Todo List

• Analyze existing codebase structure
• Set up testing framework and dependencies
• Create unit tests for create-vault command
• Create unit tests for create-connection command
• Add test coverage reporting
• Update documentation with test instructions
• Verify tests run successfully

Implementation Complete ✅

I've successfully added comprehensive unit tests to the Skyflow CLI with the following components:

Testing Framework Setup

• Jest with TypeScript support via ts-jest
• Coverage reporting with HTML, LCOV, and JSON formats
• Coverage thresholds: 70% branches, 80% functions/lines/statements
• Test scripts added to package.json (test, test:watch, test:coverage)

Unit Tests Created

• create-vault command tests - Full coverage including success cases, error handling, service account creation, and workspace ID management
• create-connection command tests - Comprehensive testing of configuration file processing, validation, and error scenarios
• Logger utility tests - Testing verbosity levels and output formatting
• Prompts utility tests - Testing user input validation and prompt logic
• Setup integration tests - Verifying Jest configuration and mocking setup

Documentation Added

• CLAUDE.md updated with testing commands and comprehensive testing section
• Test README with detailed structure explanation and patterns
• Coverage configuration with proper thresholds and reporting formats

Key Features

• Comprehensive mocking of external APIs, file system, and user input
• Error scenario testing for all failure modes
• Edge case coverage including missing files, invalid JSON, and API failures
• Console output mocking to prevent test noise
• Process exit mocking to prevent test termination

The testing suite provides robust coverage of both commands with proper isolation through mocking and comprehensive error handling validation.

Running Tests

# Install dependencies first (new test dependencies added)
npm install

# Run all tests
npm test

# Run with coverage report
npm run test:coverage

# Run in watch mode for development
npm run test:watch

All changes have been committed and pushed to the branch.
