SetUp in derived classes with NUnit?

Question

If I have the following code:

[TestFixture]
public class MyBaseTest
{
    protected ISessionManager _sessionManager;

    [SetUp]
    public void SetUp() { /* some code that initializes _sessionManager */ }
}

[TestFixture]
public class MyDerivedTest : MyBaseTest
{
    IBlogRepository _repository;

    [SetUp]
    public void SetUp() { /* some code that initializes _repository */ }

    [Test]
    public void BlogRepository_TestGoesHere() { /* some tests */ }
}

...NUnit doesn't call the base SetUp routine. This is expected, and I don't have a problem with it in itself. I can get the derived SetUp to call the base SetUp first, like this:

[TestFixture]
public class MyDerivedTest : MyBaseTest
{
    IBlogRepository _repository;

    [SetUp]
    public new void SetUp()
    {
        base.SetUp();
        /* some code that initializes _repository */
    }

This is ugly. If it was a constructor, I wouldn't have to.

I could use the "template method" pattern, and have the following:

public void MyBaseTest
{
    abstract void SetUp();

    [SetUp]
    public void BaseSetUp()
    {
        /* base initialization */
        SetUp(); // virtual call
    }
}

I'm not particularly fond of this, either.

What do you do when their test classes need SetUp, and they're derived from another class that also needs SetUp?

Answer 1

You have to call the method directly.

   [SetUp]
   public void DerivedSetUp()
   {
      base.BaseSetUp();
      // Do something else
   }

Edit: I haven't tried it, but perhaps a partial method might work too. I'd prefer to do the above though.

Edit2: I've just tried using partial methods. It didn't work. Even if it did, I think it's still going to be easier to call the base class.
