How can I get the name of the DeploymentItem?

Question

I would like to get rid of some duplication in this code. Following the DRY principle.
As you can see, the name of the file/deploymentItem is repeated.

[TestMethod]
[DeploymentItem("TestData/TestExcel.xlsx")]      <-- 
public void GivenAnExcel_ConverToPDF()
{
    const string filename = "TestData/TestExcel.xlsx";     <-- 
    var result = pdfConverter.ConvertExcelDocument(filename);
    AssertIsPdf(result);
}

• Is there a way to access the DeploymentItem programmatically without using the filename?
  Or
• Can I get filename programmatically somehow?

No, I cannot use another test framework than mstest ;-)

Answer 1

You could simply do this:

[TestClass]
public class Test
{
    const string filename = "TestData/TestExcel.xlsx";

    [TestMethod]
    [DeploymentItem(filename)] 
    public void GivenAnExcel_ConverToPDF()
    {
        var result = pdfConverter.ConvertExcelDocument(filename);
        AssertIsPdf(result);
    }
}
