In this homework you will be given a simple store program, in which you can

create products and add them to your cart, then calculate shipping cost, plus

discounts. Using Junit and EclEmma, you will need to perform Whitebox testing.

You need to do the following:

$$ Install eclipse for java and EclEmma plugin, then import the provided code $($SimpleStorehw$3.$zip$).$

$$ Answer the following questions using JUnit and EclEmma to achieve $100\%$ coverage:

o In class Product.java, test the following functions using Statement and Decision

coverage, knowing that:

$$ setName: a valid name consists of alphabetical characters with lengths

between $1$ and $10.$ In case of invalid names, the function will throw

IllegalArgumentException.

$$ setPrice: a valid price is a decimal value between $0\mathrm{.}01$ and $1000.$ In case

of invalid prices, the function will throw IllegalArgumentException.

o In class Store.java, test the following function using condition$-$decision

coverage, knowing that:

$$ computeShippingCost: This function calculates the shipping cost based

on the total price in cart. The function returns the following:

$$ cart is empty: throw IllegalStateException

$$ total $<100$: shipping cost $20$

$100<=$ total $<500$: shipping cost $10$

$$ total $>=500$: shipping is free

o In class Store.java, test the following function using multiple$-$condition

coverage, knowing that:

$$ calculateDiscount: the function computes the total percentage of the

discount a user will get as follows: The user will get a discount of $5\%$ if the

total price of cart is greater than $100$ and less than or equal to $500.$ A

discount of $7\%$ is given if the total is over $500.$ If the user is a new customer,

then she will receive an extra $10\%$ discount. Noting that discounts can be added

up$.$

o In class Cart.java, test the following function using loop coverage, knowing that:

$$ total: the function will compute the total cost of items in cart and return

the total as decimal value. In case the cart was empty the function will

return $0.$

Note: You are expected to achieve $100\%$ coverage in testing all the functions above. Your

code will be graded accordingly.

$$ Submit your testcases in one test class on the elearning.

Important notes:

$$ The Driver class demonstrates how to use Store Class.

$$ Make sure to keep each testcase in a sperate test function.

$$ If your code doesn$$t compile you will get zero.

$$ Make sure to use Junit$4$ and eclipse studio.
