Just connect to your Jenkins instance, localize the junit tests report folder (e.g. /data/jenkins/jobs/Jeronimo/workspace/Repository/target/surefire-reports
) and then issue this shell command:
grep -h "<testcase" `find . -iname "TEST-*.xml"` | sed 's/<testcase name="\(.*\)" classname="\(.*\)" time="\(.*\)".*/\3\t\2.\1/' | sort -rn | head
