Check for network connectivity

[dap]

Check for network connectivity in tests and skip tests appropriately if unavailable.

Hi @dap, in this issue do you mean check the presence of internet connection? Maybe can we use the Net::Ping to check the connection? Or did you mean another thing with this issue?

Thanks for the answer!

I think that this issue was already done in tests, can you review or explain this issue? Maybe, it was closed ;-)
