Either DBotClosedIncidentsPercentage does not have any test playbooks or that all test playbooks in this pack are currently skipped, and there is no unittests file to be found. Please create a test playbook or un-skip at least one of the relevant test playbooks. You can un-skip a playbook by deleting the line relevant to one of the test playbooks from the 'skipped_tests' section inside the conf.json file and deal with the matching issue, or create a new active test playbook and add the id to the 'tests' field in the yml.
