When do I use the TestFixtureSetUp attribute instead of a default constructor?

Question

The NUnit documentation doesn\'t tell me when to use a method with a TestFixtureSetup and when to do the setup in the constructor.

public class MyTe         


        

Answer 1

I think I have a negative good answer - the reason to use a constructor instead of the attribute is when you have an inheritence between test classes.

Only one method annotated with [TestFixtureSetup] will be called (on the concrete class only), but the other fixture initializers will not. In this case I'd rather put the initialization in the constructor, which has a well-defined semantics for inheritance :)
