A 0-switch test case is a test case that covers one transition from one state to another. To achieve 100% 0-switch coverage, all the transitions in the state diagram must be tested. The state diagram has seven states: Login, Menu, Logout, Withdraw, Deposit, Get Balance, and Access Account. There are 13 transitions in the state diagram, as shown by the arrows. Therefore, 13 0-switch test cases are needed. References =

The smallest set of test conditions to provide minimum coverage of the boundary values is the one that tests the minimum and maximum values for each category of carpet installation prices, as well as the values that are just above or below the boundaries. Option A covers these values, as it tests the boundary values of 0, 20, and 40 square yards, as well as the values that are one square yard more or less than these boundaries. It also tests the maximum possible value for the carpet area and the value that exceeds it. The other options do not test all the boundary values or have redundant values. References =

• Equivalence Partitioning Method3, section “Example 1: Equivalence and Boundary Value”

Boundary value analysis is a technique that focuses on testing the values at the boundaries of valid and invalid partitions. It is suitable for testing the errors caused by incorrect use of relational operators in the code, such as “>” and “<” instead of “>=” and“<=”. By creating test cases using boundary value analysis, the tester can verify that the system handles the borderline cases correctly and does not miss any edge cases.

1-switch coverage means that every possible transition from one state to another is tested at least once. Option C is the only test case that covers the transition from 2nd try to eat card, which is not covered by any other option. References = ISTQB Certified Tester Advanced Level Syllabus Technical Test Analyst, page 58, section 4.3.2.2.

The correct answer isD.Functional appropriateness.

Functional appropriateness

Functional appropriateness is the type of testing that ensures the application is suitable for the intended purpose and the user’s needs. It evaluates the relevance, usefulness, and user-friendliness of the application’s functions and features. In this case, the application should be tested for its suitability for senior citizens, who may have different preferences, expectations, and abilities than younger users.The interface should be easy to understand, navigate, and operate, and the application should provide adequate help and feedback to the users1.

The use case only describes the normal or happy path scenario, where the user performs a successful cash withdrawal. However, it does not consider any alternative or exceptional scenarios, such as invalid card, incorrect PIN, insufficient balance, network failure, etc. These scenarios are important to test the robustness and reliability of the ATM system, and should be included in the use case specification. References = ISTQB Certified Tester Advanced Level Syllabus Test Analyst, Section 2.2.1, Use Case Testing1; ISTQB Advanced Level Test Analyst (CTAL) Exam Study Guide, Section 2.2.1, Use Case Testing2

The correct answer isB.The information exchange between each system and its environment.

The information exchange between each system and its environment

The information exchange between each system and its environment refers to the compatibility and functionality of the systems with respect to the hardware, software, network, and other external factors that may affect their interaction.This type of testing is important to ensure that the systems can operate smoothly and reliably in different scenarios and conditions1.

The correct answer isA.Functional testing.

Functional testing

Functional testing is the type of testing that focuses on completeness, appropriateness, and correctness characteristics of the application under test. Completeness means that all the functions and features of the application are tested. Appropriateness means that the functions and features are suitable for the intended purpose and meet the user’sneeds.Correctness means that the functions and features produce the expected results and do not contain any errors or defects1.

Pairwise testing is a technique that reduces the number of test cases by testing only pairs of values for each data item, instead of testing all possible combinations. Pairwise testing is based on the assumption that most defects are caused by interactions of at most two factors. Pairwise testing can be applied to this problem using the classification tree, which shows the data items and their values. By using pairwise testing, the number of test cases will be lower than exhaustive testing, which would require testing every combination of values for each data item. References =

 Equivalence partitioning is a black-box test technique that divides the input domain of a system into partitions of equivalent data. Boundary value analysis is a technique that tests the boundaries of these partitions, where errors are more likely to occur. These techniques are suitable for testing the processing functionality of a critical traffic control system, as they can ensure that the system handles the input variables within the defined ranges and detects any invalid or out-of-range values. References = Black Box Testing Techniques: A Comprehensive Guide (Section 5.1 and 5.2), ISTQB Certified Tester Advanced Level Syllabus Technical Test Analyst (Section 3.2.1 and 3.2.2)

The correct answer isD.Traceability documentation.

