What is the focus of domain analysis in test design?

Domain analysis in test design primarily concentrates on identifying specific test scenarios for each domain. By focusing on the specifics of the domain, testers can recognize unique characteristics, requirements, and potential risks, which help in crafting relevant and impactful test cases. This approach allows for a more targeted testing strategy that enhances coverage based on the data and scenarios that are most pertinent to the application and its users.

While minimizing testing costs and performing exploratory test cases are important considerations within the broader context of software testing, they do not specifically pertain to the objectives of domain analysis. Generalizing test cases through equivalence partitioning, while a valid technique in test design, focuses on reducing the number of test cases by identifying sets of inputs that can be treated similarly. This is not the primary focus of domain analysis, which is more about in-depth understanding and exploration of domain-specific scenarios to ensure thorough validation of the application.
