A Spring Boot REST API for managing tasks with full CRUD operations.

• Database: MySQL
• Database Name: taskdb
• Integration:
  • Used Spring Data JPA to interact with MySQL.
  • The entity class Task is mapped to a database table.
  • Database connection configured in application.properties with JDBC URL, username, and password.
  • Hibernate automatically manages schema updates with spring.jpa.hibernate.ddl-auto=update.

• Java 21 or above installed
• Maven installed
• MySQL server running

1. Create the database (if not already done):

   CREATE DATABASE taskdb;

2. Configure your MySQL credentials in src/main/resources/application.properties:

   spring.datasource.url=jdbc:mysql://localhost:3306/taskdb
   spring.datasource.username=root
   spring.datasource.password=system
   spring.jpa.hibernate.ddl-auto=update

3. Build and run the Spring Boot app:

   ./mvnw spring-boot:run

4. Server will start on: http://localhost:9091 (or the configured port)

You can use tools like Postman, curl, or any HTTP client.

• Create a Task (POST /api/tasks)

  {
    "title": "Finish API Server",
    "description": "Build and test Spring Boot API project",
    "completed": false
  }

• Get All Tasks (GET /api/tasks)

  Response:

  [
    {
      "id": 1,
      "title": "Finish API Server",
      "description": "Build and test Spring Boot API project",
      "completed": false
    }
  ]

• Update a Task (PUT /api/tasks/{id})

  {
    "title": "Finish API Server - Updated",
    "description": "Updated project backend",
    "completed": true
  }

• Delete a Task (DELETE /api/tasks/{id})

• JUnit 5 – For writing unit and integration tests
• Mockito – For mocking dependencies
• MockMvc – For simulating HTTP requests in API tests
• JaCoCo – For generating code coverage reports

To run all tests and generate the code coverage report:

./mvnw clean test

or on Windows:

mvnw.cmd clean test

📂 After running, the coverage report can be found at:
