A decision table is a technique that shows the possible combinations of conditions and actions for a given problem. To achieve 100% coverage of the decision table, all the combinations of conditions must be tested. The decision table has four conditions: debit card valid, PIN valid, amount approved, and dates available. Each condition has two possible values: yes or no. Therefore, the number of test cases for the decisiontable is 2^4 = 16. However, some of these test cases are invalid or redundant, as they do not reflect the logic of the problem. For example, if the debit card is not valid, then the PIN and the amount are irrelevant. Similarly, if the PIN is not valid, then the amount is irrelevant. Therefore, these test cases can be eliminated from the decision table. After eliminating the invalid or redundant test cases, only eight test cases remain, as shown in the table below:

The test conditions are the inputs and outputs that are used to define the scope and objectives of testing. They should be understandable by business stakeholders because they affect their expectations and satisfaction with the software product. Business stakeholders can provide valuable feedback to the test analyst on the test conditions, such as clarifying any ambiguities, suggesting any changes, or identifying any gaps or risks. References =

State transition testing is a technique that tests the behaviour of a system or component based on its transitions between states in response to events. It is suitable for testing systems that have complex interactions and dependencies, such as a car navigation system that needs to integrate with other car software components. State transition testing can verify the functional correctness of the system by checking if it responds correctly to different inputs and events, and if it reaches the expected states and outputs. References = ISTQB Certified Tester Advanced Level Syllabus Technical Test Analyst, page 54, section 4.2.2.2.

Pairwise testing is a test design technique that reduces the number of test cases needed to cover all possible combinations of input parameters, by testing only pairs of parameters at a time. It is based on the assumption that most defects are caused by interactions of at most two factors. Pairwise testing is suitable for testing systems that have multiple parameters with discrete values, such as browsers, plug-ins, servers, and operating systems. It can help to find defects that are related to the compatibility and interoperability of the system in different environments. References = ISTQB Advanced Level Test Analyst Syllabus 2019, section 3.2.3; Pairwise Testing or All-Pairs Testing Tutorial with Tools and Examples; Test Design Techniques, section 5.4.

The correct answer isA.Functional correctness testing.

Functional correctness testing

Functional correctness testing is the type of testing that measures the degree of accuracy in a mortgage rate calculation module of the software you are testing. It verifies that the module produces the correct results for different inputs and scenarios, such as different interest rates, loan terms, payment frequencies, etc.It also checks that the module complies with the specifications and requirements of the mortgage rate calculation1.

The correct answer isA.It can be used to anonymize production data.

It can be used to anonymize production data

A test data preparation tool is a type of test tool that allows data to be selected from an existing database or created, generated, manipulated and edited for use in tests.One of the capabilities of such a tool is to anonymize production data, which means to mask or replace sensitive or confidential information with fictitious or random data, to protect the privacy and security of the data and comply with the regulations1.

This is an effective method to employ business users in your testing effort because it allows them to leverage their domain knowledge and experience without requiring them to have technical skills or testing tools. Test charters are high-level descriptions of the test objectives, scope, and approach that guide the testers to explore the system and report any issues they find. Test charters are flexible and can be adapted to different test levels and types. They are also suitable for the V-model development lifecycle, which emphasizes verification and validation at each stage of the development process1

The iterative model is a cyclical process in which the software product is developed and tested incrementally in short cycles called iterations. Each iteration delivers a working version of the product that can be evaluated and improved. Compared to the V-model, which is a linear and sequential process that follows a fixed set of phases and activities, the iterative model requires a reduced set of standard test processes for each iteration, as well as more flexibility and adaptability to changing requirements and feedback. The test analyst and the test team might expect to make this adjustment when working on an iterative model project. References =

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 =

The correct answer is C. All the expected environments and combinations.

All the expected environments and combinations

Interoperability testing should target all the expected environments and combinations that the system will interact with in the real world.This will ensure that the system can function correctly and reliably with different hardware, software, network, and external factors that may affect its communication and compatibility with other systems1.
