Insights test panel doesn't show any information

Hello,

in my project (php-project with phpunit) I would have a statistic about test results. In the config.yaml I started a step with running tests and save the result into a file with junit-format. After this, the file will handled by store_test_results. In topic of the build the number of tests are printed out, but after clicking on the tab and go to “Test Insights” there are no results. I only can take a look on the documentation how it should work.

After trying the given example I get the same issue.

So, what is my mistake? Do I forget something? Has anybody an hint for me?

Thanks!

Best Regards
Mathias
