Write a program driven by unit tests that can price a basket of goods taking into account some special offers. The goods that can be purchased, together with their normal prices are:
- Soup – 65p per tin
- Bread – 80p per loaf
- Milk – £1.30 per bottle
- Apples – £1.00 per bag
Current special offers
- Apples have a 10% discount off their normal price this week
- Buy 2 tins of soup and get a loaf of bread for half price
The program should accept a list of items in the basket and output the subtotal, the special offer discounts and the final price.
Input should be via the command line in the form PriceBasket item1 item2 item3 ...
- Configuration file includes inputs for prices, discounts and log level.
- You can add new items to application.conf under resources directory.
- Price item =>
{ item: {name = ""}, cost = ""}. Cost format : {[X]p} or {£[X]} - Discount item =>
item: {name = "" , count = 0 }, discounted: {name = "" , count = 0 }, ratio = 1, message = ""},{name = "" , count = 0 }=> Item that you should buy. count: how many you should buy{name = "" , count = 0 }=> Item which will be discounted. count: how many of them will be used for discount
- log-level is INFO as default.
prices:
[
{ item: {name = "Soup"}, cost = "65p"},
{ item: {name = "Bread"}, cost = "80p"},
{ item: {name = "Milk" }, cost = "£1.30"},
{ item: {name = "Apples"}, cost = "£1.0"}
]
discounts:
[
{ item: {name = "Apples" , count = 1 }, discounted: {name = "Apples" , count = 1 }, ratio = 0.1, message = "Apples 10% off!"},
{ item: {name = "Soup" , count = 2 }, discounted: {name = "Bread" , count = 1 }, ratio = 0.5, message = "Bread 50% off!"}
]
log-level: "OFF"
- P.S : If there are discounts matching for same item, discount which is highest will be used.
