NSubstitute vs Moq: Which is Better for Mocking in .NET?

What are the main differences between NSubstitute and Moq?

NSubstitute and Moq are both popular mocking frameworks for .NET, but they have different approaches. NSubstitute is designed to be more intuitive and uses a simpler syntax, while Moq offers more features and flexibility, which can be beneficial for complex scenarios.

Which one is easier to use for beginners?

NSubstitute is generally considered easier for beginners due to its straightforward syntax and less boilerplate code. It allows new users to quickly grasp the concepts of mocking.

Can you give an example of how to create a mock with both?

Sure! In NSubstitute, you can create a mock like this: var mock = Substitute.For<IMyInterface>();. In Moq, it would look like this: var mock = new Mock<IMyInterface>();. Both achieve the same goal but with slightly different syntax.

Are there any performance differences between them?

Performance differences are generally minimal for most use cases. However, Moq might have a slight overhead due to its additional features. For most applications, either framework will perform adequately.
