I want to be clear about the design. It was done with the idea to
apply on a set of line only one promotion. This way promotion does not
accumulate (there is a unique field 'promotion' on sale line).
I think we could maybe change the test to decide line by line if the
promotion applied instead of having a unique test on all lines.
But the decision is to decide how to apply such kind of promotions:
- 15% if quantity of product is greater than 10kg.
- 10% for products of category "Fruits".
So now we have a sale with:
- 5kg of potatoes at 10€/kg
- 5kg of apples at 15€/kg
- 3u of melons at 20€/u
Should the sale be:
A)
- potatoes: 8.5€/kg
- apples: 13.5€/kg
- melons: 18€/u
B)
- potatoes: 8.5€/kg
- apples: 12.75€/kg
- melons: 18€/u
C)
- potatoes: 8.5€/kg
- apples: 12.75€/kg
- melons: 20€/u
For now, we have option C implemented, but maybe we should implement B.
