I recently upgraded jenkins and all our plugins and some of our builds are failing.

After investigation it turns out that we produce some nunit test xml files that have no test results in (we might have set a test to [Ignore] temporarily for example).

These used to work, and now do not.

Example xml:

<?xml version="1.0" encoding="UTF-8"?><testsuite errors="0" failures="0" name="RES.Coordinate.Calculation.Test.TurkeyTest" skipped="1" tests="1" time="">
<testcase classname="RES.Coordinate.Calculation.Test.TurkeyTest" name="ED1950_to_WGS84("T1",556351,4611739,27.67626007d,41.65371627d)">
<skipped message=""/>
</testcase>
</testsuite>

The output is as follows:
