CTAL-TTA Exam Dumps : Certified Tester Advanced Level Technical Test Analyst

A Technical Test Analyst during a product risk analysis would consider the complexity of new technology as a generic risk factor. Complex new technology can introduce uncertainties and potential issues that may not be well-understood, which can increase the risk of defects. Frequency of use, visibility of failure, and high change rate of business requirements are also valid considerations, but they are more specific to particular scenarios or aspects of the product rather than the generic technological complexity which is always a concern regardless of the context.

Installability testing is usually conducted during the System Testing stage of the SDLC. It typically includes testing the installation process of the software to verify that it installs correctly across various systems and configurations. This type of testing often overlaps with functionality testing to ensure all functions are available post-installation, and usability testing to ensure that the installation process is intuitive and user-friendly.

Explanation: System testing encompasses a broad spectrum of testing practices intended to validate the software in its entirety, ensuring it meets the specified requirements and is ready for operation.

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.
