Welcome to the Capstone Project of the Groovy Programming Course! This project is designed to consolidate and apply the knowledge you have gained throughout the course. By the end of this project, you will have a comprehensive understanding of how to develop a full-fledged application using Groovy, incorporating various features and best practices.

The main objectives of this capstone project are:

1. Application Development: Develop a complete application using Groovy, from setting up the environment to deployment.
2. Feature Integration: Integrate various Groovy features such as collections, closures, object-oriented programming, and advanced features like metaprogramming and DSLs.
3. Practical Experience: Gain hands-on experience with Groovy's ecosystem and tools, including Gradle, Spock, and Grails.
4. Testing and Debugging: Implement unit tests, mocking, and debugging techniques to ensure the reliability and maintainability of your application.
5. Best Practices: Apply best practices in code style, performance optimization, security, and concurrency.

In this project, you will develop a Task Management System. This system will allow users to create, update, delete, and view tasks. The application will also support user authentication and authorization, ensuring that only authenticated users can manage tasks.

1. User Management:

   • User registration and login.
   • Password encryption and secure authentication.
   • Role-based access control.

2. Task Management:

   • Create, read, update, and delete tasks.
   • Assign tasks to users.
   • Set task priorities and deadlines.
   • Mark tasks as completed.

3. Data Persistence:

   • Use a database to store user and task information.
   • Implement CRUD operations for database interaction.

4. Web Interface:

   • Develop a web interface using Groovy and Grails.
   • Provide a user-friendly interface for managing tasks.

5. Testing and Debugging:

   • Write unit tests using the Spock framework.
   • Implement mocking and stubbing for testing.
   • Debug the application to fix issues and improve performance.

The project will be divided into the following phases:

1. Project Setup:

   • Set up the development environment.
   • Initialize the project using Gradle.
   • Configure the database and other dependencies.

2. Implementation:

   • Develop the user management module.
   • Implement the task management module.
   • Integrate the web interface using Grails.
   • Ensure data persistence with database integration.

3. Testing and Debugging:

   • Write and execute unit tests.
   • Perform integration testing.
   • Debug and optimize the application.

4. Deployment:

   • Prepare the application for deployment.
   • Deploy the application to a web server.
   • Ensure the application is running smoothly in the production environment.

By the end of this project, you should deliver the following:

1. Source Code: The complete source code of the Task Management System, organized and documented.
2. Documentation: Detailed documentation explaining the architecture, design decisions, and usage of the application.
3. Test Cases: A comprehensive suite of test cases covering various aspects of the application.
4. Deployment Guide: Instructions for deploying the application to a web server.

Your project will be evaluated based on the following criteria:

1. Functionality: The application should meet all the specified requirements and features.
2. Code Quality: The code should be well-organized, readable, and follow best practices.
3. Testing: The application should have comprehensive test coverage with passing test cases.
4. Documentation: The documentation should be clear, detailed, and helpful.
5. Deployment: The application should be successfully deployed and accessible.

This capstone project is an excellent opportunity to apply your Groovy programming skills in a real-world scenario. Take your time to plan, implement, and test your application thoroughly. Good luck, and happy coding!
