HPE Software Engineer Job Simulation

This repository contains my completed work for Hewlett Packard Software Engineer Training.
The project focuses on building and testing a RESTful Employee Management web service with Java Spring Boot, along with a proposal for deployment on the HPE GreenLake private cloud platform.

Overview

During this program, I designed and implemented a REST API for managing employee records. The system supports CRUD operations, is backed by unit and integration tests, and includes a professional proposal for deployment to cloud infrastructure.

Key Components

1. Employee Management REST API

• Spring Boot Application implementing a RESTful service.
• Core features:
  • GET /employees → retrieve all employees
  • POST /employees → add a new employee
  • (Proposal includes PUT and DELETE for updates and removals)
• Data is represented via an Employee entity with fields:
  • employee_id
  • first_name
  • last_name
  • email
  • title

2. Service Layer

• EmployeeManager.java manages an in-memory list of employees and exposes methods to retrieve and add employees.
• Employees.java is a wrapper class for holding a list of Employee objects.

3. Testing

• Comprehensive JUnit + MockMvc tests in RestServiceApplicationTests.java:
  • testGetEmployees() validates retrieval of employee data.
  • testAddEmployee() verifies employee creation with proper HTTP status codes and headers.

4. Cloud Deployment Proposal

• Employee Management RESTful Web Service Proposal.pdf
• Outlines design for deployment on HPE GreenLake with:
  • Persistent storage in a relational database (MySQL/PostgreSQL).
  • Full CRUD support (GET, POST, PUT, DELETE).
  • Authentication and security measures.
  • Error handling for 400, 404, and 500 cases.
