var mockRepository = new MockRepository(MockBehavior.Default); var mockFoo = mockRepository.Create();
mockFoo.Setup(f => f.GetString()).Returns("Hello, World!");
mockFoo.Verify(f => f.GetString(), Times.Once());In this example, we are using the Verify method to check that the GetString() method was called on the mockFoo object exactly once. This is useful for ensuring that our code is interacting with the mock object in the way that we expect. Moq MockRepository is part of the Moq package library, which provides a wide range of tools and utilities for mocking objects in C# code. It can be installed via the NuGet package manager in Visual Studio or other development environments.
