The TestSettings.UnreachableAddress is using 192.0.2.0 which is documented in RFC5735 as a network to be used in docs/example code. On the Android devices in Helix the upstream network is configured to not route this address which results in a "Destination Net Unreachable" response which causes the timeout argument to ping to be ignored and ping returns immediately. Skip the test in these cases. Example output from ping on the device: ``` 1|sunfish:/ $ time ping -c 1 -W 2 -s 50 192.0.2.0 PING 192.0.2.0 (192.0.2.0) 50(78) bytes of data. From 131.107.5.118: icmp_seq=1 Destination Net Unreachable --- 192.0.2.0 ping statistics --- 1 packets transmitted, 0 received, +1 errors, 100% packet loss, time Oms 0m00.03s real 0m00.00s user 0m00.00s system ```

Does this text get localized on any OSes?

On Windows it is, but this file is specific to Unix where I haven't seen this output being localized.
We also already rely on the English strings in ParseReturnedPacketSize and ParseNumPingsSent.

maybe we should have an analyzer for == true and != false

@danmoseley this doesn't work because of the null conditional operator so we need the explicit comparison.
