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

The test set B is the best test set to explicitly test on single boundary value fully, using boundary value analysis. Boundary value analysis is a technique that tests the values at or near the boundaries of an input domain. The boundaries for this scenario are:

Salary less than €20 000

Number of children at least three and less than six

The test set B tests the boundary values of each boundary (€19 999, €20 000, three children, six children) and one value inside each boundary (€19 998, €20 001, four children). Verified References: [ISTQB® Certified Tester Advanced Level Test Analyst CTAL-TA], Section 3.2.2, page 35.

Comprehensive and Detailed in Depth Explanation:

According to the ISTQB CTAL-TTA syllabus, theTest Analysisstage involves identifying test conditions based on test basis documentation, requirements, and risk analysis. The primary focus is on analyzing the test basis to identify what needs to be tested. Applying test techniques during this stage helps reduce the risk of missing important test conditions. Therefore, Option A correctly states that test techniques are applied to minimize the risk of omitting important conditions.

Option B is incorrect because combining multiple product risks into one test condition can lead to overlooking specific risks, which contradicts the goal of thorough test analysis.

Option C is incorrect as defining dates is part of planning, not analysis.

Option D is incorrect because producing high-level test cases and defining data are tasks related to test design, which follows test analysis.

This detailed breakdown aligns with the ISTQB syllabus, emphasizing that test analysis primarily deals with identifying test conditions through the application of test techniques.

The best way to identify the exploratory tests is to create test charters to be used to guide the testing. A test charter is a document that defines the scope, objectives, and approach of an exploratory testing session. A test charter helps to focus the testing on the most important aspects of the system under test and provides a structure for reporting and learning from the testing results.

The statement that best characterizes a test design tool is that a test design tool generates test inputs from requirements. A test design tool is a tool that supports the test design activity by generating test inputs or test cases from a specified source, such as requirements, models, or code. A test design tool can use various techniques, such as equivalence partitioning, boundary value analysis, decision tables, state transition diagrams, etc., to generate test inputs or test cases.

The comment that should be made about the Supercar specification is that boundaries for stock levels are ambiguous. The specification states that the site will allow an order to be processed if at least one of the chosen vehicle configurations is in stock, but it does not define what constitutes “in stock” or how many units are available for each configuration. This makes the specification unclear and inconsistent, as it does not provide enough information for testing or implementation.

Comprehensive and Detailed in Depth Explanation:

As aTest Analyst, the focus is primarily onfunctional and usability aspects:

R01:Validates that the new or amended data can be correctly read and processed — this is afunctional requirement.

R05:Evaluates whether the newuser interfacemeets the needs of hospital administrators — this is related tousability.

The remaining requirements (R02, R03, R04) involveperformance, security, and load testing, which are more suited for theTechnical Test Analyst.

Therefore, the correct answer isD (R01, R05).

Comprehensive and Detailed In-Depth Explanation:

Component Testing (C) focuses on individual components or units and does not address usability or role-based testing.

System Testing (D) is the first level where the complete and integrated system is tested as a whole. It includes testing non-functional requirements such as usability, accessibility, and suitability for different user roles.

User Acceptance Testing (A) and Beta Acceptance Testing (B) are done later and focus on validating the product according to user needs and real-world scenarios.

Since testing for role appropriateness and usability should start as early as possible in the testing lifecycle, the correct answer is D (During system testing).

Decision Table Analysis:

Age:Valid ranges (18-69), excludes those aged ≥70 or <18 (2 valid values).

Alcohol Consumption:≤14 units, >14 units (2 values).

Smoking Status:Smoker, Non-smoker (2 values).

Employment Status:Full-time, Not full-time (2 values).

After removinginfeasible combinations(like age <18 or ≥70), the possible combinations are reduced.

2 (age) x 2 (alcohol) x 2 (smoker) x 2 (employment) = 16possible combinations.

However, some combinations are logicallycollapsedor omitted, as irrelevant conditions are not covered.

After this collapsing, the total number ofnecessary test casesis8.

Therefore, the correct answer isB (8).
