For a C#-based application with frequent UI changes, which testing approach minimizes maintenance?

The Page Object Model (POM) is a testing approach that minimizes maintenance in the context of frequent UI changes. POM separates the abstraction of the user interface from the test code, providing a modular and maintainable structure. This allows testers to adapt quickly to UI changes by updating only the affected page objects. Behavior Driven Development (BDD) with SpecFlow, Data-Driven Testing with NUnit, and MVVM architecture are relevant in different contexts but may not specifically address the challenge of frequent UI changes.
