The service is presented using a variant of the MVC architecture applying different tools that allow easy testing of the challenge. For this we use an in-memory H2 database and documentation using Swagger. We opted for the use of Java 17 as a test implementation.

We used java version 17 using the following dependencies:

• Spring Boot 3.0.4
• Apache Maven 3.8.7
• H2 Database
• MyBatis
• Lombok
• Swagger

1. Clone the repository
2. Build the project with mvn command: mvn clean install
3. Run the project with mvn command: mvn spring-boot:run
4. You can test the endpoints using the swagger interface go to the following url: http://localhost:8080/swagger-ui/index.html#/

• Run the tests with mvn command: mvn test

Cart is an online shopping cart concept commonly used in ecommerce services, in which we store our list of desired products, therefore we use the following endpoints to manipulate the cart.

Every cart has products for purchase, these products are listed and well labeled according to the catalog that has our platform.

{
  "products": [
    {
      "id": 1,
      "description": "Product 1",
      "price": 1
    }
  ]
}

curl -X 'GET' \
  'http://localhost:8080/product' \
  -H 'accept: application/hal+json'

{
  "description": "Product 2",
  "price": 10.3
}

{
  "id": 2
}

curl -X 'POST' \
  'http://localhost:8080/product' \
  -H 'accept: application/hal+json' \
  -H 'Content-Type: application/json' \
  -d '{
  "description": "Product 2",
  "price": 10.3
}'

{
  "id": 1,
  "description": "Product 1",
  "price": 1
}

curl -X 'GET' \
  'http://localhost:8080/product/1' \
  -H 'accept: application/hal+json'

OpenAPIv3 was used to launch our documentation.

A task is set every 10 minutes to check that no car has expired, otherwise it deletes it. This can be found in the JobConfiguration.java file.

Nine tests were performed and were satisfactory.
