You are assigned as a Senior Test Analyst to lead a project test team composed of business users. These users have extensive business knowledge, but no testing experience. There is another test team composed of in-sourced professional testers that will also be used for this project. Your business users will be assisting the project on a part-time basis. The development team is building an application using the "V-model" development lifecycle. Your company has automated testing tools and test management systems for use by dedicated test teams. What would be an effective method to employ your business users in your testing effort?
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?
