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

An effective review preparation by a Technical Test Analyst includes ensuring that participants are well-prepared and that they spend enough time on preparation, which can be managed by checking the rate (option A). The use of review checklists (option C) and providing review training (option D) are also methods that contribute to more effective review preparation. However, managing the logging rate (option B), or the number of defects logged per minute during the meeting, is not related to the preparation phase but rather to the defect detection and logging phase during the actual review meeting. It is not a preparation activity but a review execution activity.

Upon analyzing the control flow diagram provided, there are four distinct paths through the program, considering the flow between decision points and actions. Each path represents a unique sequence of execution through the system logic, dictated by the decision outcomes at various points. This information is critical for ensuring comprehensive testing coverage, as each path may expose different behaviors or outcomes in the application​​.

In a critical system that handles financial transactions with complex logic, ensuring thorough testing coverage is crucial. Here’s an analysis of the options:

A. Multiple Condition coverage: This provides the highest level of coverage by testing all possible combinations of conditions. However, it can be very time-consuming and is often impractical for complex systems due to the sheer number of test cases required.

B. MC/DC coverage: Modified Condition/Decision Coverage is a compromise between multiple condition coverage and decision coverage. It ensures that each condition within a decision has been shown to independently affect the outcome of that decision. This level of coverage is often required in safety-critical systems because it provides thorough testing without the excessive test case count of multiple condition coverage.

C. Decision coverage: This ensures that every decision (if statement) has been executed in both true and false directions. While useful, it may not be sufficient for complex systems where the interactions between conditions are critical.

D. Statement coverage: This ensures that every executable statement in the code has been executed. It is the most basic level of coverage and is generally not sufficient for complex systems, especially those that are critical to an organization’s finances.

Given the critical nature of the system and the need for a balance between thoroughness and practicality, the best option is B. MC/DC coverage. This ensures a high level of coverage that is more practical than multiple condition coverage while providing more assurance than decision or statement coverage.

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.

Fault seeding and fault injection tools are used intentionally to introduce defects into a system or software to test the robustness of the test suite. This method helps in validating the effectiveness of the test processes and configurations by ensuring that the tests are capable of detecting and isolating inserted faults. It is a technique used to measure the quality of testing rather than debugging or performance compliance, which relates directly to the fundamental purpose of enhancing test coverage and the detection capability of the test suite .
