Coded UI Test - Data Driven using an XML File

Question

 I have done data driven with csv and excel  but this is the first time i am trying to do with xml and not able to achieve it.
I am using the below to access the xml file,
[DataSource("Microsoft.VisualStudio.TestTools.DataSource.XML", "|DataDirectory|\\xmlfile.xml", "xmlfile#xml", DataAccessMethod.Sequential), DeploymentItem("C:\\xxxxx\\xxx\\DataLibrary\\xmlfile.xml"), TestMethod]
and the xmlfile.xml file looks like this,
<?xml version="1.0" encoding="utf-8"?>
<Data>
  <DataRow>
    <Num>123456</Num>
    <Name>action1</Name>    
  </DataRow>
  <DataRow>
    <Num>1412</Num>
    <Name>action2</Name>    
  </DataRow>    
</Data>
When I am trying to debug this is the error i am receiving,
Result Message:
The unit test adapter failed to connect to the data source or to read the data. For more information on troubleshooting this error, see "Troubleshooting Data-Driven Unit Tests" (http://go.microsoft.com/fwlink/?LinkId=62412) in the MSDN Library.
Error details: Object reference not set to an instance of an object.

Hi BK,
There is anything wrong with your Datasource attribute.
The correct DataSource attribute is like:
[DataSource("Microsoft.VisualStudio.TestTools.DataSource.XML", "|DataDirectory|\\data.xml", "Iterations", DataAccessMethod.Sequential), DeploymentItem("data.xml"), TestMethod]
Iterations is the name of the table in the xml file. On your side, it should be ‘DataRow’.
If your xml file is not in the project directory, then you need specify the absolute path of the file in DeploymentItem option.
