What are the best practices for unit testing view models?

The best practices for unit testing view models include isolating the view model, using mock services, and testing properties and commands.

Can you explain why isolating the view model is important?

Isolating the view model ensures that tests are focused on the logic of the view model itself, without external dependencies affecting the outcome.

What tools do you recommend for mocking services?

Popular tools for mocking services include Moq, NSubstitute, and FakeItEasy, which help create mock objects for testing.

How do I test commands in my view model?

To test commands, you can invoke them directly and assert the expected outcomes, such as changes in properties or method calls.
