How can I mock dependencies in NSubstitute?

How can I mock dependencies in NSubstitute?

You can use NSubstitute to create mock objects by calling the Substitute.For<T>() method. What specific dependency do you want to mock?

I want to mock a service that fetches data from an API.

You can create a mock of your service like this: var mockService = Substitute.For<IMyService>();. Then, you can set up the expected behavior.

How do I set up the expected behavior?

You can use mockService.GetData().Returns(expectedData); to specify what the mock should return when the method is called.

Can I verify if a method was called on the mock?

Yes, you can use mockService.Received().GetData(); to verify that the method was called.
