Is it possible to parameterize a nunit test

If you are using NUnit 2.5.5 or above, this is possible using the TestCase attribute.

Normal unit tests would be decorated with [Test], but we can replace that as follows:

[TestCase("0", 1)]
[TestCase("1", 1)]
[TestCase("2", 1)]
public void UnitTestName(string input, int expected)
{
    //Arrange

    //Act

    //Assert
}

That type of thing will be the way to do it – obviously take different params.

Look at this for help: http://nunit.org/?p=testCase&r=2.5
