| This test verifies that the DUT successfully reconnects to a network in dark |
| resume after getting disconnected from that same network while suspended. |
| This test simulates the cases where multiple disconnect and SSID appearance |
| events take place over a single period of suspension. The test is conducted as |
| follows: |
| |
| 1) AP ("AP 1") is brought up, and DUT connects to it |
| 2) AP 1 is brought down, disconnecting the DUT from it |
| 3) Another AP ("AP 2") is brought up, and DUT connects to it |
| 4) DUT suspends while connected to AP 2 |
| 5) AP 2 is brought down, disconnecting the DUT from it while suspended |
| 6) AP 2 is brought up again |
| 7) Repeat steps 5-6 another 4 times (for 5 total iterations) |
| 8) The DUT is woken from suspend |
| 9) Verify that the DUT is connected to AP 2 upon resuming from suspend |
| |
| We verify the connectivity status of the DUT on resume by parsing shill logs, |
| since the delays involved in waking a DUT from suspend using autotest framework |
| make real-time checks inaccurate. |
| |
| Note: this test suspends the DUT for long periods of time, which may lead to |
| flakiness if the ssh connection from the autotest host to the DUT has a |
| ServerAliveInterval setting that is too low (i.e. less than the total suspend |
| time). This test was verified stable with the ServerAliveInterval set to 900. |
