The specification does not clearly define the dependencies between the power unit and the body style options. For example, it is not clear if the user can select a hybrid power unit and then choose a saloon body style, or if the hybrid option is only available after selecting a hatchback body style. Similarly, it is not clear if the user can select an SUV body style and then choose a hybrid power unit, or if the SUV option is only available with petrol or diesel power units. These dependencies affect the usability of the site, as they may confuse the user or limit their choices. The specification should specify the valid combinations of power unit and body style, and how the site will handle invalid or unavailable combinations. References = ISTQB Certified Tester Advanced Level Syllabus Technical Test Analyst, page 80, section 5.3.2.1.

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

Classification trees are a combinatorial testing technique that allows the tester to represent the data items and their values in a graphical form, and to exclude certain combinations by using constraints or rules. Classification trees can help the tester to visualize and organize the test data, and to generate test cases that cover all relevant combinations of values. The other techniques do not provide a convenient way to exclude certain combinations, or require more complex mathematical calculations. References =
