Publishing xunit test results in Azure Devops fails with "No Result Found to Publish"

Question

I want to publish xunit test results in an Azure Devops release pipeline using the "Publish test results" task Version 1.* and 2.*.

Although xunit test file is present and has content - I checked with ls and cat commands in the pipepline I get an error message like this:

2020-02-13T08:23:10.9093662Z Obtained XUnit Test Run Start Date: 2020-02-13T08:23:10.9092530Z and Completed Date: 2020-02-13T08:23:10.9092530Z
2020-02-13T08:23:10.9144214Z No Result Found to Publish '/home/vsts/work/r1/a/report/report.xml'.
2020-02-13T08:23:10.9149123Z Obtained XUnit Test Run Start Date: 2020-02-13T08:23:10.9148260Z and Completed Date: 2020-02-13T08:23:10.9148260Z
2020-02-13T08:23:10.9149993Z No Result Found to Publish '/home/vsts/work/r1/a/report/report1.xml'.

The two files report1.xml and report2.xml get discovered properly but Azure DevOps says No Result Found to Publishand hesitates to publish them.

Answer 1

If you're using dotnet test task in this way:

You may need to set VSTest instead of Xunit in Publish Test Result Task:

I met same message like yours and then resolve it by changing Xunit to VSTest. I think you may encounter similar issue.

In addition:

And as I know, built-in tasks such as Visual Studio Test task and Dot NetCore CLI task automatically publish test results to the pipeline, so you actually don't need a separate Publish Test Results task in the pipeline. See this for more details.

E.g： Dotnet test task by default will generate and publish test results:

Hope it makes some help :)
