How do I run a set of nUnit tests with two different setups?

Question

(Sorry for the unclear title, please edit it if you can come up with a better one)

I wish to run the same tests over two different data stores, I can create the data stores in the Setup() method.

So should I have a super class that contains all the tests and an abstract SetUp() method, then have a subclass for each data store?

Or is there a better way?

See "Case insensitive string compare with linq-to-sql and linq-to-objects" for what I am testing.

A simple solution is this.

All your test-cases are in an abstract class for example in the TestBase-class. For example:

public abstract class TestBase
{
    protected string SetupMethodWas = "";

    [Test]
    public void ExampleTest()
    {
        Console.Out.WriteLine(SetupMethodWas);    
    }

    // other test-cases
}

Then you create two sub-classes for each setup. So each sub-class will be run a individual with it-setup method and also all inherited test-methods.

[TestFixture]
class TestA : TestBase
{
    [SetUp]
    public void Setup()
    {
        SetupMethodWas = "SetupOf-A";    
    }
}
[TestFixture]
class TestB : TestBase
{
    [SetUp]
    public void Setup()
    {
        SetupMethodWas = "TestB";
    }
}

This works wonderful. However for simpler tests parameterized tests are a better solution
