How can I test dependency injection in C#?

To test dependency injection in C#, you can use a mocking framework like Moq to create mock objects.

Can you show me a simple example using Moq?

Sure! First, install Moq via NuGet. Then, create an interface and a class that implements it. Use Moq to mock the interface in your tests.

What if I want to test a class that has multiple dependencies?

You can mock each dependency separately and inject them into the class. This way, you can isolate the class under test.

Are there any best practices for testing with dependency injection?

Yes, keep your tests focused, use meaningful names, and ensure that your mocks accurately represent the behavior of real dependencies.
