Symbiote\ListingPage\Tests\FilterByRelationTest::testFilterByRelation
Test the behaviour - Select 'Page' or 'File' for ListType - Select 'Viewer Groups (SilverStripe\Security\Group)' for ComponentFilterName - Select 'Code' for ComponentFilterColumn
Make sure there's a page or file that should be listed has the 'Administrators' group as a viewers group. Assuming other fields are valid, visit the page, with /administrators as the last part of the URL. Source: https://github.com/nyeholt/silverstripe-listingpage/issues/19
