Implementation for the katas
-
I have implemented the kata 16 that and added the tests in order to verify the expected result.
-
I think that there are many ways to implement those rules but the thing that needs to be kept in mind is the SOLID principles. Specially the Open/Close principle in order to reduce possible impact on the changes.
Things that should be improved with a bit more time:
- Covers with unit tests the whole application.
- Make clear the responsibilities between the payment service and the order service. I think that it may be unclear where are the boundaries with OrderService and PaymentService.
- Improve the design of the Product models but in a way that respects the substitution principle.
