, 15+ services\n\n---\n\n## Overview\n\nThis directory contains the comprehensive integration testing suite for the provisioning platform. Tests validate all four execution modes (solo, multi-user, CI/CD, enterprise) with full service integration, workflow testing, and end-to-end scenarios.\n\n**Key Features**:\n\n- ✅ **4 Execution Modes**: Solo, Multi-User, CI/CD, Enterprise\n- ✅ **15+ Services**: Orchestrator, CoreDNS, Gitea, OCI registries, PostgreSQL, Prometheus, etc.\n- ✅ **OrbStack Integration**: Deployable to isolated OrbStack machine\n- ✅ **Parallel Execution**: Run tests in parallel for speed\n- ✅ **Multiple Report Formats**: JUnit XML, HTML, JSON\n- ✅ **Automatic Cleanup**: Resources cleaned up after tests\n\n---\n\n## Quick Start\n\n### 1.

Writing New Tests\n\n1. **Choose appropriate directory**: `modes/`, `services/`, `workflows/`, `e2e/`, `performance/`, `security/`\n2. **Follow naming convention**: `test_<feature>_<category>.nu`\n3. **Use test helpers**: Import from `framework/test_helpers.nu`\n4. **Add assertions**: Use `assert-*` helpers\n5. **Cleanup resources**: Always cleanup, even on failure\n6. **Update coverage**: Add test to TEST_COVERAGE.md\n\n### Example Test\n\n```\nuse std log\nuse ../framework/test_helpers.nu *\n\ndef test-my-feature [test_config: record] {\n    run-test "my-feature-test" {\n        log info "Testing my feature..."\n\n        # Setup\n        let resource = create-test-resource\n\n        # Test\n        let result = perform-operation $resource\n\n        # Assert\n        assert-eq $result.status "success"\n\n        # Cleanup\n        cleanup-test-resource $resource\n\n        log info "✓ My feature works"\n    }\n}\n```\n\n---\n\n## Metrics\n\n### Test Suite Statistics\n\n-
