We're currently feeding the xml files to JUnit built-in plugin.

However, we'd like to know for how long, or when a test started to fail. The JUnit plugin is supposed to do that.

The plugin *has* been enabled for months now(there ain't that much history because we recently started cleaning up old builds).
A recurring failing tests will always show as failing for one build.

Something not properly configured on our side?

This is a freestyle python project which runs it's unittests and reports it's results through a junit compatible xml file.
These xml files are cleaned up from the file system when starting a new build.

Is there any more info I can provide?
