Question
You have been assigned to test an application that allows users to conduct banking online. You have been asked to verify the various installation environments for the product. According to the specification the product supports four browsers (Edge, Chrome, FireFox, and Safari), three operating systems (Windows, Mac, Unix), and four languages (English, Spanish, French, German). As you are reviewing the specifications you realize that the actual operating system names and versions were not included, only the major category. From this, you conclude that if you pick one from each of these sets (for example, select Windows 10 for the Windows OS), that testing should be sufficient. from the test sets. For example, you are not interested in testing Safari with Unix in German. Which of the combinatorial testing techniques would be the best choice when you want to exclude certain combinations?

Explanation
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.
