Could not find a part of the path in TFS Build for Unit Test Case

I am trying to Include my Unit Test Cases in my Build Pipeline to run these Unit Test Cases as a part of Build. Few of my Test Cases use the Test Data stored in the XML files in the Unit Test Project. These test run successfully in my local system. But when I am trying to run these test case as a part of TFS Build pipeline, these test cases are getting failed since the Build is unable to find these XML files for data.

I tried to replace the config file App Settings for the TFS Build path but it isn't working. Still facing the same failures for the test cases. Also tried include the these files as a part of bin folder, I can see the files are present.

Below is the exception I am getting when I run the Unit Test Run as a part of TFS Build.

Assert.Fail failed. System Exception: Could not find a part of the path 'I:\Agent-Win-C_work\495\s\STARS-2.UnitTests\bin\XMLStore\CustomerRequest.xml'.

Any Suggestions to resolve the issue

Hi Naveen, How do you reference the file in your code? Like SalamiArmy mentions you might need to use a deployment item but in any event from the stack trace it looks like the xml file is in a subfolder (XMLStore) do you refer to it with the full path or relative one? also for deployment item it would be [DeploymentItem(@"XMLStore\CustomerRequest.xml")] – Etienne
Hi Naveen, any update on this ticket, did you get a chance to implement the solution that SalamiArmy suggested? Were you able to resolve? – PatrickLu-MSFT
Well the suggestion provided by the SalamiArmy didn't worked in my case. We modified unit test code to load the test data using reflection – Naveen Billure

Not only do you need to include those xml files your test depends on, you also need to use the [DeploymentItem(Path within the bin, path to deploy to)] to deploy them to the test agent in the build.
