🤖 QTEST-CLI - AI Test Generator

AI-powered automated test generation for JavaScript/TypeScript projects using advanced code analysis and intelligent test creation.

🚀 What It Does

QTest CLI is an intelligent test generation tool that:

• 🧠 Analyzes your code using advanced static analysis
• 🤖 Generates comprehensive tests using AI (OpenAI/Gemini via Cline CLI)
• 📊 Detects project types (React, Vue, Node.js, Express, etc.)
• 🎯 Supports multiple frameworks (Jest, Vitest, Mocha)
• 🔄 Watches for changes and auto-regenerates tests
• 📈 Calculates code complexity for better test coverage
• 🌐 Provides fallback templates when AI is unavailable

📦 Installation

Global Installation (Recommended)

npm install -g qtest-cli

Verify Installation

qtest-cli --version

🛠️ Prerequisites

1. Node.js >= 20.0.0

⚡ Quick Start

# Initialize configuration
qtest-cli init

# Generate tests for current directory
qtest-cli analyze .

# Generate tests for specific file
qtest-cli analyze ./src/utils.js

# Watch for changes and auto-generate
qtest-cli watch ./src

📖 Commands

| Command | Description | Options | |---------|-------------|---------| | qtest-cli init | Initialize configuration | - | | qtest-cli analyze [path] | Analyze and generate tests | -f, --framework -o, --output | | qtest-cli watch [path] | Watch for changes | -f, --framework | | qtest-cli --help | Show help | - | | qtest-cli --version | Show version | - |

Command Options

Usage Examples

Basic Analysis

# Analyze current directory with Jest
qtest-cli analyze .

# Use Vitest framework
qtest-cli analyze . --framework vitest

# Custom output directory
qtest-cli analyze ./src --output ./my-tests

Watch Mode

# Watch for changes in src directory
qtest-cli watch ./src

# Watch with Mocha framework
qtest-cli watch ./src --framework mocha

Project Types Detected

• ✅ React Applications - Generates component tests with @testing-library/react
• ✅ Vue.js Projects - Vue component testing
• ✅ Node.js APIs - Express route testing with request mocking
• ✅ TypeScript Projects - Full TypeScript support
• ✅ Next.js Apps - Page and API route testing
• ✅ Vanilla JavaScript - Pure function testing

🔧 Configuration

Run qtest-cli init to create .ai-test-suite.json:

{
  "framework": "jest",
  "outputDir": "./tests",
  "filePatterns": ["**/*.js", "**/*.ts", "**/*.jsx", "**/*.tsx"],
  "excludePatterns": [
    "node_modules/**",
    "dist/**", 
    "build/**",
    "**/*.test.*"
  ]
}

📊 Example Output

Input File (utils.js)

function add(a, b) {
  return a + b;
}

function divide(a, b) {
  if (b === 0) {
    throw new Error('Division by zero');
  }
  return a / b;
}

module.exports = { add, divide };

Generated Test (utils.test.js)

const { add, divide } = require('./utils');

describe('utils', () => {
  describe('add', () => {
    test('should add two numbers correctly', () => {
      expect(add(2, 3)).toBe(5);
      expect(add(0, 0)).toBe(0);
      expect(add(-1, 1)).toBe(0);
    });

    test('should handle negative numbers', () => {
      expect(add(-5, -3)).toBe(-8);
    });
  });

  describe('divide', () => {
    test('should divide two numbers correctly', () => {
      expect(divide(10, 2)).toBe(5);
      expect(divide(9, 3)).toBe(3);
    });

    test('should throw error for division by zero', () => {
      expect(() => divide(10, 0)).toThrow('Division by zero');
    });

    test('should handle decimal division', () => {
      expect(divide(7, 2)).toBe(3.5);
    });
  });
});
