Software Validation and Testing

Question 1: Suppose that we test a discount system in some e-shop. The system can send a loyalty card to a client and admit a discount of 0% (no discount), 5%, or 10% according to the following rules:

• No discount is the default discount option.
• A nonregistered user has 0% discount by definition.
• If a registered user spent more than $1000 in the previous shopping sessions, and there were 19 or less shopping sessions, admit 5% discount.

• If a registered user spent more than $1000 in the previous shopping sessions and there were at least 20 shopping sessions, admit 10% discount.
• A loyalty card is sent only to registered customers who spent more than $1000 or had at least 20 shopping sessions.

• Give the complete decision table
• Design test cases for the requirements
• Write a java code for the given requirement
• Write a Junit test and use the test cases.
• Report the output of the test. Report if there are any defects and fixes.
