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.

For an online dating service experiencing heavy usage, particularly important in the architecture review checklist is to verify the process isolation between OLTP (Online Transaction Processing) and OLAP (Online Analytical Processing). This ensures that heavy reporting activities do not impact the real-time transactional processes that affect user experience, such as query response times. Ensuring process isolation allows both systems to operate efficiently without interference, critical during peak usage times .

The statement "Test suite coverage can be increased without the need for refactoring" is accurate because test suite coverage refers to the extent to which the test cases cover the software under test. This coverage can be enhanced by adding new tests that address areas not previously covered, without necessarily modifying the existing test structures or setups. Refactoring is often related to improving the internal design of the tests for better maintainability or performance but does not inherently affect the coverage directly .
