Exam CTAL-TM Topic 2 Question 148 Discussion

A model-based testing strategy is a testing strategy that uses models to represent the desired behavior and structure of the system under test, and to derive test cases, test data, test procedures, and test oracles1. A model-based testing strategy requires an activity to select an appropriate quality standard, such as ISO 9126, to be used to guide the testing. A quality standard is a set of criteria, guidelines, or characteristics that define the quality attributes of a software product, such as functionality, reliability, usability, efficiency, maintainability, and portability2. A quality standard can help to define the quality requirements, objectives, and measures for the system under test, and to evaluate the quality of the test results and the test process3. Therefore, option C is the correct answer. Option A is incorrect because conducting a quality risk analysis with all affectedstakeholders is not an activity specific to a model-based testing strategy, but rather a general testing activity that can be applied to any testing strategy. A quality risk analysis is a process of identifying and assessing the quality risks that may affect the system under test, and prioritizing them based on their impact and likelihood4. Option B is incorrect because conducting operational profiling to determine the expected usage of the system is not an activity specific to a model-based testing strategy, but rather an activity related to a usage-based testing strategy. An operational profile is a statistical representation of the relative frequencies of the inputs, operations, and operating conditions of a system in its operational environment. Option D is incorrect because creating the test charters for the exploratory testing sessions is not an activity specific to a model-based testing strategy, but rather an activity related to an exploratory testing strategy. A test charter is a document that defines the scope, objective, and approach of an exploratory testing session. References: 1:
