The test checks the DNS client configuration on DUT. The validate.ping
entry must specify the "ping" command for all supported devices; the
test performs the ping, checks for the presence of remote IP address
in the output (= name resolution works), and then checks for the DNS
query on the DNS server (= DNS client works).
