README (THIS IS JUST AN EXCERCISE) DO NOT USE THIS
This README would normally document whatever steps are necessary to get your application up and running.
I used BDD for this and here is the feature file corresponding to the tests PointOfSaleCheckout.feature
Prerequisites
- Java 8 SDK
- Maven 3.0
Run Tests
Run the following command in the project root folder where is located pom.xml
mvn test
Use the API
In order to use the API you need an instance of PointOfSaleFacade
PointOfSaleFacade pointOfSaleFacade = new PointOfSaleFacade();
Add a new product
pointOfSaleFacade.getProductService().add(new Product("A",new BigDecimal(2.00)));
...
Set volume price
pointOfSaleFacade.getProductService().addVolumePrice(new ProductVolumePrice("A",4,new BigDecimal(7.00)));
...
Scan a product
pointOfSaleFacade.getPointOfSaleTerminaService().scan("A");
....
Calculate Total
BigDecimal total = pointOfSaleFacade.getPointOfSaleTerminaService().calculateTotal();
Checkout (Set everything ready for another order)
pointOfSaleFacade.getPointOfSaleTerminaService().checkout();
Full sample
public class Main {
public static void main(String[] args) throws EntryNotFoundException {
PointOfSaleFacade pointOfSaleFacade = new PointOfSaleFacade();
pointOfSaleFacade.getProductService().add(new Product("A",new BigDecimal(2.00)));
pointOfSaleFacade.getProductService().addVolumePrice(new ProductVolumePrice("A",4,new BigDecimal(7.00)));
pointOfSaleFacade.getProductService().add(new Product("B",new BigDecimal(12.00)));
pointOfSaleFacade.getProductService().add(new Product("C",new BigDecimal(1.25)));
pointOfSaleFacade.getProductService().addVolumePrice(new ProductVolumePrice("C",6,new BigDecimal(6.00)));
pointOfSaleFacade.getProductService().add(new Product("D",new BigDecimal(0.15)));
pointOfSaleFacade.getPointOfSaleTerminaService().scan("A");
pointOfSaleFacade.getPointOfSaleTerminaService().scan("B");
pointOfSaleFacade.getPointOfSaleTerminaService().scan("C");
pointOfSaleFacade.getPointOfSaleTerminaService().scan("D");
System.out.println(pointOfSaleFacade.getPointOfSaleTerminaService().calculateTotal());
pointOfSaleFacade.getPointOfSaleTerminaService().checkout();
}
}
