Exercise 2
Feature: Discount for returning customers
We want to reward returning customers with an extra discount of 10%
on subsequent orders, because we believe that it will motivate them to buy
more books.
Scenario: Informing about the discount
Given there is a buyer
And he already bought books from us
When he adds a book to the shopping cart
And the cart is empty
Then he is informed about that 10% discount will be applied on this order
Scenario: Applying the discount
Given there is a buyer
And he already bought books from us
And he added 3 books worth 10 EUR to the shopping cart
And the VAT to be paid over the 3 books is 2.10 EUR
And the shipping is 5 EUR
When the buyer places the order
Then the total he will be charged is 16.10 EUR
