| Tests our behavior after a resume when not connected before the suspend. |
| |
| This test: |
| 1) Sets up a network with a single hidden BSS. |
| 2) Connects the DUT to that network and that particular BSS. |
| 3) Takes down the BSS in view of the DUT. |
| 4) Waits for scan cache results from the device to expire. |
| 5) Places the DUT in suspend-to-RAM |
| 6) Bring the same BSS back up. |
| 7) Resumes the DUT. |
| 8) Watches to make sure the DUT connects to this BSS on resume. |
| |
| Note that since the BSS is hidden, and wpa_supplicant does not |
| know to explicitly scan for hidden BSS's, this means that shill |
| must be triggering the scans. |
