To determine the minimum quantity of test cases that will give 100% statement coverage, we need to ensure that each executable statement in the code is executed at least once. Let's analyze the code step by step to identify the necessary paths:

Valid account number and active account:

Crediting money to the account.

Old balance < zero, new balance >= zero (overdraft cleared).

VIP customer: message sent by email.

Valid account number and active account:

Crediting money to the account.

Old balance < zero, new balance < zero (account overdrawn).

Non-VIP customer.

Valid account number and active account:

Crediting money to the account.

Old balance >= zero.

VIP customer: message sent by email.

Valid account number but inactive account:

Set message "A/c inactive".

Send message by email to supervisor.

Invalid account number:

Add to the count of invalid inputs.

Considering these scenarios, we can see that the minimum number of test cases to cover all statements is three:

Path with a valid, active account, old balance < zero, new balance >= zero, and VIP customer.

Path with a valid, active account, old balance >= zero, and non-VIP customer.

Path with an inactive account or invalid account number.

Therefore, the correct answer is D. 3.

When purchasing a simulator for performance testing, considerations should include:

Time to test the tool – How long it will take to validate the simulator itself.

Cost of hiring specialists – The financial aspect of requiring specialized knowledge to operate or customize the simulator.

Method and time to upgrade and retest the tool as the software changes – How the simulator can be kept up-to-date with the software it is meant to simulate and the effort involved in retesting it after updates.

These points focus on practical and economic aspects of using a simulator in testing environments.

To achieve 100% decision coverage, we need to ensure that every decision (if statement) in the code has been tested for both true and false outcomes. Let's analyze the code and count the decisions:

IF (Room_price > 200)

IF (Loyalty_level = Platinum) inside Room_price > 200

ELSE within the same decision above

IF (Loyalty_level = Gold) inside the ELSE of decision 2

IF (Room_price > 150)

IF (Loyalty_level = Platinum) inside Room_price > 150

ELSE within the same decision above

IF (Discount_factor < 100%)

To cover all these decisions, we need test cases for each possible combination:

Room_price > 200 and Loyalty_level = Platinum.

Room_price > 200 and Loyalty_level = Gold.

Room_price > 200 and Loyalty_level not Platinum or Gold.

Room_price <= 200 and Room_price > 150, and Loyalty_level = Platinum.

Room_price <= 200 and Room_price > 150, and Loyalty_level not Platinum.

Room_price <= 150.

From these scenarios, we can see that the minimum number of test cases required to achieve 100% decision coverage is four:

Test with Room_price > 200 and Loyalty_level = Platinum (tests decision 1 true, 2 true, and 8 true).

Test with Room_price > 200 and Loyalty_level = Gold (tests decision 1 true, 2 false, 4 true, and 8 true).

Test with Room_price > 200 and Loyalty_level not Platinum or Gold (tests decision 1 true, 2 false, 4 false, and 8 true).

Test with Room_price <= 200 and Room_price > 150, and Loyalty_level = Platinum (tests decision 1 false, 5 true, 6 true, and 8 true).

Test with Room_price <= 200 and Room_price > 150, and Loyalty_level not Platinum (tests decision 1 false, 5 true, 6 false, and 8 true).

Test with Room_price <= 150 (tests decision 1 false, 5 false, and 8 false).

Given that these six cases test all branches, four test cases are required to ensure that all decisions are covered at least once.

Therefore, the correct answer is A. 4.
