LocalAI Test Case Generator

Overview

The LocalAI Test Case Generator is a sophisticated web application designed to streamline the software testing process by automatically generating comprehensive test cases using LocalAI's language models. This tool helps developers and QA engineers create thorough test suites by analyzing program descriptions and requirements.

Key Features

1. AI-Powered Test Generation

• Utilizes LocalAI's language models for intelligent test case generation
• Produces structured, JSON-formatted test cases
• Covers multiple testing aspects:
  • Happy path scenarios
  • Edge cases
  • Error conditions
  • Boundary values
  • Performance considerations

2. Comprehensive Test Coverage

Each generated test case includes:

• Detailed description of the test scenario
• Specific input values
• Expected outputs
• Test type categorization
• Priority level assignment

3. User-Friendly Interface

• Clean, modern web interface built with React
• Real-time test case generation
• Interactive chat-like interface for program description input
• Beautifully formatted test case output
• Easy-to-use settings configuration

4. LocalAI Integration

• Flexible server configuration
• Support for multiple LocalAI models
• Persistent settings storage
• Server health checking and validation

Technical Architecture

Frontend

• React.js with TypeScript
• Modern UI components using shadcn/ui
• TanStack Query for efficient data fetching
• Responsive design with Tailwind CSS
• Wouter for lightweight routing

Backend

• Node.js with Express
• PostgreSQL database for message persistence
• Drizzle ORM for type-safe database operations
• RESTful API architecture
• Structured error handling

Data Model

• Settings: Stores LocalAI configuration (server URL and model)
• Messages: Stores conversation history and generated test cases
• Test Cases: Structured JSON format for generated tests

Usage Instructions

1. Configure LocalAI Settings

   • Navigate to the Settings page
   • Enter your LocalAI server URL
   • Select the desired language model
   • Save your configuration

2. Generate Test Cases

   • Go to the main chat interface
   • Enter a description of the program or feature you need tests for
   • Click "Generate" to create test cases
   • Review the generated test cases, which include:
     • Test descriptions
     • Input data
     • Expected outputs
     • Test types
     • Priority levels

3. Review and Export

   • Generated test cases are displayed in an easy-to-read format
   • Test cases are color-coded by priority
   • Each test case shows detailed input/output specifications

Example Output

The system generates test cases in the following format: ```json { "testCases": [ { "description": "Valid user registration with all required fields", "input": { "username": "john_doe", "email": "john@example.com", "password": "SecurePass123" }, "expectedOutput": { "status": "success", "userId": "<generated_id>" }, "type": "happy-path", "priority": 1 } ] } ```

Future Enhancements

• Test case history tracking
• Export functionality for generated tests
• Custom prompt templates for different testing scenarios
• Integration with testing frameworks
• Batch test case generation
• Test case validation and verification

Getting Started

1. Clone the repository
2. Install dependencies: `npm install`
3. Start the development server: `npm run dev`
4. Access the application at `http://localhost:5000\`

Requirements

• Node.js 18+
• PostgreSQL database
