How to use external files for vstest in Azure Pipelines

Question

I'm trying to start a unit test in Azure Pipeline which opens an external file (myReport.rdl). The goal is to check, if the DataSets passed to the LocalReport class are harmoniously with report definition. Unfortunately I'm getting following error:

"d:\a\1\s\TestResults\Deploy_VssAdministrator 2019-08-04 06_29_01\Out\Reports\myReport.rdl".

How to copy the .rdl file to the right place? Is there any other solution to that?

Code

      var localReport = new LocalReport(); // Microsoft.Reporting.WinForms
      localReport.ReportPath = ReportPath; // Reports/myReport.rdl 
      ... 
      localReport.Render("PDF", DeviceInfo, out _, out _, out _, out _, out var warnings);

Always post your code. An error with no code can mean a million different things. — Daniel, Aug 04 '19 at 09:23
Have you specified the `DeploymentItem` attribute on the test or in the `.runsettings`? — jessehouwing, Aug 05 '19 at 18:51

From the error you mentioned in your question. I guess you are using attribute [DeploymentItem(string filePath, string outputDirectory)]. The test task will always copy the file specified in deploymentItem filePath to this directory "../Out/outputDirectory(the outputdirectory you specified)/file".

For example: [DeploymentItem(@"MyData/myReport.rdl", "Reports")].
myReport.rdl will be copied to “d:\a\1\s\TestResults\Deploy_**********\Out\Reports\myReport.rdl". To use myReport.rdl in your test method, you need to point your ReportPath = @"Reports \myReport.rdl".

If you do not specify the outputDirectory like below example: [DeploymentItem(@”MyData/myReport.rdl”)].
myReport.rdl will be copied to d:\a\1\s\TestResults\Deploy_**********\Out\myReport.rdl". To use myReport.rdl in your test method, you can point your ReportPath = "myReport.rdl".
