Error publishing test results to Azure Pipeline

I build and test NET 6 app in docker which works well – I see test output in console. When I try to publish test results I encounter an error. Full task output:

Copy test results and publish steps

- pwsh: |
    $id=docker images --filter "label=test=$(Build.BuildId)" -q | Select-Object -First 1
    docker create --name testcontainer $id
    docker cp testcontainer:/testresults ./testresults
    docker rm testcontainer
  displayName: 'Copy test results'

  inputs:
    testResultsFormat: 'VSTest'
    testResultsFiles: '**/*.trx'
    searchFolder: '$(System.DefaultWorkingDirectory)/testresults'

Copy tests results without errors:

    I contacted my colleagues and turns out it's a bug in Azure. I replaced VSTest publisher and format with XUnit publisher and XML format - the XML was successfully uploaded. Another issue was that XML was only for one project in solution, so I ended up dropping that step all together because I don't really need this information anyway (if test failed, so fails build).

    • The xunit test publisher may be an issue here.
    • Try resolving the error by t by changing Xunit to VSTest.
    • And also, you don’t necessarily need a separate Publish Test Results job in the pipeline because built-in tasks like the Visual Studio Test task automatically publish test results to the pipeline.

    Please refer this MSFT doc Publish Test Results task for more information.
