ISTQB Advance Level CTAL-TTA New Questions

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.

Testing that focuses on confirming that data backup tapes can be retrieved and loaded within specified service levels is classified as Continuity Testing. This type of testing ensures that business processes can continue after a disruption, such as data loss or system failure.

Explanation: Continuity testing specifically addresses scenarios where operational capacity must be restored and verified within business continuity planning frameworks, such as disaster recovery processes.

Analysis:

Web-based testing tools perform various functions to ensure that websites are functional, user-friendly, and perform well.

B. b and c:

B. To provide information on the size of the web pages and on the time necessary to download them:

Web-based testing tools often analyze the size of web pages and their load times to ensure optimal performance and user experience.

C. To scan and check that no broken or missing hyperlinks are present on a website:

These tools can crawl websites to detect broken or missing hyperlinks, ensuring that all links are functional and lead to the correct destinations.

Explanation of Incorrect Options:

A. To generate HTML and XML that is compliant with industry standards such as W3C:

This is typically a function of development tools rather than testing tools.

D. To allow applications to be tested by simulating a mobile platform's runtime environment:

This describes a function of mobile testing tools, not general web-based testing tools.

E. To provide an engine that allows a user to execute a model describing a system's intended run-time behavior:

This is more related to model-based testing tools rather than web-based testing tools.

General knowledge on web-based testing tools.

The pseudo-code provided for the "Win" program reads in variables A, B, C, and D. However, only variables A, B, and C are used in the conditional statements to determine if the output will be "Win" or "Loose". Variable 'D' is never used after it is read, which is a classic example of a 'defined but not used' data flow anomaly. This means that while there is an instruction to read a value into variable 'D', there is no subsequent use of this variable in the program's logic or output.
