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

The usability technique that can be applied in this situation is usability review, e.g., heuristic evaluation. Usability review is a technique that evaluates the usability of a system or component based on a set of criteria or guidelines, such as heuristics, standards, or checklists. Usability review can be performed without users, as it relies on the expertise and judgment of the reviewers.

Comprehensive and Detailed in Depth Explanation:

Classification tree toolsare specifically used during thetest designphase to visualize combinations of input data and generate test cases.

Coverage tools (A)are used during test execution to measure how much of the code has been tested.

Dynamic analysis tools (B)are used to find runtime issues, not during test design.

Comparison tools (D)are used to compare expected and actual outputs during test execution.

Therefore, the correct answer isC (Classification tree tools).

The most important information that is missing from this use case is the alternative behaviour, which describes the exceptional or error flows of events that may occur during the execution of the use case. For example, the use case should specify what happens if the user enters an invalid PIN, if the ATM runs out of cash, if the user cancels the transaction, etc. The alternative behaviour is essential to test the robustness and reliability of the system under test.

Comprehensive and Detailed In-Depth Explanation:

R01:Low likelihood, not the highest priority.

R02:Relates to Iteration 3, which is out of scope for Iterations 1 and 2.

R03:High impact and medium likelihood, relevant to both IOS (Iteration 1) and Android (Iteration 2).

R04:Medium impact and medium likelihood, less critical compared to R03.

Therefore, the correct answer isA (R03).

The test case D is needed to complete the test set and achieve minimum class coverage, based on the classification tree. A classification tree is a technique that shows thecombinations of inputs and outputs for a given scenario using a graphical representation of classes and subclasses. Minimum class coverage is achieved when at least one representative of each class is tested. The classes for this scenario are:

Power Unit: Petrol, Electric, Hybrid

Body Style: Saloon, Hatchback, SUV

The test case D covers the class Power Unit Hybrid and the class Body Style Hatchback, which are not covered by any other test case. Verified References: [ISTQB® Certified Tester Advanced Level Test Analyst CTAL-TA], Section 3.5.1, page 41.

Seven test cases are needed to achieve the minimum acceptable level of coverage for this use case. A use case is a technique that describes the interactions between a system and its actors to achieve a specific goal. A use case consists of a basic scenario and alternative scenarios that describe the normal and exceptional flows of events. The minimum acceptable level of coverage for a use case is achieved when at least one test case covers each scenario and each error condition. The scenarios and error conditions for this use case are:

Basic scenario: single-sided to single-sided

Alternatives: single-sided to double-sided, copy of a set, copy using the automatic document feeder

Errors: no paper in paper tray, paper jam, out of staples

The number of test cases is equal to the number of scenarios and error conditions, which is 7. Verified References: [ISTQB® Certified Tester Advanced Level Test Analyst CTAL-TA], Section 3.6.1, page 43.

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 type that is most likely being performed is functional correctness testing. Functional correctness testing is a test type that verifies that the system or component produces the correct results for a given set of inputs or conditions. This test type can detect defects such asnon-compliance to requirements, calculations that produce incorrect results, and improper handling of data or situations.
