# Testing Suite Implementation - Complete

## Overview

This PR adds a comprehensive testing framework for Bash Buddy v2.1.0 with automated testing for all operating modes, performance benchmarking, and detailed reporting capabilities.

## What's Added

### 🧪 Test Framework (`tests/test-framework.sh`)
- Modular testing utilities and helper functions
- Performance timing and benchmarking
- JSON, Markdown, and HTML report generation
- Color-coded output for readability
- Test statistics tracking

### 📝 Test Suites

#### 1. Non-Interactive Mode Tests (`tests/test-all-modes.sh`)
**45+ test cases covering:**
- Help & informational modes (`--help`, `--list`)
