What is the minimum quantity of test cases that will give 100% statement coverage?
Consider the following specification:

If you are flying with an economy ticket, there is a possibility that you may get upgraded to business class, especially if you hold a gold card in the airline’s frequent flier program. If you don’t hold a gold card, there is a possibility that you will get ‘bumped’ off the flight if it is full when you check in late.
This is shown in the control flow graph below. Note that each box (i.e., statement, decision) has been numbered.
Three tests have been run:
Test 1: Gold card holder who gets upgraded to business class
Test 2: Non-gold card holder who stays in economy
Test 3: A person who is bumped from the flight
What is the level of decision coverage achieved by these three tests?
How many test cases need to be designed to achieve 100% decision coverage in the following piece of pseudo-code which applies discount rates to hotel room bookings?
Read (Loyalty_level)
Read (Room_price)
IF (Room_price > 200)
IF (Loyalty_level = Platinum)
Discount_factor = 80%
ELSE
IF (Loyalty_level = Gold)
Discount_factor = 85%
ELSE
Discount_factor = 95%
ENDIF
ENDIF
ELSE
IF (Room_price > 150)
IF (Loyalty_level = Platinum)
Discount_factor = 85%
ELSE
Discount_factor = 95%
ENDIF
ELSE
Discount_factor = 100%
ENDIF
ENDIF
Room_price = Room_price * Discount_factor
IF (Discount_factor < 100%)
Show message "Congratulations - you have received a discount!"
