The tool used for the tests was Zonecheck <http://www.zonecheck.fr/> Although these tests certainly contributed to the good technical quality of the name servers, they were removed both for commercial reasons (a registry has to make money to pay its employees) and because it was easier to have the same rules for ccTLDs and gTLDs (and ICANN forbids these technical tests in gTLDs).
