In Permalinks, "Latest Test Result" field is not even shown for builds not completed in "lastCompletedBuild/testReport/"

### Jenkins and plugins versions report

In Permalinks, "Latest Test Result" field is not even shown for builds not completed in "lastCompletedBuild/testReport/"

As suggested in https://issues.jenkins.io/browse/JENKINS-72124 , we are raising the issue here.

In Permalinks, "Latest Test Result" field is not even shown for builds not completed in "lastCompletedBuild/testReport/"

This is because "lastCompletedBuild" can indicate passed or failed build. When build is failed, obviously, test report does not get generated.

Ideally, "Latest Test Result" field in Permalinks must instead point to "lastSuccessfulBuild/testReport/"

This is about the hyperlink under "Latest Test Result (no failures)" in your screenshot.

When build is successfully completed, it shows this field along with test results.
When build is failed completed, it does NOT show this field.
This brings inconsistency in the view. It would be good to continue to see the last test report.

it is not optimized way of executing tests, even when build is failed. So, it is requested to change this.

Solution is to show hyperlink for "Latest Test Report" from "lastSuccessfulBuild/testReport/" , instead of "lastCompletedBuild/testReport/" .
