ISTQB-CTAL-TA Exam Dumps - ISTQB Certified Tester Advanced Level - Test Analyst (CTAL-TACore)v3.1.2

The test set D provides the best equivalence partitioning coverage, as it tests on single boundary value fully for each partition. Equivalence partitioning is a technique that divides the input domain into subdomains that are expected to behave similarly. The partitions for this scenario are:

Before 9:30 am (full fare)

Between 9:30 am and 5:00 pm (saver ticket)

Between 5:00 pm and 7:00 pm (full fare)

After 7:00 pm (saver ticket)

The test set D tests the boundary values of each partition (9:30 am, 5:00 pm, and 7:00 pm) and one value inside each partition (9:31 am, 4:59 pm, and 8:00 pm). Verified References: [ISTQB® Certified Tester Advanced Level Test Analyst CTAL-TA], Section 3.2.1, page 33.

Comprehensive and Detailed in Depth Explanation:

Project C:Since therequirements are vague and inconsistent, creatinghigh-level test casesis more suitable. High-level test cases are flexible and allow for interpretation, which is crucial when requirements are not clearly defined.

Project D:Since the project aims forregression testing,low-level test casesare more appropriate. They are detailed and specific, essential for consistency during repeated manual or automated regression testing.

Therefore, the correct answer isD (Project C - High level test cases. Project D - Low level test cases).

The test technique that should be used to define the required test cases for testing this new web site in its various environments is pairwise testing. Pairwise testing is a technique that tests all possible pairs of inputs for a given scenario using a mathematical algorithm to reduce the number of combinations. This technique is suitable for testing a system that has many input variables with different values or options, such as browsers, plug-ins, servers, and operating systems.

Comprehensive and Detailed In-Depth Explanation:

A (Pairwise and use case testing):Not ideal since use case testing is not as relevant to UI combination testing.

B (Pairwise and exploratory testing):Correct. Pairwise testing efficiently handles thecombinationsfrom multiple drop-down fields, while exploratory testing complements agile development (SCRUM) for discovering unexpected issues.

C (Decision table and checklist-based testing):Not the most suitable combination for this context.

D (Classification Tree and exploratory testing):Classification trees are less effective compared to pairwise in handling multiple combinations.

Therefore, the correct answer isB (Pairwise and exploratory testing).
