One way would be to comment out these tests, or really turn off the internet, and then these tests don't run.
Indeed, a successful DNS query does not mean that you can connect to the internet in general. FWIW pingr::is_online [1] implements a method that works well. Apple's Captive Portal test page is the best method to determine if you are online, in my experience.
