Looks like this is a repackaging of http://caniuse.com/ http://caniuse.com/, which does test in each environment: http://caniuse.com/#info_faq http://caniuse.com/#info_faq using this custom-built site: http://tests.caniuse.com/ http://tests.caniuse.com/. No word at caniuse about devices tested, but if that matters then you have a bigger problem. It should be consistent if you have the same software version.
