Creating Your Own Fakes Instead of Using Mocking Libraries

This technical article discusses unit testing in C#/.NET, advocating for writing custom fake objects (stubs/mocks) instead of using libraries like Moq or NSubstitute. It covers the benefits (no 3rd-party dependencies, transparency, flexibility), explains key terminology (fake, stub, mock, shim), and provides practical code examples for creating and using a fake service in a test scenario.
