I have developed the test following DDD and hexagonal architecture principles. The Application only uses InMemory repositories with prefilled data, so the data is not persisted through requests, but a different implementation can be developed and added with minimal changes to the existing code.

To have the development environment set up with docker:

cd docker
docker-compose up -d
docker-compose exec php composer install

Aftwerwards the test suite can be run using this command

docker-compose exec php php bin/phpunit

The application listens on port 80 by default. It can be changed in docker/docker-compose.yml.

To add a product to the current user's cart: PUT /cart/product/add

To retrieve the products in the current user's cart: GET /cart/product

In order to be able to retrieve the current user the Authorization HTTP header has to contain a bearer token. There is an accessible user with the "randomgeneratedtoken" token so it is easier to play with the API.

Example cURL calls would be:

curl -X GET \
  http://localhost/cart/product \
  -H 'Authorization: Bearer: randomgeneratedtoken' \
  -H 'Content-Type: application/json'

curl -X PUT \
  http://localhost/cart/product/add \
  -H 'Authorization: Bearer: randomgeneratedtoken' \
  -H 'Content-Type: application/json' \
  -H 'content-length: 19' \
  -d '{
    "productId": 1
}'

At first I developed a session based authentication but I scraped it because being a REST API using session based authentication made no sense. So I developed a simple token based authentication.

The docker images I developed are focused on development and for the testers. Another docker deployment images should be created for the deployment of this app.
