title: Publishing xunit test results in Azure Devops fails with "No Result Found to Publish"
body: <p>I want to publish xunit test results in an Azure Devops release pipeline using the "Publish test results" task Version 1.* and 2.*.</p>
  
  <p>Although xunit test file is present and has content - I checked with <code>ls</code> and <code>cat</code> commands in the pipepline I get an error message like this:</p>

  <p>The two files <code>report1.xml</code> and <code>report2.xml</code> get discovered properly but Azure DevOps says <code>No Result Found to Publish</code>and hesitates to publish them.</p>
