ISTQB Updated CTAL-TTA Exam Questions and Answers by diya

The common name for the automated testing technique that separates test input data and expected results from the control script is Keyword-driven testing. In this approach, test scripts are written using keywords related to the application under test, which are easy to read and can be interpreted by a script engine to perform testing actions.

Explanation: This methodology allows for the reusability of scripts and easier maintenance because the test data and the scripts that use the data are maintained separately.

Reliability testing is the process of checking whether the software consistently performs according to its specifications. For a commercial system with a critical internet-based user interface, ensuring that the application can handle connection failures without abnormal terminations is essential. Reliability testing would include testing the system's ability to recover from failures and continue operating, which directly addresses the risk identified.

To achieve 100% statement coverage, you need to ensure every executable statement in the code is executed at least once during testing. Given the code:

If x > y and z = 3 statement1 elseif z = 4 statement2 endif;

Two tests are required:

Test 1: Set x > y and z = 3 to execute statement1.

Test 2: Set z = 4 (irrespective of the condition x > y) to execute statement2.

With these two tests, both conditions that lead to the execution of statement1 and statement2 are covered.

Analysis:

Given the problems encountered with the first two websites, the types of testing needed for the BestForFood website should address similar issues related to performance under peak load and data volume growth.

Load Testing:

Load testing helps identify the behavior of the website under expected user load conditions. It simulates multiple users accessing the website simultaneously to ensure it can handle peak traffic without performance degradation. This is essential given the underestimation of concurrent user access for the first two websites.

Scalability Testing:

Scalability testing evaluates how well the system can handle increased loads by scaling up its resources, such as adding more servers or increasing database capacity. This is crucial for ensuring that the website can manage rapid data volume growth and increased user traffic over time.

Explanation of Incorrect Options:

B. Stress Testing:

Stress testing pushes the system beyond its normal operational capacity to identify breaking points. While important, it is more extreme than necessary for addressing the issues of underestimated user access and data volume growth.

D. Portability Testing:

Portability testing assesses how well the software can be moved from one environment to another, which is not directly related to the performance issues described.

E. Recoverability Testing:

Recoverability testing ensures the system can recover from failures, which is not the primary concern here.
