## Purpose
Comprehensive unit tests for CLI setup functionality, validating command creation, configuration, and execution behavior of both stdio and SSE transport modes.
## Test Structure
### Core CLI Tests (L6-19)
- **createCLI test (L7-18)**: Validates CLI command instance creation with name, description, and version configuration
### Stdio Command Tests (L21-82)
- **Configuration validation (L22-47)**: Verifies stdio command setup with correct options:
- `--log-level/-l` option with default 'info' (L37-43)
- `--log-file` option for file logging (L38, L45-46)
- **Execution tests (L49-81)**: Tests command handler invocation with custom and default log levels
### SSE Command Tests (L84-153)
- **Configuration validation (L85-116)**: Verifies SSE command setup with three options:
- `--port/-p` option with default '3001' (L100, L104-107)
- `--log-level/-l` option with default 'info' (L101, L109-112)
- `--log-file` option for file logging (L102, L114-115)
- **Execution tests (L118-152)**: Tests command handler invocation with custom and default values
### Integration Tests (L155-170)
- **Default command behavior (L156-169)**: Validates stdio as default command when no subcommand specified
## Key Dependencies
- **vitest**: Testing framework with mocking capabilities
- **commander**: Command-line interface library being tested
- **CLI setup module**: Imports `createCLI`, `setupStdioCommand`, `setupSSECommand`, and handler types
## Testing Patterns
- Mock handlers using `vi.fn()` with async resolution
- Command parsing via `program.parseAsync()` with simulated argv
- Option validation through command introspection
- Handler verification using `expect.objectContaining()` for partial matching
## Transport Modes Tested
- **Stdio**: Standard input/output transport with logging configuration
- **SSE**: Server-Sent Events transport with port and logging configuration
