c# - How do you test private methods with NUnit?

Question

I am wondering how to use NUnit correctly. First, I created a separate test project that uses my main project as reference. But in that case, I am not able to test private methods. My guess was that I need to include my test code into my main code?! - That doesn't seem to be the correct way to do it. (I dislike the idea of shipping code with tests in it.)

How do you test private methods with NUnit?

Answer 1

Generally, unit testing addresses a class's public interface, on the theory that the implementation is immaterial, so long as the results are correct from the client's point of view.

So, NUnit does not provide any mechanism for testing non-public members.
