Producing a xUnit test output similar to Junit output on gitlab CI

Question

We have .NET Core 3 codebase and the unit and integration tests are ran on the Gitlab CI. Problem is, when one or more unit/int. tests fail, nothing specific is shown, you have to look at the entire pipeline dump and search to see for individual failed tests.

Looking at https://docs.gitlab.com/ee/ci/unit_test_reports.html, Junit report is exactly solving this issue.

Consulting with the How to capture structured xUnit test output in Gitlab CI?, I still wasn't able to find a proper solution. Main problem is, there are multiple test projects that are executed with the dotnet test command:

current snapshot of gitlab.yaml file:

  artifacts: 
    when: always
    reports:
      junit: ./Test.xml   
  script:
    - for proj in $(dotnet sln MySolution.sln list | grep 'Test.csproj$'); do dotnet test --logger "junit;LogFilePath=Test.xml" $proj; done

Now the problematic is the script part, where we iterate through all the test assemblies and do the dotnet test for each project.

Is there a way to somehow produce a single junit xml log file out of each project and feed it to junit test report in the

 reports:
  junit: ./Test.xml   

line?

Answer 1

You don't have to combine the reports. The artifacts:reports:junit key accepts multiple values, including glob patterns.

  artifacts:
    reports:
      junit:
        - "test.xml"
        - "./tests/*.xml"

So, one solution would be to have all your XML output files in a particular directory and use a glob pattern in your .gitlab-ci.yml file that matches the many files.

If you really want to merge the xUnit XML files isntead, see this answer
