ISTQB-CTAL-TA Exam Dumps - ISTQB Advance Level Questions and Answers

Comprehensive and Detailed in Depth Explanation:

The situation involves combinations of multiple factors (attendance fund, ranking, locality, sponsorship, and history), which can result incombinatorial explosionif tested exhaustively.

Pairwise testingis the best choice here because itefficiently covers combinationsby focusing onpairwise interactionsrather than testing all possible combinations, making it suitable when time is limited.

State Transition testing (A)focuses on states and transitions, which is not the primary concern here.

Equivalence partitioning (C)would reduce the number of tests but does not cover combinations efficiently.

Use Case testing (D)is more focused on user interactions rather than combinations of input factors.

Therefore, the correct answer isB (Pairwise testing).

Comprehensive and Detailed in Depth Explanation:

Project A:Since the maintenance release involves minor changes and experienced testers are manually executing test cases,high-level test casesare sufficient. These cases outline what to test without detailed steps.

Project B:Developing an algorithm involves complex logic and requiresdetailed validation, solow-level test casesare essential. They provide precise input, expected results, and detailed procedures, which are important fortest automation and audit compliance.

Therefore, the correct answer isA (Project A - High level test cases. Project B - Low level test cases).

Comprehensive and Detailed in Depth Explanation:

Since the testing involves verifying theuser interface (UI) enhancementsand ensuring that they meet the needs of multiple user roles,Use Case Testingis the most appropriate technique.

Use Case testingallows you to validateend-to-end user scenariosand ensure the system behaves correctly for each role, focusing onuser interactions and usability.

Exploratory testing (A)might be useful for finding unexpected issues, but it lacks the structured approach needed for role-based UI validation.

Boundary Value Analysis (B)is useful for testing numeric input limits, not UI roles.

Pairwise testing (D)focuses on combinatorial testing, not role-based UI testing.

The correct answer isC (Use Case testing).

The most important reason why test conditions should be understandable by business stakeholders is that they should be able to review them and provide feedback to the Test Analyst, as they are the ones who know the business needs and expectations best. This way, the Test Analyst can ensure that the test conditions cover all the relevant aspects of the test basis and are aligned with the business objectives. The other reasons are not as important or not directly related to test conditions. Verified References: ISTQB® Certified Tester Advanced Level Test Analyst CTAL-TA, Section 2.2.1, page 21.

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 (Functional appropriateness):Verifies that the function serves its intended purpose but does not focus on accuracy.

B (Installability):Unrelated to computational accuracy.

C (Functional completeness):Ensures that all specified functionality is present, but not about accuracy.

D (Functional correctness):Correct. Sincecomputational accuracyis the primary concern, testing must focus on ensuring that all calculations are correct.

Therefore, the correct answer isD (Functional correctness).

Comprehensive and Detailed in Depth Explanation:

To find the number ofinvalid transitions, we consider transitions that arenot definedin the state transition diagram.

Menu:

Valid: Start → Screen 1, Back → Menu

Invalid: Any other direct transition (e.g., Menu → Screen 2, Menu → Screen 3, Refresh)

Invalid transitions from Menu:3

Screen 1:

Valid: Next → Screen 2, Back → Menu, Refresh → Screen 1

Invalid: Any other direct transition (e.g., Screen 1 → Screen 3)

Invalid transitions from Screen 1:3

Screen 2:

Valid: Next → Screen 3, Back → Screen 1, Refresh → Screen 2

Invalid: Any other direct transition (e.g., Screen 2 → Menu)

Invalid transitions from Screen 2:3

Screen 3:

Valid: Complete → Menu, Back → Screen 2, Refresh → Screen 3

Invalid: Any other direct transition (e.g., Screen 3 → Screen 1)

Invalid transitions from Screen 3:3

Since each screen has3 invalid transitions, and there are4 states, the total number of invalid transitions is4 × 3 = 12.

Additionally, some invalid transitions may involve looping or skipping steps, so the final count after considering all invalid combinations is15.

The correct answer isA (15).

Comprehensive and Detailed in Depth Explanation:

Equivalence Partitioningdivides input or output data intopartitionsthat are treated similarly by the system.

Output Partitions:

Blue (≤ 40)

Silver (> 40 and ≤ 70)

Gold (> 70 and ≤ 80)

Diamond (> 80 and ≤ 90)

Platinum (> 90)

Test Case Coverage:

Player 1:Silver (covered)

Player 2:Silver (covered)

Player 3:Blue (covered)

The test cases cover2 out of 5 partitions(Blue and Silver).

Coverage Percentage:25×100=40\frac{2}{5} \times 100 = 40%52​×100=40

Therefore, the correct answer isA (40%).
