The test is conducted as 17follows: 18 191) AP ("AP 1") is brought up, and DUT connects to it 202) AP 1 is brought down, disconnecting the DUT from it 213) Another AP ("AP 2") is brought up, and DUT connects to it 224) DUT suspends while connected to AP 2 235) AP 2 is brought down, disconnecting the DUT from it while suspended 246) AP 2 is brought up again 257) Repeat steps 5-6 another 4 times (for 5 total iterations) 268) The DUT is woken from suspend 279) Verify that the DUT is connected to AP 2 upon resuming from suspend 28 29We verify the connectivity status of the DUT on resume by parsing shill logs, 30since the delays involved in waking a DUT from suspend using autotest framework 31make real-time checks inaccurate. 32 33Note: this test suspends the DUT for long periods of time, which may lead to 34flakiness if the ssh connection from the autotest host to the DUT has a 35ServerAliveInterval setting that is too low (i.e. less than the total suspend 36time).
