[All CTAL-TA_Syll2019 Questions]

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.

You have determined that some of these combinations are not interesting and should be excluded 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?

APairwise testing

BOrthogonal arrays

CCause/effect diagrams

DClassification trees

The user should not experience an error that does not have a clear explanation and instructions for correction

User error protection is the degree to which a system protects users against making errors. It includes providing clear and helpful error messages, preventing or minimizing the consequences of errors, and allowing users to recover from errors. In this case, the test condition verifies that the application provides adequate feedback and guidance to the user when an error occurs, such as entering an invalid word, losing network connection, or encountering a system failure1.
