What is NUnit and Moq?
NUnit is a unit testing framework for . NET languages, and Moq is the most popular mocking framework for . NET. I will describe the step-by-step process of creating the test project, adding unit tests using NUnit, and mocking the dependencies using moq.
What is mock in C#?
Mocking is a process used in unit testing when the unit being tested has external dependencies. The purpose of mocking is to isolate and focus on the code being tested and not on the behavior or state of external dependencies. Mocks: A Mock is a much more sophisticated version of a Stub.
Can I mock a class?
unless the class is sealed or has no virtual methods or properties then it should be able to be mocked. In Moq you can’t mock concrete classes, for doing so and testing legecy code you can use unit testing tools that support it, like Typemock.
