Context Pods

# Context-Pods Test Infrastructure This directory contains the comprehensive testing infrastructure for Context-Pods, implementing **Checkpoint 0** of the checkpoint-based testing strategy defined in [Issue #23](https://github.com/conorluddy/ContextPods/issues/23). ## 🎯 Checkpoint-Based Testing Strategy Context-Pods follows an incremental testing approach with 11 checkpoints designed to achieve 85%+ test coverage through 49 carefully planned tests. ### Checkpoint Status: - ✅ **Checkpoint 0**: Test Infrastructure Foundation (COMPLETED) - 🚀 **Next**: Checkpoint 1.1 - Template Engine Core Tests ## 📁 Directory Structure ``` tests/ ├── README.md # This documentation ├── setup.ts # Global test setup and environment ├── fixtures/ # Shared test data and templates │ └── templates/ # Template fixtures for testing │ ├── basic-ts/ # TypeScript MCP server template │ └── basic-python/ # Python MCP server template └── utils/ # Test utilities and helpers ├── mocks.ts # Mock implementations ├── builders.ts # Test data builders └── helpers.ts # Test helper functions ``` ## 🛠️ Test Utilities ### Mocks (`utils/mocks.ts`) - **`createMockFileSystem()`** - memfs-based filesystem mocking - **`createMockMCPClient()`** - MCP protocol client mocking - **`createMockMCPServer()`** - MCP protocol server mocking - **`createMockDatabase()`** - SQLite database mocking - **`createMockLogger()`** - Logger interface mocking ### Builders (`utils/builders.ts`) - **`templateBuilder`** - Template metadata builders - **`metadataBuilder`** - Generic metadata builders - **`variableBuilder`** - Template variable builders - **`serverConfigBuilder`** - Server configuration builders ### Helpers (`utils/helpers.ts`) - **`createTempDir()`** - Temporary directory creation - **`startTestServer()`** - Test MCP server management - **`waitFor()`** - Async condition waiting - **`createMockTemplate()`** - Template fixture creation - **`captureConsole()`** - Console output capture - **`withTimeout()`** - Timeout wrapper for async operations ## 🧪 Test Fixtures ### TypeScript Template (`fixtures/templates/basic-ts/`) Complete MCP server template with: - `metadata.json` - Template configuration - `package.json.mustache` - Package definition with variables - `src/index.ts.mustache` - Working MCP server implementation ### Python Template (`fixtures/templates/basic-python/`) Complete MCP server template with: - `metadata.json` - Template configuration - `main.py.mustache` - Working MCP server implementation - `requirements.txt.mustache` - Python dependencies ## ⚙️ Configuration ### Root Configuration (`/vitest.config.ts`) - **Coverage**: v8 provider with text, JSON, HTML, LCOV reports - **Environment**: Node.js testing environment - **Aliases**: Package path aliases for imports - **Setup**: Global test setup file - **Thresholds**: Coverage thresholds (starts at 0%, increases per checkpoint) ### Package-Specific Configurations Each package has its own `vitest.config.ts` that extends the root configuration: - `packages/core/vitest.config.ts` - `packages/server/vitest.config.ts` - `packages/cli/vitest.config.ts` ## 🚀 Usage ### Running Tests ```bash # Run all tests npm test # Run tests for specific package cd packages/core && npm test # Run tests with coverage npm test -- --coverage # Run tests in watch mode npm test -- --watch ``` ### Using Test Utilities ```typescript import { templateBuilder, createMockFileSystem } from '../utils/builders.js'; import { createMockFileSystem } from '../utils/mocks.js'; describe('Template Processing', () => { it('should process template variables', () => { // Create test data const template = templateBuilder.basic({ name: 'test-server', variables: [ /* ... */ ], }); // Mock filesystem const { fs, reset } = createMockFileSystem(); // Test implementation // ... // Cleanup reset(); }); }); ``` ## 🎯 Next Steps With Checkpoint 0 complete, the infrastructure is ready for: 1. **Checkpoint 1.1**: Template Engine Core Tests (5 tests) - Variable substitution testing - Nested object handling - Missing variable handling - Content preservation validation - Array iteration support 2. **Checkpoint 1.2**: Template Engine File Operations (5 tests) - Output directory creation - File structure preservation - Mustache file processing - Permission preservation - Error handling 3. **Checkpoint 3.1**: E2E Basic Validation (3 tests) - TypeScript server generation - Python server generation - MCP protocol validation ## 📊 Coverage Goals - **Current**: 0% (infrastructure only) - **Target**: 85%+ across 11 checkpoints - **Strategy**: Incremental coverage growth with each checkpoint - **Validation**: E2E tests ensure generated servers actually work ## 🔗 Related Documentation - [Issue #23: Checkpoint-Based Testing Implementation](https://github.com/conorluddy/ContextPods/issues/23) - [Project README](../README.md) - [Architecture Documentation](../docs/ARCHITECTURE.md) --- **Status**: ✅ Checkpoint 0 Complete - Ready for Template Engine Testing The test infrastructure provides a comprehensive foundation for systematic testing of the Context-Pods MCP development toolkit. All utilities, mocks, and fixtures are production-ready and designed to support the full 11-checkpoint testing journey.
