| 5 # This test run is designed to test that the connection manager is able |
| 6 # to roam to a previously connected AP when it loses connectivity to its |
| 7 # current AP on resume. To accomplish this, we join one AP (so we are |
| 8 # sure that flimflam remembers it), then join a second AP which we |
| 9 # shut down while the DUT is suspended. We sit around and observe |
| 10 # if and how long it takes for the connection manager to re-acquire |
| 11 # connectivity to the first AP. We expect the DUT will resume, find |
| 12 # the previous AP is gone, and then roam to the other AP. |