Traceability documentation

Traceability documentation is a way of linking the requirements and use cases to the test cases, test results, and other artifacts that are related to them. It helps to ensure the completeness, consistency, and coverage of the testing process, as well as to facilitate the impact analysis, change management, and defect tracking.Traceability documentation should be added to the checklist for the requirements/use case review, as it is an important part of the test analyst’s role and responsibilities1.

A decision table is a technique that shows the possible combinations of conditions and actions for a given problem. A decision table that is not collapsed has one test case for each combination of conditions, regardless of whether the actions are the same or different. The tax system specification has three conditions: salary less than €20,000, married, and number of children between three and four. Each condition has two possible values: true or false. Therefore, the number of test cases for a non-collapsed decision table is 2^3 = 8. References =

A system architecture document is a document that describes the structure and behavior of a system, including its components, interfaces, communication protocols, and dependencies. It is typically used by a Test Analyst as the test basis for interoperability testing, as it provides the necessary information to design test cases that cover the interactions between different systems or components. A system architecture document can also help to identify potential risks and challenges related to interoperability testing, such as compatibility issues, performance bottlenecks, security vulnerabilities, and data integrity problems. References = Interoperability Testing in Software Testing (Section 2.2), A Simple Guide to Interoperability Testing (with Examples) (Section 2.3), ISTQB Certified Tester Advanced Level Syllabus Technical Test Analyst (Section 3.3.1)

The test execution phase involves running the test cases and comparing the actual results with the expected results. The test analyst is responsible for analysing any anomalies or deviations from the expected results and determining their root causes. This task helps to identify defects, report them, and track their resolution. References =

The equivalence partitions are based on the size of the carpet purchase and the installation price. There are four possible sizes: small, medium, large, and extra large. There are three possible prices: $5, $4, and $2 per square yard. The smallest set of test conditions that covers all the equivalence partitions is to test each size with its corresponding price, plus a no purchase scenario. Option C is the only one that does that. Option A does not test the large and extra large sizes. Option B does not test the extra large size. Option D tests more than the minimum required. References = ISTQB Certified Tester Advanced Level Syllabus Technical Test Analyst, page 50, section 4.1.2.2.

Classification trees are a visual way of identifying test objects and data, and pairwise testing is a technique of generating test cases that cover all possible pairs of values from different classifications. Classification trees support pairwise testing by:

• Helping to identify inputs to be used by the pairwise test technique, as each class represents a possible value for a test parameter.
• Showing the combinations needed to cover all-pairs, as each test case is a selection of one class from each classification.
• Helping to identify particular combinations of interest, as the test engineer can use the tree structure to group or prioritize classes based on their relevance or risk. References = ISTQB Advanced Level Test Analyst Syllabus 2019, section 3.2.3; Smarter Test Design with Classification Trees and Pairwise Techniques, slides 6-12.

A test design tool is a tool that helps testers create test cases, or at least test inputs, based on the requirements and specifications of the software. It can use various techniques, such as equivalence partitioning, boundary value analysis, decision tables, state transition diagrams, etc., to generate test inputs that cover different aspects of the software functionality and quality. A test design tool does not validate models of the software, execute tests automatically, or trace tests to requirements, although these may be features of other types of testing tools. References = What Is Test Design : Tools and Best Practices; Test Design in Software Testing - A Comprehensive Guide; ISTQB Advanced Level Test Analyst Syllabus 2019, section 3.2.1.

In a keyword-driven test automation approach, the Test Analyst is responsible for defining the keywords that represent the actions and expected outcomes of the test cases. The keywords are then implemented by a developer or a tool as reusable functions or scripts that can be executed by the test automation framework. For example, the Test Analyst can define keywords such as “transfer”, “check balance”, “verify balance”, etc. for the account transfer user story. These keywords can then be used to design test cases in a data-driven or table-driven format, such as:

Exhibit B is the only state transition diagram that matches the text description of Acme’s elevator door rules. It shows that the doors can transition between four states: Opened, Closing, Closed, and Opening. The transitions are triggered by either commands (open or close) or sensors (opened or closed). The diagram also shows that the open command can reverse the closing state, and the close command can reverse the opening state, as specified in the text. The other exhibits do not show the correct transitions or conditions for the elevator door system. References =
