 89%  of OAI-PMH Karate tests run in August 21, 2020:  https://foliotest.testrail.io//index.php?/runs/view/181&group_by=cases:section_id&group_order=asc&group_id=1327  For some reason only a 40% of those tests is executed right now https://foliotest.testrail.io//index.php?/runs/view/1904&group_by=cases:section_id&group_order=asc&group_id=1327
