努尼特的数据驱动测试?

在MSTEST中,您可以执行以下操作:

[TestMethod]
[DataSource("Microsoft.VisualStudio.TestTools.DataSource.CSV", 
            "testdata.csv", "testdata#csv", DataAccessMethod.Sequential)]
public void TestSomething()
{
    double column1 = Convert.ToDouble(TestContext.DataRow["column1"]);
    ...
    Assert.AreEqual(...);
}

nunit 2.5中的等效代码是什么?
