How can I mock dependencies in MVVM architecture?

You can use mocking frameworks like Moq or NSubstitute to create mock objects for your view models.

Can you give me an example of using Moq for this?

Sure! You can set up a mock for a service in your view model like this: var mockService = new Mock<IMyService>();.

What about testing the view model with the mocked service?

You can inject the mock into your view model's constructor and then test its methods to ensure they behave as expected.

Are there any best practices for mocking in MVVM?

Yes, keep your mocks simple, avoid over-mocking, and ensure your tests are focused on one behavior at a time.
