Hey there.
You’ll have to find a tool that exports unit test reports in SonarQube’s Generic Test Execution Format format. I’m not aware of any ones right now that are actively maintained.
To be honest, all this does is put the count of Unit tests on your dashboard. We don’t think it’s particularly useful and will probably remove it at some point.
Make sure you upgrade to SonarQube v9.9 LTS soon, not only to benefit from our Best LTS Ever™, but because soon we will systematically ask users to upgrade when they ask questions about earlier versions of SonarQube, which are now considered unsupported.
