Unit Testing ViewModels
Test business logic in isolation.
Why Test the ViewModel?
Your ViewModel holds the logic, so it is the perfect place to test. You can check behavior without ever launching the full UI. 🧪
Logic Lives Apart from Views
Because a ViewModel is a plain class, you can create one in a test and call its methods directly. This keeps your tests fast and focused.
