Gateway Testing

The DeployStack Gateway includes testing infrastructure for ensuring reliability and quality of the CLI application.

Test Commands

Unit Tests

npm run test:unit

Currently displays a placeholder message as tests are not yet implemented.

Linting

npm run lint

Runs ESLint with automatic fixing of common issues. Essential for maintaining code quality.

Build Verification

npm run build

Compiles TypeScript to JavaScript and verifies the build process.

Development Workflow

Local Development

npm run dev

Starts the gateway in development mode with hot reload using ts-node-dev.

Manual Testing

npm run link

Links the local gateway for testing CLI commands globally.

After linking, test commands directly:

deploystack version
deploystack status
deploystack --help

Release Testing

Pre-release Checks

npm run release

Runs linting checks before creating a release through release-it.

CI/CD Testing

The GitHub Actions workflow automatically runs:

• Build verification
• Linting checks
• Unit tests (when implemented)

Testing Strategy

CLI-Specific Testing

• Command validation: Ensure all commands parse correctly
• Output formatting: Verify chalk styling and user messages
• Error handling: Test failure scenarios and exit codes
• Cross-platform: Validate behavior on Windows, macOS, and Linux

Integration Points

• Authentication flows: Test login/logout workflows
• Configuration management: Verify config file operations
• Process management: Test MCP server spawning and cleanup
• Proxy functionality: Validate HTTP proxy routing

Future Testing Implementation

The gateway will include comprehensive testing using:

• vitest for unit testing
• supertest for HTTP endpoint testing
• msw for API mocking
• Cross-platform testing in CI/CD

Development Tips

Quick Validation

# Check command structure
deploystack --help

# Verify version info
deploystack version

# Test error handling
deploystack invalid-command

Build and Test Cycle

npm run lint    # Fix code style issues
npm run build   # Verify compilation
npm run link    # Test locally

This testing approach ensures the gateway maintains high quality while remaining focused on the essential CLI functionality.
