title: Nunit test setup method with argument
body: <p>Can we have a test set up method with arguments?
  I need a different set up for every test in a fixture.</p>
  
  <p>Do we have something (or similar way) as the hypothetical idea :</p>
  
  <pre><code>[SetUp]
  [Argument("value-1")]
  [Argument("value-2")]
  [Argument("value-3")]
  public void InitializeTest(string value)
  {
      //set env var with value
  }
  </code></pre>
